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

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.

There are many reasons why this can happen, usually due to system errors that conflict with the protocols of a computer’s operating system (OS), causing it to malfunction. This forces a hard PC shutdown, which might affect its health if prompted too often.

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.

In Automatic Repair, users can also reset the computer to its basic state or opt for other repair actions instead of System Restore, such as Startup Repair or System Image Recovery, if necessary.

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.

Prevention is always better than cure, so be careful when downloading third-party files or apps that might seem suspicious. If possible, always install new programs directly from the official source, and back up your computer regularly to safeguard important folders from being corrupted.

Test your monitor. Before you begin more complicated and time-consuming troubleshooting with the rest of your computer, make sure your monitor is working properly.

With the monitor disconnected from your computer, turn it on and off. If the display shows diagnostic information of any kind, you know the display is powered and is capable of displaying content.

Verify that your PC has completely restarted and is powering up from a completely powered off state. See how to restart your computer if you need help.

A computer might appear to "not be on" when actually it"s just having problems resuming from either the Standby/Sleep or Hibernate power saving mode in Windows.

Power off your computer while in a power saving mode by holding the power button down for 3-5 seconds. After the power is completely off, turn on your PC and test to see if it will boot normally.

Clear the CMOS. Clearing the BIOS memory on your motherboard will return the BIOS settings to their factory default levels. A BIOS misconfiguration could be why your PC won"t start up all the way.

If clearing the CMOS does fix your problem, make sure any changes you make in BIOS are completed one at a time so if the problem returns, you"ll know which change caused your issue.

Verify that the power supply voltage switch is set correctly. If the input voltage for the power supply isn"t correct, then your computer might not turn on completely.

There"s a good possibility that your PC wouldn"t power on at all if this switch is wrong, but an incorrect power supply voltage might also prevent your computer from starting properly in this way, too.

Verify that all the cables are connected correctly. For example, if the onboard video card has been disabled, plugging a VGA cable into it will result in nothing on the monitor even if the computer is powered on. In this case, you"d want to plug the VGA cable into the correct video card.

Test your power supply. Just because your computer"s fans and lights are working doesn"t mean that the power supply is functioning properly. The PSU tends to cause more problems than any other hardware, and is often the cause of a computer"s components to work selectively or intermittently.

After replacing the power supply, assuming you do, keep your PC plugged in for 5-10 minutes prior to turning it on. This delay provides time for some recharging of the CMOS battery, which may have been drained.

Do not skip a test of your power supply, thinking that your problem can"t be the PSU because "things are getting power." Power supplies can work in varying degrees—one that isn"t fully functional needs to be replaced.

Start your computer with essential hardware only. The purpose here is to remove as much hardware as possible while still maintaining your PC"s ability to power on.

This step is easy enough for a novice to complete, takes no special tools, and could provide you with a lot of valuable information. This isn"t a step to skip if, after all the steps above, your computer is still not turning on completely.

Since your computer powered on with only the essential hardware installed, those components must work properly. This means that one of the hardware components you removed is causing your PC to not turn on properly. By installing each device back into your PC and testing them each time, you"ll eventually find the hardware that caused your problem.

Test your computer"s hardware using a Power On Self Test card. If your PC still isn"t displaying information on your monitor with anything but essential computer hardware installed, a POST card will help identify which piece of remaining hardware is causing your computer to not come on completely.

Replace each piece of essential hardware in your computer with an identical or equivalent spare piece of hardware that you know is working, one component at a time, to determine which piece of hardware could be at fault. Test after each hardware replacement to determine which component is defective.

If you don"t have a POST card or spare parts to swap in and out, you"re left not knowing which piece of your essential PC hardware is faulty. In these cases, you have little option than to rely on the help of individuals or companies that do offer these resources.

In Windows operating systems, problems with display and graphics are usual. This time we will introduce you to the issue – laptop white screen on the MiniTool website. How to fix white screen on laptop? A couple of solutions for this strange issue will be introduced to you.

When you start up a laptop from Lenovo, Dell, Acer, etc, you may find there is an appearance of a white screen and the laptop can’t boot to the login screen, which is annoying since you couldn’t use the laptop properly. The laptop white screen problem may be caused by a faulty graphics card, non-working display, malware/viruses, etc.

Tip: In addition, you may also be bothered by the white screen on computer monitor if you are using a desktop PC. The solutions are similar to a laptop’s.

To figure out if it is a broken laptop display, you can connect your laptop to an external display. If the issue still appears, it is not the problem with your laptop display.

If the laptop screen goes white as soon as you press the Power button, it is obvious that your graphics card goes wrong. So, you should consider a replacement.

This method appears to be easy but it is really useful. According to some users, many screen problems can be solved by simply removing the battery and restarting the PC again.

Some users said that the laptop white screen problem can happen if the malicious software starts along with the Windows system. To remove the malware from your system, use a third-party anti-malware program and scan your computer, for example, Malwarebytes.

Since you are not able to run Windows normally when getting the white screen on computer monitor, it is necessary to go to safe mode by following the steps.

If your Windows has some system-related problems, then the laptop screen goes white. So, you can perform an SFC scan to deeply scan and fix your computer for errors.

Similarly, you need to do this in safe mode since the PC is unbootable. In safe mode, run Command Prompt with admin privilege and then perform the sfc /scannow command.

Have you been bothered by the laptop white screen issue in Windows 10? How can you fix it? Read this post and try one of these methods above. Hope that at least one solution is helpful for you.

A black screen on MacBook Pro can be terrifying, and if it ever happens, it tends to be at worst time. We consider Apple MacBooks to be among the best laptops for creatives, and part of the reason for that is that we find them to be so reliable. But like with any laptop or desktop computer, sometimes problems can occur.

MacBook Pro black screens can occur in several forms, and it"s not necessarily a cause for concern. You"ll normally see a black screen on MacBook Pro (or a grey or blue screen) at least once during startup, and sometimes the process can take longer than others, especially if it"s been a while since you"ve used your device. If you"ve waited, and you"re still seeing a MacBook Pro black screen after a few minutes, it"s time to try to a few things that might solve the issue.

Before you start wondering how much it might cost to fix, take a breath and try working through the steps below before you visit your nearest Apple Authorised Service Provider or store. Many of our writers and creative contributors use MacBooks for their daily work, so a black screen on MacBook Pro is an issue we"ve come across in the office more than a few times. Below, are the steps that we go through to try to solve the problem, whether it involves the laptop"s own screen or an external display.

Speaking of external displays, if you"re looking to expand your screen space, see our choice of the best monitors for MacBook Pro or the best 4K monitors. And If you"re looking to upgrade your laptop, see our pick of the best MacBook Pro deals.

Whether your using an older Intel MacBook or a brand new M2 MacBook Pro, any number of issues can cause a MacBook Pro black screen. Sometimes it can happen waking your laptop from sleep, and sometimes it can be caused by broke disk permissions or a software error. Below we"ll outline the steps to try if the problem is a black, or otherwise blank screen, on your MacBook Pro"s own display. If your problem is with an external monitor, skip to how to fix a black screen on a MacBook Pro external monitor.

This might seem obvious and you"ve probably already done it, but just to be sure, do check the power and brightness controls. It can be a massive relief to discover the issue is something as simple as this. If you"re running on battery, connect your laptop to its charger just in case the battery has run down. Check the power indicator light shows so you can rule out a faulty power cable. It’s also possible that you (or your cat) might have unintentionally hit the brightness keys on the keyboard at some point at that you screen is simply dimmed. Hit F2 or use the control bar to try increasing the brightness on your MacBook Pro.

Peripheral devices like printers, keyboards, external drives, mice and trackpads can all cause potential start up problems. If you definitely have power, but your MacBook isn"t starting up, make sure it"s disconnected from anything other than your charging cable and adapter.

Once you"ve confirmed that the laptop is receiving power and you"ve ruled out the possibility of interference from peripheral devices, the next thing to try is a simple restart. Pressing Control + Command (the symbol with four loops) + Power/Eject/Touch ID button(depending on your model) should automatically restart your device. Alternatively, hold the power button for 5 seconds to shut down your MacBook Pro, wait 15 seconds and then press the button again to reboot. Fingers crossed.

Still no luck? Then try a forced reset and then start up from macOS Recovery. Sometimes a good old-fashioned hard restart is all it takes to fix all kinds of MacBook issues. On an Apple-chipped MacBook Pro (from the M1 MacBook Pro 13 to the new 2023 M2 Pro and M2 Max models), press and hold the power button for about 10 seconds.

You should see the startup options window, which includes a gear icon labelled Options. Select Options and Continue. If the options window doesn"t appeal, release the power button, and press and hold it again for another 10 seconds. If the startup options window doesn"t appear, release the power button and try again.

On an older Intel-chipped MacBook Pro, press and hold the power button for about 10 seconds, then press and release the power button and immediately press and hold Command + R until you see an Apple logo or other image. If you still see a blank screen after about 20 seconds, it"s time to move on.

In both cases, if this recovers your screen, it"s worth running Disk Utility to check for errors. If Disk Utility finds errors and repair them, restart your MacBook again afterwards. If it finds no errors, Apple recommends reinstalling macOS(opens in new tab).

This isn"t official from Apple, but years of MacBook lore claim that a particular key sequence can sometimes revive a non-reacting blank MacBook Pro screen. Press power button once, Press "S" (the sleep hotkey), and then hold the power button to perform a hard shut down. Wait 15 seconds and press the button to restart. We have no idea why this works, but plenty of people have vouched for it.

MacBook Pro Safe Mode allows you to start you MacBook without other launch agents booting up. This can eliminate the potential for issues with other apps and services interfering and preventing your screen from displaying correctly.

To boot into Safe Mode, power off and let your MacBook Pro sit for 20 seconds. Turn it on again and immediately hold down the Shiftkey. Release the Shift key when the login window appears. You should see "Safe Boot" in the upper right corner of the window. Sometimes you may be asked to login twice, and your computer may take a longer than usual to start while it carries out diagnostics. After it"s completely booted up, you can restart again in normal startup and see if the black screen is fixed.

If that doesn"t work, it"s time to start turning to more technical solutions. NVRAM (non-volatile random-access memory) and PRAM (Parameter RAM) are small memory partitions that store settings like volume control and display resolution. Sometimes they encounter issues and require resetting. To do that, power down then hit the power button again to boot up you MacBook. Immediately hold down Option + Command + P + R at the same time while the machine boots, and keep holding them down until you hear the startup chime (around 2 seconds)

Note that you may lose some of your settings by doing this, so if this does solve the issue, check you system preferences afterwards to make sure your date/time, display and disk options are correct.

The Mac"s Systems Management Controller (SMC) controls things like temperature, keyboard, display and fans. Resetting the SMC is another possible quick fix to resolve a black screen on MacBook Pro. Turn of your MacBook and unplug it for at least 15 seconds before plugging in again. Then, with the power still off, hold down Shift + Option + Control + the power button all together. Release the keys when your MacBook starts booting up.

As a very last resort you may need to reinstall MacOS, but note that this will mean effectively reverting to a new Mac. You may want to contact Apple Support(opens in new tab) before resorting to this. While you can non-destructively reinstall macOS without deleting files, we recommend always backing up your files and folders to an external hard drive or to the cloud in order to be prepared for this eventuality.

The steps above should help you resolve a MacBook Pro black screen, but if your laptop"s own screen is working but an external monitor is blank, there are other things to try.

It may seem obvious, but first check the power on your external monitor and then check you connections. Most MacBook Pros only offer Thunderbolt/USB-C connectors for external monitors, so if you"re using a monitor with a different connection, you"ll need to check your adapter or dock too. If you find that the external display doesn"t turn on after you connect it, try connecting your display while your MacBook is turned off, and then switch your MacBook on.

The black screen on a MacBook Pro external monitor may be caused by simply closing your laptop. By default, this automatically puts your MacBook Pro to sleep. If you want to be able to close the lid of your MacBook Pro but still use the laptop via an external monitor, you"ll need to change some settings. Go to System Preferences > Battery > Energy Saver > Power Adapter, and move the slider to Never. Note that you"ll also need to have a keyboard and either a mouse or trackpad connected to your MacBook Pro or it will still sleep on closing the lid.

If the external monitor display is still blank go to System Preferences > Displays. You can press the Alt/option key to bring up the "Detect Displays" button. Click on "Detect Displays", to prompt your MacBook Pro to recognise the external monitor. See our guide to how to connect a monitor to MacBook Pro for more details on using an external monitor and see our guide to the best dock for MacBook Pro to expand your connection options.

In the above we"ve dealt with how to fix a MacBook Pro black screen when the screen is showing nothing at all. There are other issues that can occur, for example, the screen may flash a question mark, a circle with a line through it or something else. These are all signs that your MacBook it powering on but isn"t starting up:

A circle with a line through it: this means that your startup disk contains a Mac operating system but you"re not able to use it. Apple recommends that you press and hold the power button on your Mac for up to 10 seconds until your device turns off and then use Disk Utility to repair your startup disk (see above).

A folder with a flashing question mark: this means that your startup disk is no longer available or doesn"t contain a working Mac operating system. Apple recommends that if the question mark is persistent and your Mac isn"t starting up, again try pressing and holding the power button for up to 10 seconds until your Mac turns off and then using Disk Utility to repair your startup disk. If it doesn"t find any errors, you may have no option but to reinstall macOS.

Lock icon: If your Mac is using a firmware password, the lock icon will appear if you try to start up from another disk or volume, such as an external drive or macOS Recovery. You"ll need to enter the firmware password to continue.

Apple logo and progress bar: If the startup process stalls on the Apple logo or progress bar, press and hold the power button for up to 10 seconds until your Mac turns off, and then turn it back on. If the issue continues, turn it off again and unplug all non-essential accessories. If that doesn"t work, try repairing the disk using Disk Utility or reinstalling MascOS from MacOS Recovery.

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

Notebook computers squeeze a long list of parts into a minuscule amount of space. Their video cabling can run through casework hinges and around monitor bezels, tracing a complex path from motherboard to screen. Any disruption of this critical wiring can cause equivalent interruptions in your computer"s on-screen display. Some of the symptoms of incomplete video connections also can point to other hardware failures. Correcting these problems can be as complex as diagnosing them.

Black or Blank Screen Even with loose or disconnected video cabling, some laptops continue to boot -- minus on-screen display, of course. When you start up an otherwise properly functioning notebook computer, you hear and see a sequence of sounds and indicator lights that proceeds regardless of whether your screen responds correctly. If your screen stays dark but your system makes its normal noises and displays no unexpected blinking lights, your video cable may not be making contact. To verify that the computer"s on-board video functions remain intact, plug an external monitor into the laptop"s video-out port and restart. These symptoms also can accompany a failure of the fluorescent or LED backlight system that illuminates your display panel.

Intermittent Video Function Loose cabling can produce intermittent disruptions of video function, especially if you nudge the notebook system or its display panel while the computer runs. These kinds of positional interruptions can plague any form of electrical connection that"s not completely plugged in or that suffers from pinched or broken wiring in a faulty cable. Because these symptoms can signal damaged as well as loose connections, they may require new parts. If your computer remains under warranty coverage, contact its manufacturer for assistance.

Garbled Display Problematic video cabling can distort or interfere with on-screen display of your operating system and applications. You may see blank areas, unexpected horizontal or vertical bands of color, or other flaws that also can materialize on a faulty or damaged display panel. Diagnosing these malfunctions can require tools and disassembly skills that exceed the capabilities and resources of the average computer user. To isolate the problem, look for service under warranty coverage or independent technician assistance.

Other Considerations Many symptoms of laptop video display failure can trace to more than one potential cause. The diagnostics involved in troubleshooting video components and connections can require complicated disassembly procedures, diagnostic tools and access to replacement parts. Unless you have the necessary experience, reference guides and equipment to tear down, repair and reconfigure your system successfully, trying to fix your computer yourself can cause more problems than you solve. Weigh the age and replacement value of your laptop against the cost of repairs before you try to find and fix what"s broken.
