A laptop is a type of computer that is portable enough to be used while traveling. Most laptops share a similar clamshell form factor with the top lid of the laptop housing a display and the bottom section containing a keyboard and trackpad. The two sections are connected by a hinge and when you travel, you can fold the two halves together to protect the screen and keyboard.
Manufacturers have also developed several other form factors for laptops which offer different features from the “traditional laptop” described above. Generic laptops usually have a screen size of about 11 inches (28 cm) to 17 inches (43 cm). Smaller, lighter laptops are available, however, and are often referred to as ""subnotebooks"" or ultraportables. While the hinges on most traditional laptops can only bend so far, some laptops—called convertibles, hybrids, or 2-in-1s—can fold all the way around. These laptops usually have a touchscreen so you can use your fingers to control the device when the keyboard is flipped onto the back. Here’s an informative hybrid laptop comparison video from The Verge. Detachable laptops take this concept further by allowing a user to remove the keyboard entirely. Some notable early examples include the Surface Pro and Surface Book which you can see in this demo from Fstoppers.
Laptops are distinct from desktop computers which generally stay in one place in a house or office. Compared to these larger machines, laptops generally use less power but provide less overall performance because they cannot deal with heat as well. While some laptops are upgradeable and repairable, desktop computers provide a simpler experience because parts are widely available and interchangeable.
You can usually identify the manufacturer of a laptop by looking for their logo on the outside of the laptop, either on the back of the display, below the display, or on the bottom of the device. The name of the specific model is usually printed on the bottom of the laptop directly on the case or on an attached sticker. Failing this, you can often find the serial number/service tag nearby. Search online for a “support” or “check warranty” page for your specific manufacturer and enter the serial number for more information on your device.
Sometimes the laptop is totally dead. Sometimes it’s just a simple issue. Follow the steps below for some troubleshooting ideas. This page from Laptop Repair 101 has more tips.
The first issue to check for is the battery. Does the laptop work like normal if it is plugged into the wall with a reliable charger? If so, your laptop likely has a bad battery. You can find battery replacement guides here on iFixit or elsewhere if nobody has made one yet (perhaps you can make your own guide). Make sure the power adapter you’re using works with your computer and puts out enough watts to power your specific model. You don’t want to be the person who goes into a store for a repair just to learn that you were using the wrong charger (I’m speaking from personal experience here). Tip: give the laptop a bit of time after it is plugged in before you try turning it on.
Does the laptop have any signs of life? These include spinning fans, blinking lights, or beeps. These beeps or flashing lights often correspond to a specific issue which you can fix. For example, two beeps when a Dell laptop starts up generally indicates an issue with the RAM.
Check for issues with the screen. It’s pretty easy to think your laptop isn’t working even if the issue is completely due to the screen. If the screen doesn’t turn on, try shining a flashlight into the screen and look for any images. If you can see dim images, the backlight in your screen is dead and you will need to replace the display. This video from Adrian Black shows this same troubleshooting step for a TV screen. Also make sure you haven’t just turned the brightness all the way down. Woops!
Can you get into the BIOS? The BIOS is the basic firmware that runs when you first start your computer. You can sometimes enter the BIOS setup when the laptop starts by holding F2, F10, or the delete key on your keyboard when you press the power button. See this article from Tom’s Hardware for a more comprehensive list of the keys used to enter the BIOS for each brand of laptop. If you can access the BIOS but can’t get any further with a regular boot (a.k.a. an attempt to turn on the computer where you don’t hold the BIOS key) your laptop probably works fine, but you have an issue with the operating system. Check these extra troubleshooting guides for what to do when Windows doesn’t start (or Linux if you have that installed).
If none of these steps work, you might need to replace the motherboard or take it to a repair shop that can work on the issue with the motherboard. If the laptop has a separate power input board that is attached to the motherboard with a cable, you could try replacing that part first. Sometimes the motherboard works fine but isn’t receiving any power because of a bad power port.
The general rule of thumb for troubleshooting is that you want to rule out all other issues before deciding to replace/fix the motherboard because it is one of the more expensive components.
Dead pixels on a laptop screen look like dots that don’t change color no matter what they “should” display. Usually they are stuck fully white, black, red, green, or blue. You can sometimes ignore these screen pimples (I’ve got three on my display right now), but a large group can be super distracting. Use this dead-pixel checker webpage to find a stuck pixel.
This WikiHow guide provides some useful strategies for fixing a dead pixel, including flashing static on the screen via the JScreenFix website or applying slight pressure or heat to the stuck pixel area. If none of these fixes work, you can replace your display with some guides here on iFixit.
As explained in the “How a Laptop Works” section below, a computer produces heat which it MUST vent out. If your computer is hot, it’s not necessarily bad; the important statistic is the CPU temperature. If this reaches about 100 degrees Celsius, the computer will automatically shut off to protect itself. You can monitor the CPU temperature in Windows with a tool like RealTemp or on linux with the terminal command “sensors.”
The processor might be very hot if the heatsink or fan attached to it are clogged with dust. The best fix is to open up the computer and blow some compressed air into the fan to kick up the dust that builds up over years of use. You could also use a lint-free cloth or static-safe brush if you don’t want to hurt the environment. This iFixit news article explains some alternatives to compressed air (the “air” from a can of compressed air is really gaseous refrigerant chemicals which are pretty bad for the environment).
You might need a new battery. See the replacement guides here on iFixit or elsewhere on the web for instructions on removing the battery in your laptop.
Alternately, you might just be running intensive software on your laptop like a game, video editing suite, or a simulation program. These apps will eat through your battery like a teenager after a fast. You can check the current maximum capacity of your battery vs. it’s original maximum capacity using the “powercfg” command on Windows (guide here) or the “acpi” command on Linux (guide here).
Computers aren’t magic, though the power they provide is pretty magical. If you already know the ins-and-outs of computer tech, you can skip this section, but for the rest of the people out there this information might be helpful for the troubleshooting and repair tips shown in the section above. Much of this information is explained further on HowStuffWorks.
Let’s start on the outside of the laptop. The screen consists of an array of pixels which can each change their color individually. The resolution of the screen is measured as the number of pixels across the width and height of the display (e.g. 1920x1080 pixels). With some exceptions, the pixels in a display do not emit any light; instead, they change the color of light emitted by a backlight that sits behind the pixels. If either of these parts fails, they need to be exchanged in full.
On the inside of the laptop, the CPU (sometimes just called the “processor”) works as the brain of the machine. It executes all the code that comprises the programs you use everyday. The CPU generates heat which needs to be dissipated somehow—otherwise the computer overheats and shuts down. Lots of laptops have a heatsink to absorb heat from the CPU and a fan which blows cool air over this heatsink and moves warm air out the back/side of the device. If you remove the heatsink, you MUST apply new thermal paste to the CPU to allow for adequate heat transfer.
While the CPU works as the brain of the laptop, the motherboard is the nervous system. The motherboard is the thin board that takes up most of the space in the computer and is generally the largest component. It is made from fiberglass with tiny copper lines embedded in it that criss-cross the surface. These lines, usually called “traces,” allow the CPU to communicate directly with other pieces of the computer like the RAM and storage (see below). While some thick, older laptops have a socket for the CPU which allows it to be replaced, the two parts are often soldered together and cannot be replaced individually.
Before it is executed, the code used by the CPU is located in a temporary storage location called RAM. RAM components are either soldered directly to the motherboard (this makes repairers sad) or inserted into a slot on the motherboard (this makes repairers happy). In the second scenario, you can replace RAM that has gone bad or add more RAM to your computer; RAM soldered to the motherboard cannot be easily repaired except by a professional. This question on Quora explains why adding extra RAM isn’t always correlated to increased computer speed.
Your programs and documents are stored on a hard drive or SSD inside the laptop. Since hard drives literally consist of platters spinning at high-speed inside your laptop, they can eventually die or break with a sharp impact (shoutout to my resilient hard drive which survived being dropped down a flight of stairs). SSDs don’t share the same issues and are faster than hard drives, so performing a swap can make a big difference for your machine. Some SSDs, however, are soldered directly to the motherboard (not again!?) which makes it more difficult to repair without an expert technician.
The final component I’ll mention here is the battery. The battery provides power to the laptop when it is not plugged into the wall. The battery supplies this extra energy as the product of a chemical reaction that happens inside. Over time, this reaction produces unintended by-products and the battery wears out. Thus, the battery is fundamentally a consumable part and will need to be replaced after a certain amount of time. Some manufacturers glue down their batteries which (do you see a trend?) makes them harder to replace. If you’re feeling up for it, you can use some adhesive remover to remove this sticky manufacturing trick.
Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.
No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.
For more information about Dell Limited Hardware Warranty and Dell"s Accidental Damage service offering, see the Dell Warranty & Support Services page.
NOTE: Other damages may be considered customer induced if determined by Dell Technical Support, an on-site field engineer, or at the mail-in repair center.
The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.
Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.
Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.
If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.
Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.
Laptop users can strive to make the most of their laptops to maximize stability, longevity, and usability. Understanding and implementing a few best practices for the safe handling of their laptop will enable them to enjoy their laptop for many years to come.

Are you using a Windows 10/11 laptop but the computer screen goes black randomly? What do you do when your laptop screen goes black? Laptop screen black is an annoying thing but don"t be worried. Here, this post is written for you to fix a laptop black screen (2 cases) to run the computer smoothly.
According to users" feedback, computer getting a black screen is a common issue. Some users have reported that the black screen doesn’t always occur. However, when it does, the laptop screen goes black for a second; then 5 seconds later, it happens again. It can even repeat several times.
Perhaps you are experiencing a random PC black screen that can bother you a lot since there is not any error code or message giving you an idea where to start troubleshooting. Sometimes, you meet the situation - laptop screen black but still running/on.
An unexpected black screen can happen on Asus, Lenovo, HP or Dell laptops in a number of scenarios in Windows 10/11, which may stem from hardware issues and logical faults - for example, a connection problem with your display, power supply, hard disk, internal memory, graphics card, virus attack, mistaken operations, software incompatibility and more.
Tip: Sometimes you may receive a black screen when booting Windows rather than computer screen goes black randomly during use. In this case, you can read this post - Here Is the Way I Fix Black Screen Error When Booting Windows to find solutions.
No matter which method you use to fix the issue of the screen goes black randomly, in order to ensure your data security, we strongly recommend backing up your important files first of all since data loss may happen at any time and anywhere in case of a random black screen.
If the laptop screen keeps going black, you might be unable to enter the computer desktop. Then, you may ask: how can I back up my files in the event of an unbootable laptop? Actually, it is easy as long as you use a professional Windows backup software for Windows 11/10/8/7.
Here, we suggest using MiniTool ShadowMaker Bootable Edition to create a file backup when the screen goes black randomly. First, you need to use the Trial Edition of this software and create a bootable disc or USB flash drive by using the Media Builderfeature to back up files in WinPE.
Tip:If the laptop screen keeps going black for a few seconds but is able to go back to normal for a little bit allowing you to reach the desktop, you can directly back up files with Trial Edition rather than Bootable Edition.
Step 2: Then, this backup software for Windows 11/10/8/7 will run. Just go to the Backup page where you can view all system related partitions are selected in the Source section.
Here, your purpose is to back up files before fixing the random laptop black screen, so you need to manually choose what you need to back up. Just go to the Source module to enter the following interface, click Folders and Files and choose the significant files you want to back up in the pop-up window.
Step 3: Next go to the Destination module where some options are offered for you to choose. Just select one to store the backed up file image. Here, it is recommended to select an external hard drive or USB drive.
Tip: In addition to using MiniTool ShadowMaker for file backup, you can choose the Windows data recovery software, MiniTool Power Data Recovery, to restore files from the laptop with a black screen. This article - How Do I Solve Windows 10/11 Booting to a Black Screen with Ease shows you more information.
Right now, it is time for you to fix the random laptop black screen problem after you have backed up or saved your important data. Go to the next step to find the solutions.
As mentioned in the first part, your laptop screen may get black due to many reasons. Here in this part, we will show you the different solutions to laptop screen black but still running/on due to different cases: hardware issues and software issues.
The most common and critical hardwares that can cause laptop black screen are the power supply, liquid crystal display, memory bank, hard disk, motherboard, etc. So it is necessary for you to troubleshoot these one by one.
1. First, check your power supply. Sometimes, for a laptop, if the power itself has a problem, it is possible that the screen goes black even though plugging in an external power supply.
In this case, you can choose to remove the power from your laptop and plug in an external power supply. If the Windows can boot up, perhaps the internal power is corrupted. Just go to buy another to replace it.
2. If the power indicator is on all the time and the external power is plugged in properly, then a random laptop black screen is not caused by the power. So you need to carefully check the cooling fan port to see whether there is wind and check if the hard disk indicator light is on.
3. If there is no problem, restart your laptop and hear if there is a continuous beeping voice. If yes, perhaps the memory stick is loose. Just plug it back in.
4. Next, check your graphics card or liquid crystal display. Connect the external monitor to the external display interface of the laptop, restart Windows OS and see whether the external display can work normally.
If yes, the motherboard, CPU, hard disk, graphics card, and memory don"t go wrong. And perhaps it is the liquid crystal display that leads to the issue laptop screen keeps going black. And then you need an after-sales service to fix the displayer.
If the external displayer doesn"t show anything, the motherboard or graphics card may be broken. Also, you need to ask an after-sales service for help.
5. Sometimes, the laptop temperature is too high; in this case, if you often play games despite the heat dissipation performance bot being good, as a result, the screen goes black randomly due to the graphics card temperature being too high.
Check your graphics card to see if it"s burned out. If not, please clear the dust thoroughly, reclean the exhaust system, apply silicone, and replace the fan.
This way is an easy solution to laptop screen black but still running. Just use the Windows logokey +Ctrl+Shift+B keyboard shortcut to wake up your display. If Windows is responsive, a short beep will sound and the screen will blink or dim when Windows attempts to refresh the screen.
Step 1: If you are unable to see anything on the screen due to a black screen, restart your PC, when the blue Windows logo appears, press the power button and reboot. Repeat these steps several times until Windows 10/11 automatic repair is triggering.
Some of you report the issue - the computer screen goes black but computer still running. For example, you are listening to music or playing the games, but only the screen becomes black while the voice is still present. In this case, you can take the graphics card driver into consideration.
If the video driver isn"t working properly, you can uninstall it in Safe Mode, and then let the operating system reinstall the driver automatically in the process of a restart.
Step 2: Expand Diskpay adapter, find your graphics card driver and right-click on it to choose Uninstall device to fix laptop screen goes black but still on issue.
Note:To remove the driver from your laptop, you can also select the Delete the driver software for this device option. Sometimes, this is recommended, but note that if the operating system fails to find the driver online, you"ll need to download a correct driver for your video adapter from your laptop vendor"s website.
Perhaps the screen goes black automatically or turns black every minute, but can go back after moving a mouse. In this case, maybe it is due to the power setting of your laptop.
Tip:If your laptop screen randomly goes black, but it can still enter the desktop Windows, you can also go to Control Panel > Power Options to edit the plan settings, for example, never turn off the display and never put the computer to sleep.
Sometimes viruses can cause the screen to go black. If you haven’t installed antivirus software on your laptop or the installed program isn’t powerful enough to block the viruses or malware, viruses may attack your laptop.
To scan and remove viruses, you also need to boot in Safe Mode with Networking, then run the installed antivirus program or download one online, and next perform a full scan of your Windows system to fix laptop screen black but still running/on.
Right now, all possible ways to fix laptop black screen are shown to you. If your screen goes screen randomly, please try the above solutions to troubleshoot.
But firstly, you should use MiniTool ShadowMaker to back up your important files since the random black screen may lead to data loss due to all possible causes of the laptop turning black.
On the other hand, if you have any question regarding our software or any method to repair black screen on your Asus, HP, Lenovo or Dell laptop, please send an email to [email protected] or leave your idea in the following comment part.
If you travel with a laptop and iPad, you need this app. I needed a second screen, but Duet gives me even more. Full gesture support, customizable shortcuts, Touch Bar, tons of resolution options, and very little battery power. How is this all in one app?
Co-workers can’t believe I can share my desktop on my iPad and my iPhone. Look no further. This is a terrific addition to any office, remote or otherwise.
With the new Air feature that allows remote access to a laptop or desktop computer from anywhere in the world (with internet access), this app has become even more essential.
I just love this app. Especially when I am travelling for work an working from the company branches. Then I use my iPad as second monitor for Outlook, Lync and other chat while I use the laptop big screen for remote desktop to my workstation at the main office. :)
As head of an NGO, I travel a great deal to remote places around the world. It is very difficult to be productive, as power and internet availability are often a challenge. However when I am able to set up, Duet works like charm to improve productivity.

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.
Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.
In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.
If you are concerned about pixel anomalies on your display, take your Apple product in for closer examination at an Apple Store, Apple Authorized Service Provider, or an Independent Repair Provider. There may be a charge for the evaluation. Genuine Apple parts are also available for out-of-warranty repairs through Self Service Repair.*
With the revival of the “Start Menu” from Windows 8 to Windows 10, this user-friendly desktop UI (user interface) realizes a more operable multi-display function. Let’s take a look at how we can use this multi-display tool on a Windows 10 notebook or desktop PC.
On July 29 2015, Windows released their new operating system “Windows 10.” Devices equipped with Windows 7 or Windows 8.1 were given one year to upgrade to Windows 10 for free, and so the migration to the new OS (operating system) Windows 10 is happening much faster than previous Windows operating systems. Even corporate users who emphasize stability over innovation, will proceed to slowly migrate towards Windows 10 when Windows 7 support ends in 2020.
When using Windows 10 in your notebook PC or desktop computer you’ll notice one major change – the revival of the desktop UI. This UI was revived after the complete removal of the Start Menu in Windows 8/8.1 - previously present in Windows 7 and earlier - was met with mixed reactions. The latest UI has become much easier to use, with the modern UI “tile format” being integrated with a virtual desktop feature in order to enhance multitasking and workability.
With the new focus on the desktop UI, Windows 10 has naturally improved the display settings. For example the “multi-display” function (Multiple displays connected to one’s PC for simultaneous use) has been greatly improved. Let’s go through some of these surprisingly not well known Windows 10 multi-display functions found on both notebook PCs and Desktop PCs.
Example: EIZO LCD display FlexScan EV2455 connected to 13.3" 2in1 notebook PC (VAIO Z). Projecting the 13.3" notebook PC display to a 24.1" WUXGA (1920 x 1200 pixels) external display greatly enhances one’s work efficiency.
Example: The expanded display of two EIZO FlexScan EV2455 monitors connected to a desktop PC. Aligning two 24.1" WUXGA (1920 x 1200 pixels) monitors side by side achieves a combined resolution of 3840 x 1200 pixels.
Setting up a multi-display environment on Windows 10 is incredibly simple. When you connect a second display to your PC, Windows automatically detects the display and displays the desktop UI.
In this case we opened the multi-display function from the desktop UI by selecting the OS “Project” menu. From the taskbar, click on the Action Center (bottom right of screen) and select “Project,” or if you want to use the shortcut keys, press the Windows Key andP key and the “Project” menu will appear. There are four types of display methods that can be chosen. If you want to expand the desktop UI over two screens, select the “Extend” option.
Find the “Action Center” icon in the lower right taskbar, and click on the “Project” icon (left image). In the “Project” menu, out of the four options, choose how you want to display your monitors (right image)
From here the two screens’ position relative to each other, display size such as text (expansion rate), display orientation, the previous four display method settings, and the main / sub-display monitor settings can be changed. Additionally, if you cannot see your connected display, click on “detect” to try to find the display (if this doesn’t work we recommend reconnecting the cable and/or restarting your PC).
In the enclosed grey squares [1] and [2], the position of the two monitors relative to each other is displayed. It’s best to drag these two squares to suit the actual position of your monitors.
These days notebook PCs equipped with very high definition displays of pixel densities greater than full HD are growing, but when these units are connected to external displays the character and icon sizes can vary significantly between the original notebook PC and external monitor, making it difficult to work with. If that’s the case, the “Change the size of text, apps, and other items” slider bar can be used to effectively adjust the display sizes close to the each other.
In the “System > Display” menu the screen position, display size (enlargement ratio), display orientation, display method of the multi-display, and main/sub display can be set.
If you scroll down to the bottom of the “Display” menu there is an “advanced display settings” link. If you click on this, you can set the resolutions of the display monitors. Additionally, if you click on the “Advanced sizing of text and other items” link, you can change the settings for more detailed things like the size of items and text.
As shown above, Windows 10 has a new settings application installed which we recommend you use. But you can also use the “control panel” found in Windows 8 and earlier. To any familiar PC user, the conventional method of using the control panel to display various settings is still possible.
In Windows 10, the Snap Assist function that sticks the window to the edge of the screen is available, and even more convenient. If you drag the window to the left or right of the screen, the window will expand to fill half of the screen. This is also possible in the extended desktop function where two windows can be placed onto the left and right sides of each monitor, making a total of four open windows. This can also be accomplished with the shortcut keys Windows + left or right arrow.
After snapping the window to either the left or right using Snap Assist, the vacant area on the opposite side will list all other available windows that can be selected to fit that space. This is also a new feature of Windows 10.
In Windows 10, after a window has been snapped to either the left or right side using the snap function, the empty area in the opposite side will display all other available windows as thumbnails. Choose one of these windows and it will fill that side of the screen.
Furthermore in Windows 10, if a window is moved to one of the four corners of the screen, it will shrink to 1/4 the size of the screen, so that four windows can be displayed at once. Additionally, in a multi-display environment, if you are displaying too many windows and your desktop has become messy, click and drag the window you want to view and quickly shake it to minimize all other windows. You can also press Windows and Home.
Let’s take a look at how the Taskbar can be used to increase the efficiency of the multi-display function. Right click on the taskbar and select “Settings” to display the “Settings > Taskbar” menu. Let’s look at the multi-display settings that can be found here. If you want to display the taskbar on your second device, slide the “Show taskbar on all displays” option to “on” and the taskbar will appear on both devices.
Right click on the taskbar, and select “Settings” (Left image). In the “Settings > Taskbar” menu, scroll down to “Multiple displays” and you can choose how the taskbar will be displayed on each device.
There are three options to choose how the taskbar can be viewed. The “All taskbars” option will display the taskbar the same on both displays, with all the running program icons displayed on both display’s taskbars. The “Main taskbar and taskbar where window is open” will display all running program’s icons on the first display’s taskbar and also display the programs running on the second display in the second display’s taskbar. Finally if you select “Taskbar where window is open” the taskbar will be displayed on both displays, but a running program’s taskbar icon will only be displayed on the taskbar of the monitor that the program is displayed on.
The above image shows the difference between the “All taskbars,” “Main taskbar and taskbar where window is open,” and “Taskbar where window is open” settings. The Windows 10 voice-enabled personal assistant “Cortana,” time icons and the notification area will always display on the first monitor.
If you connect an external display to a notebook PC, being able to create a large-screen, high resolution dual-display environment can significantly improve one’s work efficiency. These days products with high density pixel displays larger than full HD are becoming more common, but if a notebook PC with a screen size of 13 or 14 inches is displayed on one of these high resolution displays, the screen will end up shrinking so that it’s difficult to read, and so it has to be enlarged by 150% or 200%. Therefore it’s not that resolution = workspace, but rather that your workspace is limited to the size of your screen.
But an external display with a mainstream 23 – 24" full HD (1920 x 1080 pixels) or WUXGA (1920 x 1200 pixels) model, connected to a notebook PC, will display in a similar size to the notebook PC making it familiar to the user, and providing a lot of work space.
For example you could do things like compare multiple pages at once in a web browser; create a graph on a spreadsheet and paste it into a presentation while reading a PDF document; do work on one screen and watch videos or view a social media timeline on the other; play a game on one screen while reading a walk-through on the other, or use an external color management monitor to check for correct colors. Using an external monitor in addition to your notebook PC allows all of these things to be done seamlessly without having to switch between windows.
Example: An EIZO 24.1 inch WUXGA display (FlexScan EV2455) connected to a high-spec 2in1 VAIO Z notebook PC (from here on the examples will display the same set-up). The VAIO Z notebook display has a high definition resolution of 2560 x 1440 pixels, but because the screen is only a “mobile” 13.3 inches, on Windows it is expanded to 200%. Adding this to the FlexScan EV2455’s 24.1 inch 1920 x 1200 pixel display, gives a vast area of work space. Of course, because the FlexScan EV2455 has a large screen and 1920 x 1200 pixels, the notebook’s display can be displayed at 100% without needing to increase the 1920 x 1200 pixels. This makes for comfortable browsing of multiple web pages as shown.
Example: On a large external display, you can watch an online video while searching for relevant information on your notebook. Of course you can surf the internet on anything, but the large external screen is perfect for enjoying video content.
If you have an external monitor with excellent color display, you can use the graphics software in your notebook PC whilst replicating (mirroring) the display onto the external monitor; creating color-accurate images while you work. The above image is an example of the “Fresh Paint” application.
A word of advice when choosing a monitor to connect to your notebook PC, in a dual display environment — having the two taskbars at the bottom of the screen be uniform makes it easier to use, but a notebook PC’s height cannot be adjusted, so choosing a product that can be easily adjusted is desirable. Furthermore, because a notebook’s display is situated at a fairly low height, an external monitor that can be lowered to the table surface is better.
On the other hand, if you have an external monitor that can be raised quite high, it can be situated on top of the notebook – achieving an extended workspace on a narrow desk. Additionally, if you have an external monitor that is capable of rotating to a vertical (portrait) position, you can take advantage of the long screen by using it for web pages, SNS timelines, and reading documents.
If an LCD display’s height adjustment range is wide, you can create a vertical multi-display environment like this, reducing the required width of your working space. The image gives the example of a VAIO Z and FlexScan EV2455, but if you tilt the screen of the VAIO Z, the FlexScan EV2455 can be made to not overlap as shown; naturally creating two screens.
If the external display is set in the vertical position, portrait photos and long lists of information can be displayed. The notebook PC cannot be used in the vertical position.
In our examples we used the EIZO 24.1-inch WUXGA display FlexScan EV2455 because it is a monitor with a height adjustment range of 131 mm and the ability to be vertically rotated, so it can be easily combined with a notebook PC. Additionally, because of the narrow “frameless” design, the black border and bezel (i.e. noise) is minimized as much as possible. It’s easy to appreciate how the visual transition from one screen to the other becomes naturally gentler on the eyes. This monitor will also suit any photo-retouching and content creation by correctly displaying the sRGB color gamut; i.e. displaying colors the same as those found in most notebook PCs.
It should be noted that in Windows 10, the “tablet mode” cannot be used in a multi-display environment. In Windows 8/8.1 a notebook PC could display the modern UI start screen while an external display could display the desktop UI, but in Windows 10 the multi-display environment is restricted to only using the desktop UI. This is one of the revived functions that were found to be most useful in Windows 7.
Although the notebook PC has become mainstream in recent years, the desktop PC is still popular for users who require high-performance or work efficient computers. So to these users who want to take advantage of their high-powered PCs and increase their productivity, we recommend the multi-display environment. Using large, high resolution displays in a multi-display environment gives you an unbeatable advantage.
Because there are no screen size or resolution restrictions like in a notebook PC, the desktop multi-display environment can use a flexible combination of screen sizes and resolutions according to your location, budget or application. If so inclined, using the previous EIZO monitor, a resolution of 5760 x 1080 pixels could be made from 3 monitors, 5760 x 2160 pixels from 6 monitors, and many more variations can be made.
Of course even a non-high-spec environment can find improvement in their work efficiency by using two mainstream 23 – 24 inch Full HD (1920 x 1080 pixels)/WUXGA (1920 x 1200 pixels) monitors, compared to just the one monitor.
An example of how a multi-display environment can be used in the business scene. The left display can display tables and calculations of statistical data, while comparing the graphs, and the right screen can be used to summarize the findings in a document. If this were just one monitor, you would be constantly switching between windows, but with two monitors you can see all the necessary data without needing to switch between windows; improving work efficiency and reducing transcribing errors.
An example of how map-based services can be used. On just one screen, the display range of a map is quite narrow, but with two screens, a map, aerial photo, information about the location, and photos from the location can all be displayed at the same time. You can take advantage of the realism of the large screen by doing virtual tours of tourist destinations.
An example of how the multi-display environment can help with photo re-touching. Rotating one monitor to the vertical position can help with retouching portrait photos, or editing long documents and websites. If you want to take advantage of a vertical screen, you need to choose a monitor that can be rotated or buy a separate rotating mount to attach your monitor to.
Most commonly when people want to build a multi-display environment, they start with one monitor, and then later add another one. Ideally, it’s best to purchase multiple monitors of the same model in the beginning. This way the screen size and resolution can be aligned, but also the color and aesthetics will match. But perhaps more importantly, because the monitors are the same age, any defects in the screen such as color variations can be found early-on by comparing the two monitors next to each other.
Another note for those who might be thinking about trying to build a multi-display environment, is that the more monitors you align, the wider your viewing angle will need to be. In order to be able to see each monitor clearly without having to move, you need to buy a product that has wide viewing angles. Furthermore, the more screens you have the harder it is to avoid light reflecting on your screen and into your eyes. To prevent this, we recommend buying a monitor with a glare reducing surface, which will make the screens easier to see and will be easier on your eyes. Additionally, as mentioned above we recommend a monitor with a narrow bezel and black border as it is space-saving and increases visibility among other advantages.
The 24.1-inch WUXGA display FlexScan EV2455 that we used, uses an IPS LCD panel with wide viewing angles and a glare reducing screen. Furthermore it has a narrow-frame design of only 6.2 mm (1 mm bezel and 5.2 mm black border). Therefore two monitors side by side will only have a gap of 12.4 mm, so you can make an almost noiseless multi-display environment. Another feature is the automatic dimming function (Auto EcoView) which leads to less eye fatigue, and less power consumption.
The FlexScan EV2455 has a narrow frame design of only 6.2 mm (1 mm bezel and 5.2 mm black border). This requires only 12.4 mm when two monitors are aligned, so the bezel doesn’t feel like it’s in the way.
Earlier we introduced the set-up procedure for Windows 10 “multi-display,” and also showed some concrete examples. Whether you use a notebook PC or the more conventional desktop PC, if you want to increase the work efficiency of Windows 10, using multi-display is highly effective.
Some important things to consider when choosing a product is of course the image quality, but also wide viewing angles, glare reducing specifications, a narrow bezel that is easy to see past, a stand mechanism that allows for a wide range of installation locations, functions to prevent eye fatigue and power saving measures.
Even compared to a PC, a monitor is still a possible long-term investment. Therefore we recommend that you do not compromise on quality; in the medium to long term if you think of the comprehensive savings made through increased work productivity, reduced burdens on your body, and reduced power consumption, high-quality display products may offer higher value. Considering that, the FlexScan EV2455 that we used from EIZO’s “FlexScan EV” series meets all of these elements and includes a 5 year warranty, making it one of the best products suited to a multi-display environment.
Before you give into your impulses and wipe your screen with whatever you have at hand, let us stop you right there. Your display is way more delicate than you think, and if you want it to last a long time in optimal conditions, you’ll need to treat it with proper love and care.
The good news is that cleaning a computer screen is more simple than you think. You only need a soft cloth, a tiny bit of water, and the most delicate of touches.
As you would expect, not all screens are created equal, and some are more delicate than others. The safest way to figure out the proper care for your screen is to search for the make and model of your device, find out if it has an LCD, LED, or some other type of display, and search for the manufacturer’s instructions on how to care for it.
If you want to skip all that, there’s an easy way to avoid making a mistake that might not only result in irreparable damage to your screen but to your entire device. According to Joe Silverman, owner of New York Computer Help, a tech repair center in New York City, no matter how much money you spent on your computer or tablet, it probably has an LED or an LCD screen if you bought it within the last three years—and neither type benefits from window cleaner or highly concentrated alcohol.
That’s the uppermost layer of your screen, which is extremely sensitive to the acidity in alcohol and in compounds like ammonia or propylene glycol. These are often present in cleaning agents such as window cleaners and degreasers. Using these liquids will corrode the surface of your screen, resulting in scratches or even smudges you won’t be able to get rid of.
“Underneath there it’s the most intelligent part of the laptop,” Silverman explains. “What happens is that the liquid will get through that first line of defense, and when it does that it’s going to really affect the sensors.”
Things get even trickier when you’re dealing with touchscreens. On models like the Microsoft Surface, the display is the main input—as opposed to your mouse or trackpad on a regular laptop—so it’s ultra-sensitive, Silverman says. Using a strong liquid cleaner like a degreaser or a bleach-based disinfectant can obliterate the top layer on the screen. Combine that with high pressure, and you can kiss your fancy touchscreen computer goodbye.
Another downside to newer computers is their size and weight. If you decided to splurge on a new laptop, for example, you probably found one that has top-notch components, but also a slick, lightweight design. This format is only possible if everything in your laptop is smaller and thinner. In the case of your display, a thinner screen means a weaker barrier between your computer’s guts and the elements in the outside world.
Caring for your screen is simple—it only takes a little bit of water and a dust-free cloth, such as a microfiber wipe or the piece of fabric that came with your glasses.
First, turn off your computer and disconnect the charger. This might sound paranoid, but the benefit is twofold—you avoid any chance of triggering an electrical surge, and your screen will remain black, which will make it easier to see any dirt and grime.
Pour a couple drops of water on your cloth. Forget paper towels or the sleeve of that soft cotton t-shirt you love—microfiber is your best bet. Still, no matter how soft it is, a dry wipe could always leave micro-abrasions on your screen. The moisture will also help gather dust and particles while lifting grease from your display.
Use circular motions starting in the center of your screen and moving outward, so you don’t leave any streaks. If you can see any droplets or water traces on the glass while you clean, you’ve used way too much water. Gently dab the residual H2O with an absorbent cloth or tissue paper and start again.
If you’re dealing with next-level gunk, you can use isopropyl alcohol at 70 percent or lower, Silverman says. “That percentage is very important,” he explains. “We’d only use 90 percent or higher on dummy parts that don’t have sensors, like top cases and keyboards.” In these extreme cases, spray the alcohol on the cloth, never directly on the screen, and wipe it gently.
Just like solar damage, screen damage is cumulative. The more pressure you apply, the more abrasive a product you use, and the more often you use it, the greater the damage you’re inflicting on the protective layer of your display and the delicate sensors underneath it.
Maybe you can get away with using a high percentage of alcohol or even a window cleaner on your computer screen once or twice. But if you keep at it, eventually you’ll see the deleterious effects.
“You’ll see discoloration, lines (vertical and horizontal); sometimes it looks pretty and rainbow-like,” Silverman says. “Sometimes it’ll blink and sometimes you’ll see droplets of water or liquid in the back of the screen. There’s a lot of ways in which damage appears.”
The best way to avoid damaging your screen while cleaning it is to simply keep it from getting dirty in the first place. If you have a laptop, cover the keyboard with a thin microfiber cloth before closing it to prevent finger grease from transferring to the screen. If you have a touchscreen, wash your hands often before you use it, but make sure you let your hands dry completely before you start tapping—the soapy water or liquid hand cleanser from your fingers can easily end up on the screen and corrode it.
Wet, newly washed hands can also be detrimental to regular computers. Silverman says he often sees such victims in his shop—computers completely dead after hand sanitizer rubbed off the owner’s hands, seeped through the keyboard, and ruined the inner guts of the machine.
Your phone was designed to be carried, dropped, tapped, swiped, smashed against your face for long periods of time, and stowed in the deepest corners of your bag. In other words, its screen is way more resilient than your computer’s.
Silverman explains that most iPhones and Samsung phones, for example, have screens made out of one thick piece of glass. These, as opposed to computer screens, have all the LCD layers fused together, making them much more difficult to damage. Still, if you’re using alcohol, he recommends keeping the concentration at 70 percent or lower, using a soft cloth, and applying only low pressure to get rid of any accumulated gunk there.
Be especially careful with charging ports, as contact with water (also present in rubbing alcohol) can damage the electronics inside your smartphone. Newer models often are resistant to liquids, but there’s always a threshold to how much they can withstand. And you probably don’t want to know what that is.
Replacing the screen of your computer or smartphone can be expensive, and even if that’s not an issue for you, no one wants their devices to fail when they need them the most. So remember these tips well—we hope you never have to read this article again.

Tablets are of growing interest in the classroom environment and are an innovative method for note-taking. When paired with a keyboard, tablets that meet the above requirements are sometimes even used as a replacement for a laptop. New tablet computers come with Windows, iOS or Android operating systems. Capabilities and the number of programs available depend on the operating system choice and the hardware of the device. Consult with your academic advisor if you are unsure about the need for a tablet in your field of study. Microsoft OneNote software for tablet computers is available for free through the Azure Dev Tools for Teaching program for Windows based tablets.
A laptop computer or notebook computer, also known as a laptop or notebook for short, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat panel screen (usually 11–17 in or 280–430 mm in diagonal size) on the inside of the upper lid and an alphanumeric keyboard (typically QWERTY) on the inside of the lower lid, although 2-in-1 PCs with a detachable keyboard are often marketed as laptops or as having a "laptop mode".pointing device such as a trackpad or trackpoint. Many modern laptops also have a built-in webcam and even a touch-screen display.
Laptops run on both an AC power supply and a rechargeable battery pack and can be folded shut for convenient storage and transportation, making them suitable for mobile use.business trips), in education, for playing games, web browsing, for personal multimedia, and for general home computer use.
The names "laptop" and "notebook" refer to the fact that the computer can be practically placed on (or on top of) the user"s lap and can be used similarly to a notebook. As of 2022, in American English, the terms "laptop" and "notebook" are used interchangeably;notebook" originally referred to a specific size of laptop (originally smaller and lighter than mainstream laptops of the time),
Laptops combine many desktop components and capabilities into a single unit, including the central processing unit (CPU), random-access memory (RAM), hard disk drive (HDD) or solid-state drive (SSD), and graphics processing unit (GPU). Most modern laptops include a built-in webcam and microphone, and many also have touchscreens. Laptops can be powered by an internal battery or an external power supply by using an AC adapter. Hardware specifications may vary significantly between different types, models, and price points.
Design elements, form factors, and construction can also vary significantly between models depending on the intended use. Examples of specialized models of laptops include rugged notebooks for use in construction or military applications, as well as low-production-cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or traveling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes.
As the personal computer (PC) became feasible in 1971, the idea of a portable personal computer soon followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968,Dynabook".IBM PALM processor.IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.
As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first "laptop-sized notebook computer" was the Epson HX-20,Suwa Seikosha"s Yukio Yokozawa in July 1980,COMDEX computer show in Las Vegas by Japanese company Seiko Epson in 1981,LCD screen, a rechargeable battery, and a calculator-size printer, in a 1.6 kg (3.5 lb) chassis, the size of an A4 notebook.
The portable micro computer Portal of the French company R2E Micral CCMC officially appeared in September 1980 at the Sicob show in Paris. It was a portable microcomputer designed and marketed by the studies and developments department of R2E Micral at the request of the company CCMC specializing in payroll and accounting. It was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. It was equipped with a central 64 KB RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (separate blocks), a 32-character screen, a floppy disk: capacity = 140,000 characters, of a thermal printer: speed = 28 characters / second, an asynchronous channel, asynchronous channel, a 220 V power supply. It weighed 12 kg and its dimensions were 45×45×15cm. It provided total mobility. Its operating system was aptly named Prologue.
The Osborne 1, released in 1981, was a luggable computer that used the Zilog Z80 CPU and weighed 24.5 pounds (11.1 kg).cathode-ray tube (CRT) screen, and dual 5.25 in (13.3 cm) single-density floppy drives. Both Tandy/RadioShack and Hewlett-Packard (HP) also produced portable computers of varying designs during this period.flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The US$8,150 (equivalent to $22,880 in 2021) GRiD Compass 1101, released in 1982, was used at NASA and by the military, among others. The Sha
