A black screen at boot is bad news. It"s tough to diagnose a problem without any information on the screen. If you"ve got a black screen on boot, various things can cause the problem on Windows 10 and Windows 11.

We"re going to detail ways to try to resolve a black screen on a Windows 10 or Windows 11 computer, from simple hardware checks to reinstalling your display driver.

It"s important to check that your computer and Windows are actually booting. To do this, press Windows key + Ctrl + Shift + B. This command actually restarts your graphics driver—which might itself fix the black screen—but also emits a beep.

If you hear a beep, then Windows is responsive. However, if you don"t hear anything, it could suggest that your computer isn"t booting. If that"s the case, see our guides on repairing a PC that won"t boot and how to fix a black screen of death.

If you have a black screen from boot, a key step is to check the display connection. It might sound simple, but it"s where many black screen problems arise.

If you can, use another monitor connection. For example, move from HDMI to DisplayPort. Alternatively, use a new cable. This will help you determine whether the issue lies with the monitor port or the cable.

If possible, connect your monitor to a different computer. If it has a black screen there too, it"s a sign the monitor is faulty, so you should contact the manufacturer. You can also try using another monitor on your computer.

Turn your computer off and disconnect all of your external devices. This includes your mouse, keyboard, external hard drive, and so on. Restart your computer and see if you still get the black screen. If you don"t, plug each device in one at a time until you find what"s causing the problem.

With the problematic device identified, try updating its drivers. See our guide on how to find and replace drivers if you need a hand with that. No luck? Browse through the device manufacturer"s support site and contact them for further help.

It may be that your system"s projection settings are set incorrectly. For example, your display might be set to project on a second screen that doesn"t exist, thus causing your monitor to show a black screen.

Press Windows key + P to bring up the Projection menu. From top to bottom, the options are: PC screen only, Duplicate, Extend, and Second screen only. While the first is the default, yours might not be set to it.

Press P to highlight the next option and Enter to select. Repeat this four times to get back to the original setting, though hopefully one of the settings along the way will bring your display back.

To reinstall display drivers, you"ll need to boot into safe mode. The method you need depends on various factors, so follow the appropriate steps below and then continue reading to discover how to reinstall your display drivers.

Once restarted, select Troubleshoot > Advanced options > Start-up settings > Restart. Again, your system will restart and present you with different options.

You need access to a working computer so that you can create Windows 10/11 installation media. Download Windows 10 or Windows 11 from Microsoft and then use this to create installation media. If you need help on that, see our guide on making a bootable ISO.

You then need to set the boot order in the BIOS to read your installation media first. Again, if you need a hand, see our guide on how to change the boot order.

If this doesn"t work or isn"t an option, select Uninstall to remove the driver completely. Then, go to the manufacturer"s website (likely AMD, NVIDIA, or Intel) and install an older driver or contact them for support.

Your computer may be overheating, which can result in a black screen. It"s very important that you keep your PC cool because it extends the lifespan of your components.

Turn your computer off, unplug everything, and open it up. As a first step, grab a microfiber cloth and air blower and use this to clean out all dust and dirt inside your computer, especially from the fans. It"s best to do this outside if you can, since it will kick up a lot of dust. Try not to let it settle back inside the computer.

Turn your computer off, unplug everything, and open it up. Look over all your components for signs of damage. Remove each component and reseat it, ensuring it"s firmly secured.

Have you recently upgraded something inside your computer, like the graphics card or RAM? If so, this is a prime culprit for causing a black screen. If you"ve verified the component is installed correctly, contact the manufacturer as the part may be faulty.

Alternatively, your power supply unit (PSU) may not supply enough power to support the new parts, which causes the computer to black screen and shut down. Use an online power supply calculator to ensure that your PSU is suitable.

Hopefully, working through these steps has solved your black screen problems. While it can be scary, it doesn"t mean that your data has vanished, so keep calm.

If you don"t have a black screen, but instead one that"s constantly flashing, you should still try some of these steps as it"s often caused by the same issue.

The black screen of death is caused by a critical error in your computer’s operating system that can happen because of a faulty device driver, a hardware defect, or a Windows software glitch. While usually fixable, finding the root cause of the black screen isn’t always easy.

If you see the full black screen before login, it’s probably caused by a malfunctioning device driver or hardware issue. If the blank screen happens after login, there’s probably something wrong with Windows, like a buggy Windows 10 update, or a problem with an installed application. Don’t assume your computer is permanently failing — if you think it’s a hard drive issue, check out our hard drive failure guide.

First, we’ll outline solutions for a black screen before logging in. Then we’ll discusssolutions for a black screen of death that happens after logging in.

If you get a black screen before the Windows login screen appears, the issue often has an easy fix. Check out the possible solutions below to troubleshoot the issue.

If you get a black screen only occasionally, try disabling some startup items to optimize your boot. With AVG TuneUp, you can turn off all non-essential applications and put them to sleep automatically. AVG TuneUp features a built-in Sleep Mode so you can get the most out of your RAM and CPU power and have more resources available at startup.

If everything is working normally until suddenly your PC displays a blank screen, something might be wrong with your computer cables or monitor. Here’s how to check your cables and other important connections.

Disconnect and reconnect all of your video cables — HDMI, DVI, DisplayPort, and VGA. While you’re at it, blow into the ports to dislodge any dust or other particles that may have got stuck there.

Constantly unplugging and plugging in cables causes them to wear out over time — eventually, they break. It’s especially common if you use a laptop and an external monitor.

To check whether your cable is causing the black screen, try plugging in a different video cable, like the one from your TV, that you know works. If that cable connection produces an image instead of a full blank screen, it’s time to get a new computer cable.

Your monitor display might be defective or set to the wrong source, which can also lead to a black screen. Try connecting to a different display if you have one. Or, move from your monitor to your TV (or vice versa).

The blank screen might be caused by a mismatch between your monitor and your resolution. For example, an optimized gaming PC might not work with a projector that can’t display the high resolution. If your Windows 10 PC shows a “boot error” when connected to a projector, try hooking it up to a regular monitor. If the regular monitor displays images normally, the root of your problem is likely a very low resolution, which the projector can’t display.

Sometimes, external hard drives, USB connections, Wi-Fi antennas, or VR headsets cause issues during boot. If your laptop screen is black upon startup, unplug everything not necessary for your PC to work — leave only your monitor, mouse, and keyboard plugged in and restart your computer.

On a bigger desktop computer, try removing all unnecessary components, such as sound cards and extra RAM sticks. If that doesn’t work, you can also switch out the graphics card and upgrade your RAM completely.

BIOS is the core program that runs older PCs, while UEFI runs newer models. BIOS/UEFI regulates basic hardware configuration and makes sure the operating system launches.

If you’re getting a black screen of death, try reverting to the default settings. Here’s how to reset BIOS/UEFI: Turn off your PC, then hit the power button to turn it back on. Immediately during startup, you’ll get a prompt to hit a certain key to enter setup (usually F2 or the DEL key). Hit that key repeatedly.

Find an entry that says Load defaults (or Optimized defaults or something similar). BIOS/UEFI looks different depending on your device, but the general wording of the entry should be similar. Selecting this option resets everything back to default settings.

The BIOS/UEFI also controls how your PC starts up. Your PC could boot from a hard disk, a CD/DVD (e.g., rescue disks), a USB thumb drive (to install Windows), or even a floppy drive. In Boot Priority (or First Boot Device) settings, ensure the hard disk option is selected.

You can also check your BIOS/UEFI performance by running a CPU stress test. If your computer fails the test and causes the black screen of death, your BIOS/UEFI drivers might be outdated. You can easily update your drivers with one of the best free driver updaters on the market.

If your PC boots to a black screen, you should restart your PC several times. After doing this repeatedly, the Windows Startup Automatic Repair screen should launch automatically.

If the Windows repair doesn’t work, you need to create a bootable Windows 10 drive, plug it in, and use the disk-boot tip above to make sure your PC boots from the USB drive.

Hit Next, then wait for Windows to restore all necessary files and return things to working order. In some cases, you might need to reinstall an application or an update that you installed after the restore point and before you got the black screen of death.

Windows Safe Mode launches your PC with the minimum amount of drivers or programs running, which will help you avoid a black screen. Safe Mode means only Windows launches — eliminating any interference from unnecessary programs or drivers.

To boot into Safe Mode, follow the steps above to launch the Windows Repair tool. This time, click Startup Settings. If you don’t see that option, click See more recovery options, then click Startup Settings.

Then, turn off all startup items using the Task Manager. Right-click your taskbar, select Task Manager, then go to Startup. Turn off everything in this tab by right-clicking each item and selecting Disable.

Now, reboot the system normally. If the black screen is gone and everything is working, reverse the options above one by one. Enable one item in Task Manager, reboot, and ensure everything works. Then, repeat the process with the next item on the list. This will help you identify the program preventing your system from rebooting.

As mentioned above, a faulty device driver can cause an unbootable system. To fix this, uninstall any device drivers that could be a problem. Right-click Start and select Device Manager.

Go to the problematic device driver (usually drivers like display adapters, network adapters, or sound, video, and game controllers). Double-click the entry, such as NVIDIA GeForce GTX 1650, go to the Driver tab, and select Roll Back Driver. Click Yes to confirm.

If you want to update your drivers immediately and keep them updated automatically, get AVG Driver Updater and run a free scan. AVG Driver Updater’s easy-to-use dashboard will help you identify and update your outdated or faulty drivers, fix lingering driver issues, and get your computer working optimally again.

If the black screen of death happens after you log in (you enter your password and then everything goes blank), you can still find the cause of the black screen using one of the solutions below.

If you see a black screen after login, something is affecting your Windows operating system while it’s trying to load your desktop and icons. Usually, it’s an application that’s loading automatically. To disable it, press the Ctrl + Alt + Delete buttons simultaneously, and select Task Manager.

If the black screen prevents you from getting to Task Manager, follow the advice above on how to boot into Safe Mode. In Task Manager, go to Startup and disable every item. Reboot your computer, and check that everything works normally.

The program explorer.exe (Windows Explorer) is responsible for loading your desktop and icons. If that program isn’t loading, then Windows Explorer isn’t running automatically like it should after login, and all you’ll see is a black screen with a floating cursor.

On the right side of the screen, double-click Shell. Check that the Value data section reads explorer.exe. If this field is empty or something else is there, enter explorer.exe.

If something else is written in the Value data section, it could be a virus, malware, or some other potentially unwanted program. To find out, Google the name of the program and do some research. Even if your search doesn’t turn up any information, you should run a virus scan immediately.

A strong antivirus program like AVG AntiVirus FREE will scan your machine from top to bottom to find any malicious code. Then, it will delete the malware and set up defenses to detect and block any future signs of trouble.

If your computer screen keeps going blank seemingly at random, the cause of the black screen of death might be your graphics driver. Make sure to update all AMD, Intel, and NVIDIA drivers regularly so that your graphics card works properly. Check out our detailed instructions on how to update your graphics drivers and our guide to monitoring GPU performance.

If your PC is connected to multiple monitors or even a VR headset (which Windows identifies as a monitor), you can accidentally hit the wrong button and switch your output to a screen that’s off. When you see a blank screen, hold down the Windows key on your keyboard and press P. This shows you the possible display modes, and allows you to switch.

Hopefully, this guide has helped you solve your black screen problems. If all else fails, you may need to reinstall Windows from scratch, because the issue is likely more serious or beyond fixing. Otherwise, keep your system fresh by maintaining it on a weekly basis to help prevent issues like the black screen of death.

To keep your machine clean, optimized, and running as smoothly as possible, use AVG TuneUp for PC. AVG TuneUp’s Automatic Maintenance feature tunes your machine weekly, while its Sleep Mode feature disables unnecessary applications. And the built-in Software Uninstaller gets rid of apps that could render your system unbootable. Try AVG TuneUp today and say goodbye to Windows black screen issues.

Your Windows system and the data in it may mean the world to you. However, it is still a device that can run into various problems. Here, we’re talking about the ‘no display on boot’ issue. Several users have posted queries stating that they can turn on the computer but can’t see anything on the screen. The display appears blank. Even the GPU fan spins at full speed, but there is no display. So, why is it happening? How can it be fixed?

We dug deeper into the matter and found some tips and tricks that may help. However, before that, let’s understand the different states of no display on boot problems.

The primary reason you get no display on your PC could be damaged or loosely connected cables. Other reasons may include incorrect display configuration, faulty or problematic GPU or RAM, incorrect BIOS configuration, faulty peripheral devices, or damaged PSU (Power Supply Unit).

You should check your power connections if you face the “no display on boot” error. There might be some connection errors between the power sockets and the PC/monitor.

Now check if the power light on your monitor is on. If the light is ON, reboot your system and press Windows key sequence (Windows + Ctrl + Shift + B command) to wake the screen. It will restart your Graphics driver.

If there is no light on the monitor, check if the cables connected are damaged. Try the cables on another PC or attach other cable cords to your system.

If the above diagnosis doesn’t help you overcome the ‘no display on PC’issue, try resetting your BIOS settings. This method will help you check if the RAM is at fault here. When you power on your PC, it runs POST (Power-on-self-test), verifying if all hardware is identified before BIOS initiation. It also displays on-screen if the RAM is working fine. As long as your monitor receives power, you may access the BIOS utility and reset it to fix multiple issues.

Turn on your system with the Power button and press the BIOS key (usually F2/F8/F10/F11/F12/Del). You can also check for the BIOS key online by visiting your device manufacturer’s site.

The Voltage Selector Switch may be set to the correct switch, but it’s worth checking. It is a physical button given at the back of the PC. The switch lets you balance your device’s internal circuit with the input voltage. If it is set improperly, it may affect your system’s boot function.

Usually, the default value set by the Voltage Switch doesn’t need any changes as it matches your country’s requirements. But if you bought it from an overseas dealer or just moved to a new country, you would need to adjust the Voltage Selector Switch considering the country’s requirements. For example, your system may happily work for 110 volts. You can also refer Foreign Electricity Outlet Guide.

Sometimes, there may be a conflict between the peripheral devices, causing a black (blank) screen or no display on your screen. It includes your Bluetooth, speakers, mouse, webcams, external storage drivers, keyboard to cameras, scanners, etc.

An outdated, corrupt, or incompatible device driver may cause no display on a PC or laptop. Rolling back or updating these drivers may fix the problem. For this, you would need to boot your PC into Safe Mode.

Tip:If you successfully boot your PC in Safe Mode, restore your data with reliable data recovery software, such as Stellar Data Recovery Software to prevent future data loss.

You can also check your CPU performance in BIOS to determine if no display on boot issues occurs due to PC overheating. However, this method will only work if you can access your system in Safe Mode. Follow the given steps:

When you see the BIOS page emerging, click PC Health Status, System Hardware Monitor, or similar options. (The category name may vary depending on your system brand.)

Try rebooting your system. Sometimes, only a restart fixes the problem. However, if it doesn’t, you can refer to the Microsoft page to troubleshoot black screen or blank screen errors.

If there is a faulty battery on your system, it may remove all your boot settings. Hence, you can see nothing but only a black screen while booting your system with a damaged CMOS battery.

There could be many reasons for the black screen of death in the Windows system, including graphic card errors, disk errors, unexpected OS behavior, faulty display, malware infection, or peripheral devices malfunctioning. However, the error is fixable.

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 your laptop screen is not displaying any image, several troubleshooting steps might help you resolve the issue. Review each section below for steps that might help.

When you encounter video-related issues in Windows, you can quickly reset your computer"s graphics driver using the keyboard shortcut Windows key+Ctrl+Shift+B.

If you see a white screen or a rainbow of colors, this could mean the video card in the laptop is defective. In this case, the video card or graphics chip needs to be replaced by an authorized repair center for your brand of laptop.

Although you may not see anything on the screen, listen to the laptop for sounds indicating it"s booting. If you don"t hear any sound, follow the steps in the link below before moving to other sections on this page.

Newer computers with an SSD and no other drives can be silent even during a normal boot. Therefore this suggestion should only be followed for laptops with a traditional hard drive.

A laptop battery may cause problems with booting and displaying anything on the screen. Even if you can charge it to full capacity, the battery may have a defect causing it to interfere with the laptop start-up process. Try the following steps to rule out a possible battery issue.

If the laptop starts up but nothing is displayed on the screen, continue with the troubleshooting steps below. Review the following page if the laptop does not turn on or boot up.

Restart Windows to see if it"s a temporary issue and resolves itself with a reboot. If the problem persists, erase your hard drive and reinstall Windows.

If the picture is partially visible, the laptop"s brightness is too low or turned down by a power setting. Make sure your laptop is not in a power-saving mode by plugging the laptop into the wall. Next, try increasing the brightness on your laptop to verify that it is not causing your issue.

If you have an external display connected to your laptop, like a computer monitor, the laptop screen may not display anything. The default action on some laptops is to display an image only on an external screen if connected.

Most laptops have a function key with a secondary action that toggles where and how the laptop displays an image. Pressing that key may fix the issue, telling the laptop to display an image on the laptop screen and the external screen. Below are two examples of what the function key with screen toggle may look like on your laptop.

Verify there is no issue with the laptop graphics card by connecting a monitor or another external display to the laptop. If the external display works fine, it"s an issue with your laptop LCD screen or the connection from the motherboard to the LCD screen.

If an external monitor doesn"t work and you read through the details on the page linked above, the internal graphics card, motherboard, or video cable is defective. You may need to have the graphics card or motherboard replaced. Take the laptop to a computer repair shop to see if it can be repaired.

You can also check to see if the laptop is overheating. In most cases, a laptop shuts off when it overheats; however, it may only turn off the display by cutting power to the GPU (graphic processing unit).

If the laptop still has a black or blank screen after following the steps above, there is a hardware issue. The list below displays the most common hardware failures.

If the laptop is not under warranty, unfortunately, for most end-users, repairing a bad LCD or motherboard can be complicated or may result in further damage if not done properly. We recommend you take the laptop to a repair shop and have them replace the defective hardware.

However, one of the primary advantages that makes it a prime choice for most people (especially working-class individuals and students) is its mobility while packing similar performance of a PC.

Unlike a desktop computer where you can remove and replace damaged parts yourself, a laptop cannot. One of the biggest examples, which is our core focus here, is screen issues. It isn’t the same when it comes to a PC where you can easily purchase a new monitor to replace the broken one. A laptop needs professional repairs to fix that issue or at worse requires consideration in buying a new unit entirely – which is most often the case.

Let’s start with one of the most common laptop screen issues – no display or blank screen. There’s a lot of reason behind this problem. Fortunately, there are also plenty of troubleshooting procedures you can try that might probably fix it.

First of all, you should confirm that when you turn your device on, it powers up just like normal – power icon is lighting up, the HDD (hard disk drive) is running, and the fan is spinning. That is to make sure what you’re experiencing is indeed a “no display” screen issue. There are two primary causes: Motherboard has faulty hardware parts, or the LCD or LED is broken. Either one of the two is what’s causing the problem, and knowing which is the key to solving it.

First and foremost, start checking the screen if it is truly the one causing the problem. You can do this by connecting your laptop to an external display – a computer monitor or a smart TV works well. Turn your device again, if it shows a boot up on the external screen, then it’s guaranteed that your laptop’s screen is, in fact, the issue.

Having a defective LED or LCD is an easy repair, but you should first check if your laptop is still under warranty. If it is still under warranty, go directly to the nearest repair hub and do not attempt to fix it yourself. If it’s not, you can go to a computer parts supplier or, better yet, laptop manufacturer’s certified parts dealer and purchase a replacement screen. We suggest that you bring your laptop with you to get the exact screen replacement and eliminate the risk of getting the wrong one.

Before you continue and replace the part yourself, take note that you are doing this at your own risk and we are not held accountable for any damage, injury, or data loss during the process.Steps in replacing the defective screen:

Test and turn your laptop on – you do it first before returning the bezel back in place just in case it still won’t work (although chances are pretty slim, the replacement itself could be defective)

Once you can see your computer booting up and the screen now functions properly, the repair is complete. It’s not a hard fix, but it takes patience and time to execute correctly.

As mentioned above, if it still doesn’t work after connecting your laptop to an external screen, we proceed to the second step. In this step, we are going to check your device’s BIOS (basic input/output system).

For some reason, a computer’s system may go haywire even if things were running smoothly. A quick and straightforward solution is to reset its BIOS. Here’s how to do that:

This process should reset your laptop’s bios, and if that was the only problem, your computer should run without any problem. You are then free to insert the battery back in. However, if your computer still doesn’t display anything, proceed to the next step.

One of the leading causes, about 90%, of no display issues in both laptop and desktop computers is due to a faulty RAM (random access memory). The problem may be as simple as having a dirty memory stick, or it may be broken and needs replacement. Fixing this problem is as easy as resetting the bios.

If your laptop has two memory slots and two chips – and if unfortunately it still did not work – you should make use of only one chip and one slot at a time and perform a test. To elaborate, choose only one chip and use it in one of the slots, and then turn your device on. If that fails, use the same chip but insert it in the other slot. Again, if that still fails, use the unused chip then redo the previous steps.

If your device works after doing the above, apparently, one of those two memory sticks is the problem. If both of the chips did not work, you could further verify by borrowing the same type of memory chip (a working one) from a friend and test it on your laptop. If it works, you should purchase new RAM chips/sticks for replacement. Again, bring the defective RAM to the store to accurately get the same type – you may choose to upgrade if you like but it should match correctly.

If the three steps above didn’t solve the “no display” issue, there’s a huge chance that your laptop’s problem is within the motherboard or GPU. In that case, you can’t do anything about it. The best option you have is to bring your laptop to a repair centre and let the professionals deal with it, or you can also buy a new unit instead.

If your laptop’s LCD or LED screen has some visible black dots or lines, you should first try to press it – just enough force that will alter the display. Most of the time, this problem is due to trapped or wedged pixels. Applying pressure on it will usually loosen and free the pixels, and when it is unstuck, the dots and lines will disappear.

However, if applying pressure to it doesn’t remove or alleviate the dots, then the only way to solve it is by replacing the screen. Most of the time, monitor lines and dots are usually bearable and poses no hindrance to productivity or usage – so as long as that’s the case, there is no need for replacement.

Another common problem is when your display is darker than usual. First of all, you have to make sure that you set your laptop’s brightness level to maximum. If that does not work, then there are two other ways you can do yourself to fix the problem.

Firstly, you can try closing and opening the lid. Most of the time, your laptop just lagged and didn’t follow the system protocol immediately or the lid switch was stuck. Manually closing and opening the lid back again usually solves this issue.

Secondly, you can do a quick restart/reboot. It may just be a minute system error or problem that can be solved by restarting your device. After it has fully booted up, you can assess if it’s still dimmed.

If both didn’t work, there might be hardware problems – burnt backlight or inverter, or broken cable. We do not advise you to do these manually as it is more complicated than replacing the screen. Doing it on your own may destroy the circuit board (which is quite expensive) and backlight lamp. The lamp itself contains mercury (extremely hazardous to your health) and lead glass – it’s brittle and may cause static charges and electrocute you when repairing it without the proper tools.

If your laptop’s screen is messing up – colour is incorrect, divided screen, or jumbled display – it’s often due to a defective GPU. There is nothing you can do but send your laptop to a professional repair centre. It requires replacing the GPU, which is almost always connected to the motherboard. It also needs precision tools to repair successfully, without so, you may worsen the damage.
