A while back I was sitting around and wondering what to do with my dead laptop. I knew the mother board was fried but everything else was still in working condition. As a result, I decided to make an external monitor from my dead laptop and proceeded to do the research to find out if this was possible. Below is what I discovered. Unfortunately, there was no way to use the motherboard"s VGA connector. The VGA connector on a laptop is used to connect to an external monitor. In any case the VGA connector is output only and wouldn"t work for an external screen. As a result, I found that I needed to buy a controller board for the LCD screen, to make it work as an external monitor. This was the main cost but was still less than half the cost of buying an external monitor.

Step one. Unplug the dead laptop from any power source AND remove the battery!. The laptop battery is located, usually, on the bottom and can be removed by sliding a release lever. These are lithium ion batteries and can hold a few Amps. The risk of shock might be minimal. However, there is no need to take the risk.

Step Two. To Remove the LCD screen from the laptop, you will need to remove the screws. There are rubber pads on the front of the LCD screen to protect it when the laptop lid is closed. Behind the rubber pads are the screws. Find and remove all the screws holding the front plastic frame on the laptop lid. Keep track of the pads and screws as you will need them to reassemble everything.

Step Three. Remove the plastic frame from the LCD screen. Here is where you need to be careful. The screws are not the only thing holding the plastic frame on the LCD screen! The plastic frame is snapped into place. Carefully pry loose the frame from the LCD screen. Pry it loose gently. Try to keep it as close as possible to the LCD panel while you are prying it loose because you may also find that you need to slide it to the left or right to completely remove it from the laptop. There is a small protrusion of the plastic frame where the hinge is. Because of this protrusion you need to slide the frame, in this case, to the right, to detach it from the laptop.

Step Four. Locate and remove the screws holding the LCD panel to the laptop. These are located on the bottom. The screws are attached to a small metal hinge. this is the component that is attached to the keyboard frame.

Next you will need to remove the LCD screen. Note that there is a cable attached. This is the LVDS cable. It is best to take apart the rest of the laptop and unplug it from the keyboard. However, the cable can be cut at the bottom. Take care not to cut the two wires going into the inverter (that"s the slim circuit board at the bottom.

Once the LCD panel is removed, you can remove the LVDS cable and unplug the inverter at the bottom. Unplug the inverter from both ends. Do not cut it. The LVDS cable is taped to the back of the LCD screen at the top. It is the flat cable running up the back. Remove the tape and slid the cable down. Since you need to buy an LCD controller board, you will no longer need the LVDS cable the laptop came with or the inverter. At this point you should just have an LCD screen with a pair of wires coming out of it.

Keep track of the plastic front frame and the plastic backing. You will need them to resemble the LCD screen. On the other hand, you have different fingers, just kidding. On the other hand, you can buy a picture frame and put the LCD screen in the picture frame.

Here is a picture of the LVDS cable and the inverter detached from the LCD screen. Since we will be buying an LCD control board these cables will not be needed again.

Next, once you have removed the LCD panel. Flip it over and look for a model number on the back. You will need this model number to order the correct LCD controller board. I went to E-Bay and found one for $42.00. I bought the LCD controller board and then received an email from the seller requesting the model number of the LCD screen and manufacturer. This is because each controller board is flashed, (programed to run a specific LCD) I gave him my model number, LP171WX2 A4K1 and told him it was made by LG Phillips. Since the board was coming from China, I received my order about 2 weeks later. Due note to buy one with a power cord! The LCD controller board has the VGA input connection which allows you to connect it to another computer and use it as a second monitor or as a back up in the event the one on your working computer goes out.

The LCD controller board is real easy to connect. It comes with all the required cables, except a VGA cable which you will need, in order to connect your LCD to another computer. You can buy a VGA cable from Best Buy or a computer parts store.

The LCD control Bard comes with all the cables except the VGA cable which you will have to buy. Once you have received your kit, proceed to connect it to the LCD screen. Plug the LVDS cable into the LCD panel where you removed the original from. The two wires at the bottom of the LCD screen that were connected to the inverter need to be unplugged from the old inverter and plugged into the new inverter below. Then, plug the power in. Make sure that the LCD control board is not sitting on anything conductive, like metal or it will short and fry. Next connect the VGA cable to the LCD control board and plug the other end of the VGA cable to another computer. Make sure the computer is on before you plug in the VGA cable. At this point you should have the same image that is on the computer you plugged the VGA cable into, on the LCD panel.

Next, I attached a 4 inch section of two by four on the outside back of the laptop lid. I needed this in order to attach my stand to the LCD screen. I used 5 screws and screwed them in place from the inside. I did splice and extend the cables going from the LCD controller to the inverter it came with just to have a little more room.

Originally, I built a nice wooden stand for my LCD panel but was not satisfied with it. So, I took a broken florescent desk lamp and dremeled off the section holding the florescent tubes, leaving enough metal to screw on to the two by four on the laptop lid. Before attaching the stand, I drilled four holes in the metal to make it easier to screw it on the two by four.

Next you will need to attach the LCD controller to the laptop lid. To do this, screw in a few sections of wood from the inside of the lid. Then on the outside of the lid attach the LCD control board. Place the wood in an area where the control board can reach.

Next you will need to find all those screws you have been saving and reassemble the LCD screen. I also added some surgical tubing to the top springs for added strength.

By the way a store bought swing arm half the size of this one, I found, cost around $400.00. If you choose to use a swing arm like this one, go with the one that has a magnifier on it and dremel off the magnifier leaving enough metal to attach to your LCD lid. You need one of this caliber to hold the LCD screen. Swing arms with the light attached are not strong enough.

By the way, I did remove the web cam from the laptop lid, wired it to a USB cable, and turned it into and external peripheral. I wired the two microphones that I found next to the web cam and  turned them into external peripherals. I dremeled the batteries open and wired them into a 3 million candle power flashlight made from spare parts I had. I have a lithium ion battery charger, so it worked great.

Since I was asked about the web cam, I though Should add it to the instructable. There is a nice instructable here at this site showing how to convert a web cam from an LCD screen: http://rntmns.com/2011/02/rebirth-of-a-webcam/

Mine works great on my Vista laptop. If you want to use it for checking plumbing pipes, I suppose you can put a small prism on the web cam aperture so you can insert the web cam in a pipe and view images directly ahead--this would be good for archaeology where you need to investigate tight spaces.

I"m so glad I found this... I have a nearly identical HP laptop that you used and recently noticed that it was overheating and too much work to fix up, but the big beautiful display works great and I was sadly thinking I"d be better off selling it rather than dissecting the entire thing to fix its overheating issue.

Actually, you can do One better. You can salvage the RAM, the Wireless card, the Batteries, the charger, the hard drive, the DVD disk player and sell them to people that need them on E-bay and Still keep the LCD screen for yourself.

Genius! As an honorary "Red neck" (U.K. chapter, it"s a good thing, honest) I"m putting your application in the post. You have given me the three screens I need for my simpit plus a lot of peripherals that I hadn"t even considered. Thanks.0

Thanks for this instructable. I recently came upon some discarded laptops with either had bad screens or nonfunctioning everything else. I may be able to mix and match to get a usable machine out of the pile of junk!0

I checked ebay for the LCD control Board and all I did was punch in " LCD control Board for a LP154W01(A3)" , That"s my model number. You, of course, use your"s. ebay came up with the correct one for $25.00 and it has all the imputs you could want. This is good today, 2/11/19. Have fun folks!

i have a similar lcd panel to yours. infact 3 of them! they"re so easy to work with and doesn"t need a backlight controller LP154WH4 TLA1 except the lvds cable sold separately. I"ve build one and runs on

Nicely done and very informative!! However unfortunately, by the time you add the cost of the LCD Controller card, various parts and time you could have bought a new inexpensive monitor.

it really depends on what kind of display your laptop came with. I recently had a laptop that featured a 4k OLED screen and If I add the price up of the controller kit and materials (depending how you are going to make the stand) it would actually in my case be cheaper to make that an external monitor because, quite frankly 4k is pretty expensive and I don"t want to degrade to a lower resolution. in said laptop the motherboard died so I just scavenged everything including the LCD which I have just lying on my desk. so I might even consider trying this.0

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

Based out of Taiwan, Acer is known for some of the best-performing systems in the world. Though, there are times when even the best of laptops can malfunction. For instance, a lot of users complain about Acer laptop monitor not turning on and getting the Acer laptop black screen. If you have also got the Acer black screen of death, don"t worry – it is quite a common issue. In this troubleshooting guide, I"m going to tell you how to fix black screen on Acer laptop easily!

Since the Acer laptop black screen of death can be a crucial issue, users can end up resetting their system to fix it. In that process, you might end up losing some of your important system or user files. Therefore, what you should do first when your acer laptop screen won"t turn on is restoring and making a copy of your files and documents. You can use a reliable recovery tool like

The creation of a bootable device will start. During the process, please do not remove the USB flash drive. As the creating process takes a while, please wait until the bootable drive used to boot your acer laptop up is created.

Adjust BIOS to boot from USB, allowing Acer computer to boot through your bootable device. Restart your crashed Acer laptop and press the BIOS entry key when the first screen is displayed.

If you are getting the Acer computer black screen even when the system is turned on, then you can try the following fixes after backing up your data. Since it can happen due to hardware or software-related reasons, you need to follow a stepwise approach to fix this.

To start with, I"m going to list the simplest way to fix the Acer Aspire black screen problem. If there is a minor issue with its firmware or booting, then you can try to power reset your laptop. To do this, just press the Power button on your laptop and keep holding it for at least 15 seconds.

If you have got the Acer black screen, then you first need to check whether the issue is with the screen or caused by a firmware problem. For this, I would recommend connecting your system with an external monitor. You can use the connecting cable and simply fix it with an external monitor. If you get the correct display on the external monitor, then it means the problem is with your laptop"s screen (and not its firmware).

Step 3. If an image displays on the external monitor, the reason might be a graphics driver conflict with the laptop LCD display. So solve this, you need to install the latest graphics and chipset drivers for your specific computer.

Another smart solution to fix the Acer Chromebook black screen of death includes the use of function keys. You might already know that there are certain functions and special keyboard shortcuts that we can use for different purposes.

Sometimes, even a driver-related issue can also cause the Acer computer black screen problem. For instance, if the driver has become corrupt, is outdated, or has not been installed properly, then it can make your Acer laptop go black screen after the logo. To fix it, you can consider reinstalling or resetting the graphic card driver.

Chances are that a virus or malware attack on the system"s disk could have also resulted in the Acer laptop black screen. For instance, it could have corrupted the disk or the Windows partition, leading to the malfunction of the system. To fix the Acer Aspire black screen, you can use a reliable anti-virus software like Windows Defender or a third-party tool from brands like Norton, AVG, Avira, Avast, Kaspersky, etc.

BIOS, which stands for the Basic Input and Output System, is responsible for the overall booting operations of the system. Though, if there is an issue with your BIOS program, then it can cause the Acer black screen of death. In this case, you can consider updating your system"s BIOS settings by following these steps:

That"s it! Once the BIOS settings have been upgraded, your system will automatically be restarted. If the Acer laptop black screen occurred due to a corrupt or outdated BIOS, then it will resolve the issue.

It might sound surprising, but the Acer black screen of death can also happen due to a discharged system. If the AC adapter or the battery of your Acer system is not functioning, then you might not be able to turn the laptop on. Firstly, you can check the adapter by connecting it to any other device. Also, you can remove the battery of the system and get it checked to ensure there is no serious hardware issue with the system.

Once the battery is charged and the AC adapter is fixed, you can connect them back to the system and turn it on. By the way, you can learn more fixes on Windows 10 black screen.

If the memory module is loose, it usually causes the laptop to not display images. Therefore, reinstalling the memory module may solve the problem of black screen or black screen on the laptop. You can finally do this by removing the AC adapter from your laptop, removing and relocating the memory stick, and then reconnecting the AC adapter to your laptop.

Step 1.Close your laptop, then disconnect the power cord. Contact a grounded metal object to release static electricity before performing any operation.

• Perform highly diversified duties to install and maintain electrical apparatus on production machines and any other facility equipment (Screen Print, Punch Press, Steel Rule Die, Automated Machines, Turret, Laser Cutting Machines, etc.).

Depending on the age, model, and operating system of your laptop, you have several options to diagnose your issues and figure out the next steps to get your laptop working well again.

If your laptop won’t hold a charge, won’t charge fully, or won’t charge at all, you could need a new battery. Battery life for a laptop is around two to four years, although how you use and charge it will determine its useful life.

This repair is among the simplest for most laptops and only costs as much as a replacement battery, although a few laptop models may not let you open the battery compartment and will require you to ship the laptop to the manufacturer for repair.

If the indicator light doesn’t come on when you connect your charger to your laptop or it does but only when you hold the charger at a particular angle, you could also have a broken laptop charging port.

Charging port repairs do require you to have an expert open your laptop and make the repairs internally, but it is usually a quick job for them so parts and labour costs should be reasonable.

If your laptop randomly turns off in the middle of a task, it could be a battery issue. Check to be sure your laptop is plugged in and charging, then turn it on after it’s had some time to recharge.

It may also be a screen error. If you hear your computer running but there is nothing on your monitor, restart your laptop and see if it happens again. If you’ve discovered it isn’t any of these issues, you may have a hard drive failure. In most cases, this is a symptom of a larger, more complicated problem.

Make a backup of the data and programs on your laptop as soon as possible and take the laptop to a professional for inspection and laptop repair service before you lose what’s stored on your device.

Windows-based operating systems have measures in place that will shut down your computer before major issues happen, such as a complete breakdown of your hard drive. It will usually warn you by showing a blue screen with an error message.

Because these error messages are somewhat ominous and can warn you that it’s a major issue with your operating system, hard drive, or computer components, it has been dubbed the “blue screen of death.” While it can happen once or twice without consequence, it’s typically the sign of a larger issue.

Read the error message in full when this happens and use the Windows-based troubleshooting software that pops up on the blue screen to perform a system recovery or restore it to an earlier point.

When is the last time you ran basic maintenance on your laptop? If you’re like most people, it’s been too long. Go to the Windows search bar or ask Cortana about “system maintenance.” You’ll be prompted to perform a set of tasks right away or schedule them for later.

These include disc optimization tasks, which will free up space on your hard drive and store your files more efficiently. You can also try this list of ways to tune up your PC - it works for laptops as well as desktops.

Also, try to pinpoint what programs are giving you issues. If you only experience lag when using a web browser, you may need to update the browser to the most recent version, or you could have too many cookies and temporary files stored on your laptop.

Finally, make sure your desktop is clear of the dozens of files and folders that accumulate there because this uses precious memory and can cause bad laptop slowness.

Move them to the documents, photos, or videos folders, or delete them altogether. If these fixes don’t work, it’s time to take your laptop to a computer repair pro.

All laptops get a little warm by design, and it’s advised that you don’t use them directly on your lap. If you are using a lap desk or other safe surface and you can still feel the heat, take a moment to cool down your laptop by turning it off, disconnecting the power cord, and performing a quick check.

Does your internet keep dropping while you’re using your laptop? Are you continually needing to find your home network or re-input the network key? Does your Bluetooth speaker not recognize your laptop?

Before going in for laptop service and repair, try troubleshooting your wireless router and ensuring it’s not a problem with your network. Other devices shouldn’t be able to connect if it’s a wireless problem.

If other devices are working properly, use your laptop’s “identify and repair network problems” feature by asking Cortana or searching in the start bar on your laptop.

You’ll be guided through a repair sequence that may restart your computer’s wireless adapter or ask you to make changes to your settings. If this doesn’t fix your problem, you will be prompted to take your laptop in for repair.

If your laptop doesn’t sense your typing, several things could be to blame. First, see if it’s only numbers that aren’t working because pressing the “num lock” key accidentally may keep you from using the keypad. Press it again to resume numerical input.

Computers are an essential part of our modern lives. Be it a custom-built PC or a personal laptop, they provide seamless solutions for many of our needs, like online shopping, web-based classrooms, virtual meetings, and so much more.

That said, many forget that computers require regular ‘check-ups’ too, done mainly by undergoing scheduled scans or running performance-based apps to evaluate their overall condition. Though some might take this lightly, a compromised computer will not work as efficiently as before and, in certain cases, can lead to the dreadedblack screen of death.

Simply put, a black screen of death is when acomputer is stuck on a blank, black screen. The commands or button prompts do not work, and the PC becomes unresponsive.

In worst-case scenarios, constantly forcing a computer to shut down can lead to file corruption or hardware damages, which are primary indicators for you toconsider buying a new laptop/desktop. Other minor issues can also occur, but different factors cancause computers to slow down, so a complete system diagnostic is usually the best way to identify problems.

If your computer consistently freezes at a black screen, you should identify the main issues immediately before any long-term harm can be inflicted on your PC.

Most of the time, a computer black screen occurs due to recent changes made to the PC. Check if it’s one of the following reasons that’s making your laptop screen black:

Sometimes, a black screen occurs due to an interrupted connection between the computer and its display monitor. This often happens to desktop users accidentally dislodging the cable from its proper port, either on the computer case, the monitor itself, or both.

A faulty display device or video adapter can also prevent a computer from displaying images, prompting a black screen. This is often the case when the PC produces sounds normally but cannot project any visuals.

Adisplay device is an external apparatus that produces visual output, such as an LCD monitor. On the other hand, avideo adapter is dedicated hardware- such as a graphics card - that creates those images before sending them to a display device.

A complete system update or new software installation can also force a black screen error. This usually happens due to conflicting commands or coding that might disrupt the computer’s main programming, interrupting some critical processes as a result.

The ideal fix can be applied by identifying the most likely causes of the computer’s black screen prompt. This is important because some fixes require tweaks to be made to the computer’s system, including the BIOS (Basic Input/Output System), depending on the issue.

Consider external causes first, such as a damaged display cable, before exploring technical possibilities. With that in mind, here are some possible ways for you to resolve a frozen black screen on a computer:

If the computer freezes at a black screen again, the last resort is to forcibly shut down the PC by pressing and holding the computer’s power button for around 10 seconds.

If it’s still stuck on an empty, black screen, acomputer restart inSafe Modewill be required to safely revert the display adapter’s driver to a previous version.

After a couple of forced shutdowns - due to failure to boot up properly after getting stuck at a black screen - the computer will automaticallyenter itsAutomatic Repairphaseduring the next restart.

After failing to start multiple times, the desktop/laptop will automatically enter theAutomatic Repairscreen on the next boot up/restart from a manual shutdown.

It is hard to know which black screen fix is the right solution for your PC without identifying its probable causes first. In certain circumstances, users might even be forced tomake changes inside the computer’s BIOSinstead, which can be intimidating for some.

Acomputer boot by using a USBcan also be performed, especially if the PC still fails to resolve its black screen issue. However, it might be best to consult a professional technician to avoid risking damage to the computer.

I have a Toshiba R950 with a faulty LED blacklight. The screen is very dark and you can see text when you use a strong light. So it is a blacklight problem. I have ordered a screen from china, with a higher resolution, but same 40 pin and almost the same screen model number. The blacklight was working, but the screen was green and blurry. I swapped the china screen with the old one, the old one has still no blacklight. After swapping once again, the china screen also has no blacklight anymore! I have ordered the same screen as the original from the Netherlands, but it has also no blacklight. So I have 3 screens with no blacklight. What can be the problem? I think it is maybe the invertor, but that is mounted on the screen, so I don"t know.

Yes. If the type-C port of your laptop can supply over 5V2A power, then you can light up the whole two screens of the Kwumsy P2 PRO&P2S laptop screen extender.(Note:Please make sure that your laptop has full function type C port which support power,data transmission and display,such as thunderbolt3 and thunderbolt4).

Use the Kwumsy P2 PRO&P2S laptop screen extender is to plug one end of the cable into the full-function USB-C port on your laptop and then plug the other end into the "Type-C" port on the Kwumsy P2 PRO&P2S laptop screen extender.

① P2S only supports laptops withWindows operating system(NO need to install drivers), P2 PRO supports laptops with Windows and Mac operating systems(Need to install drivers).

③ P2 PRO can realize USB-C to USB-A or USB-C to USB-C connection, while P2S can only have USB-C to USB-C connection. So make sure your laptop has at least one USB-C port.
