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.

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.

A laptop that does not boot is always a source for concern and even panic in some cases. If you are like many people, your laptop not only serves as a source of entertainment, but also as a repository for important data and documents. Therefore, if your laptop turns on, but is not able to display anything on the screen, anxiety runs high – to say the least. If your laptop is still under warranty, contact the retailer or manufacturer immediately and ask for assistance. If your laptop’s warranty has expired, though, use a few simple steps to troubleshoot the notebook and determine whether you can repair the unit yourself.

Shut down the laptop and close the LCD screen. Remove the AC power cord and other cables from the laptop. Flip the laptop over and remove the battery pack.

Use an eraser to clean the metal contacts on the battery and the battery bay. Remove any tarnish or build up that may appear on the contacts. Blow the excess eraser bits from the battery and the battery bay.

Reinsert the battery into its bay and reconnect the AC power cord and other cables. Ensure that the cable connections are tight and that you lock the battery in its bay.

Locate the cover for the memory module. On most laptops, the memory slot cover has a small icon picture of a memory stick or label. Remove the screw that holds the cover in place with the Phillips screwdriver.

Locate the hard drive cover and remove the retaining screw. Remove the hard drive and reseat it in its slot. Do the same for the CD/DVD drive of your laptop.

Connect the monitor cable from a spare external monitor to the VGA or DVI video out port on the rear of the laptop. Plug the power cord into an available electrical outlet.

Power on the laptop. After the LED lights on the laptop appear, or you hear the hard drive inside start to spin, press the “Fn” key combination that sends the display to an external monitor. On most laptop keyboards, there is a small icon picture of a monitor symbol. Press the “Fn” key and the key with the monitor symbol a couple of time to see if an image appears on the external monitor. If an image appears on the monitor, the problem is with the LCD screen of the monitor. If no image appears on the monitor, either the video card or motherboard in the laptop is probably defective.

Just like televisions, laptop displays start to flicker too after a few years. You may sometimes also notice the display turning blank even when the laptop is on. Alternatively, you might find some white lines running down the display.

This doesn’t necessarily mean that there is an issue with the motherboard. If your laptop keeps turning off every few minutes and doesn’t turn on, there is a high chance that the AC adapter has malfunctioned. You can get help from a professional to confirm and get the AC adapter replaced, if required. There is also a possibility that the DC power jack may have broken. A DC connector (or DC plug) is an electrical connector that supplies steady power to the device.

If the DC jack has broken, you can try adjusting the plug’s angle in its jack. If you see some lights turning on but the device is still not booting, it’s time to replace the DC jack. If that doesn’t help, it’s a clear indication of a motherboard-related issue. You can either get the motherboard repaired or replaced by the brand service center. Getting the motherboard repaired could cost you anywhere up to Rs 10,000, whereas the cost of replacing the motherboard can go anywhere up to Rs 25,000.

If you ever notice multi-coloured or single-coloured vertical lines on your laptop screen, it may be a result of a hardware failure or due to damage to the screen. To try fixing it yourself, first unplug your laptop, hold the power button for 30 seconds and restart the laptop. If you continue to see coloured lines, the issue is probably with the LCD screen, which will need to be replaced from the brand’s service center. To be sure about the LCD screen problem, try connecting your laptop to another monitor and see if the issue persists. If it does, the issue is certainly in the LCD panel.

On turning on the laptop when you see the lights blinking and hear the fan working but if the laptop screen is blank and doesn’t display anything, this is again an indication of a faulty motherboard. The first thing to do is to transfer all the data to another drive to make sure your data is safe. Before going ahead and getting the motherboard repaired or replaced, you could try performing a hard reset (also known as a factory reset), which can mostly help in resolving the blank display issue.

Firstly, check if your laptop’s brightness level is set to maximum. If the display is still dim, try restarting the device. This could just be a system error that can be resolved by restarting the device. Also, check if the AC adapter cord is loose and firmly connect it to the outlet and laptop. If the issue still persists, it is mostly due to a failure of the LCD. Behind the LCD, there is an inverter board and backlight bulb which control the picture.

The inverter board converts the low voltage your laptop uses, into higher voltage required by the long bulb that lights up the LCD screen. If the inverter board or bulb fail, you will experience the problem of a dimmed display. Even if one of these two components fail, the screen will need to be replaced, unless the service center can help by just replacing the bulb. We wouldn’t recommend you try resolving it yourself, as this is more complex and you could end up damaging the circuit board and the backlight lamp. So, it’s best to leave this job to an expert.

Laptops are fragile and can easily break, especially with more and more thinner and lighter models being launched now. Some of the most common ways how a laptop is damaged include: when it accidentally falls and the screen cracks, when it’s held at an awkward angle or if you unknowingly placed something heavy on the laptop. Remember, a cracked laptop screen can affect the overall functioning of the device in some cases.

Since brands do not cover the laptop screen, it’s best to get your device covered with a protection plan in advance. Screen replacements are expensive and can cost you anywhere up to Rs. 15,000 but if you have the

When the screen blacks out, shine a torch at an angle close to the screen to see if you can detect if a display is still there. It will be dim but a darkened room will help.

This can be caused by (depending on laptop model, you didn"t say what model you have) a faulty backlight power inverter, faulty backlight power cable, faulty lid switch, faulty video cable or faulty screen.

If the external monitor display stays on, then you either have a faulty video cable, faulty video cable connections at either end (motherboard or screen) or a faulty screen.

If the external monitor display also turns off then you have a faulty GPU or motherboard (which is basically the same thing as the GPU most probably is mounted directly onto the motherboard.

If you can still "see" the display when the screen goes black it indicates that there is a problem with either the voltage level of the power supply to the backlighting going intermittently faulty or that somehow the connections supplying the power are going more resistive (as best as I can determine the power from the backlighting is supplied from the motherboard and not a separate inverter board in the laptop).

Just wondering if it could perhaps also be a problem with the software control of the backlighting. When the screen dims have you tried pressing Fn + F6 together to see if you can increase the brightness at all?(Fn + F5 dims the screen)

Here is a link to a webpage that shows how to dis-assemble the laptop. It may help if you wish to see if there is anything obvious such as a loose video cable connection etc on the motherboard Unfortunately it doesn"t show how to dis-assemble the lid to view the screen end.

As I cannot find a service manual online, without a schematic diagram it will be difficult to ascertain where exactly the problem is. It may be that you will have to contact a reputable, professional laptop repair service and ask for a quote to repair the laptop

In PC-related forums, we can see there are a lot of users who ran into the issue of "Computer starts but screen remains blank". However, not many people know quick and effective ways to fix this.

Don"t worry. In this post today, I will show you not one but several suggestions that may help you get rid of this annoying "Computer turns on but no display on monitor or keyboard" issue. You can try each of them until you get rid of the error.

If your computer starts but the screen is black, you should first make sure your monitor is working properly before you begin more complicated and time-consuming troubleshooting.

It"s possible that your computer is working fine and your monitor is the only problem. If not, keep reading to find other solutions to fix this issue.

Sometimes, your computer will appear to "not be on" when it"s just having problems resuming from either the Standby/Sleep or Hibernate power saving mode in Windows, resulting in your computer is turned on but having no display on the monitor or keyboard.

Tip: While in power saving mode, you can hold the power button down for 3 to 5 seconds to completely power off this computer. After that, turn on this PC to check whether it can boot normally.

If the input voltage for the power supply is not correct (based on your country), the issue of “PC turns on but no display” may occur (You might be interested in this post: What Is a Power Supply Voltage Switch?)

If this switch is wrong, maybe your PC wouldn"t power on at all. Therefore, an incorrect power supply voltage might prevent your computer from starting properly.

If your computer is still having no display even after checking the monitor and verifying that your PC has full power cycled, you can try booting into safe mode and then repairing Windows either using System Restore/Automatic Repair or resetting your computer.

However, sometimes, Windows Automatic Repair not working issue will happen. (For more details about this issue, please check this post: How to Fix "Windows Automatic Repair Not Working"). Thus, most users will try resetting the PC. Resetting is usually a "magic" fix to problems like the PC turning on but no display.

Tip: If this method solved your issue - the computer starts but the screen remains blank, make sure any future changes you make in BIOS are completed one at a time so that when the problem returns, you will know which change caused the issue.

Now, you can try resetting the memory modules to fix the "PC turns on but no display" issue. Remove the memory module from the memory slot, and then put it back into the slot to get a better connection so that the computer can recognize the memory.

If your computer beeps and does not start, there might be a more serious hardware issue. Now, you"ll probably need to seek professional help from a computer repair service or your computer manufacturer"s technical support.

Try disconnecting all devices and peripherals like the mouse, external hard drive, speakers, printers, scanners, etc. from the computer. Then, try turning on your computer again.

Sometimes, the VGA/HDMI port on the computer could be damaged or bent if a cable connected to it wasn"t properly taken out. Additionally, some people might try to connect a cable to a connection that doesn"t match, which can also end up damaging the gold or silver connectors inside the port.

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.
