7 Ways to Turn Off Windows 10 Laptop Screen
For better or worse, we don’t live in 1999 and most monitors don’t have a screen off button. over, I’ve never seen a laptop with a separate button to turn off the screen.!
But don’t worry, there are many ways to turn off the screen on a Windows 10 computer or laptop. Here are 7 of the easiest and fastest methods.
Why the laptop slows down
Very often, while working at the computer, the operating system starts to slow down. As a result, the laptop may freeze completely. This can happen for several reasons, namely:
- NOT enough RAM;
- Overflowed processor;
- System malfunctions;
- The presence of viruses on the PC;
- OS is not loaded correctly;
- OS settings are out of order.
To fix these problems, it is often enough to expand the RAM or roll back the system. But in any case, you will have to turn off your laptop first.
If all of the above methods failed to help you, there is another option. To turn off the laptop you need to disconnect the charger, find the battery on the back of the computer and remove it. Then put the battery back in place.
Now you can start the laptop again. Not every laptop can use this overloading option. In those devices where the unit is not portable The described method is not relevant.
How to turn off a laptop if it freezes
Almost all users face this problem very often. Unlike a desktop computer, several methods can be used to restart a laptop. Often, they all have certain consequences for the operating system. The following will describe the maximum possible safe methods for overloading the PC.
If the laptop stops working
When your PC has stopped responding to any actions, a forced restart can help. To do this, do the following:
- Hold down the CtrlAltDel keyboard shortcut.
- In the window that opens from the bottom of the case, you will see the shutdown button, and next to the key with the arrow, which must be pressed.
- In the pop-up menu, click “Restart”.
This option will help you when a black screen appears and you cannot use the first method.
There are situations when the OS does not react at all to any user actions. Accordingly, the previous two methods will not be able to help you with this problem. The only option left is to force the laptop.
To do this, you need to press the power button and hold it for a couple of seconds. After which the laptop will turn off and all open programs will be forcibly closed. After turning it on, you need to choose in which mode you want to start the OS, in safe or normal.
Standard system restart
This option is relevant only if the operating system responds to your actions, but at the same time slows down. Follow these steps:
- Click “Start” on the left of the Control Panel.
- In the window that opens, find the item “Finish work” and click on the arrow next to it.
- Click on the line “Restart”.
Now wait for all processes to finish and the OS to restart.
If the laptop is not using up the battery
This option is suitable for those devices that work using only a charger. If you are unable to restart your laptop, you will need to turn it off. This shutdown method is very effective, but not at all safe. You will have to pull out the charger cord, after which the operating system will be forced to shutdown.
Using this method very often, you can harm your laptop and OS, but sometimes it is necessary to use this option, since other methods may not be effective.
This article has described the easiest and safest ways to reboot the operating system on laptops. Now, with any difficulty with the operation of your device, you will have a choice of how to act in a given situation.
Windows 10 black screen due to printer drivers
During my practice, I saw black screens on RDS farms many times, and one of the reasons was the presence of old, conflicting drivers from printers. In total, I had to go into Windows safe mode and clean these registry branches. The first branch, in which you need to delete everything except the following values:
- USB monitor
- Standard TCP / IP port
- PJL Language Monitor
- Local port
- BJ Language Monitor
- Appletalk Printing Devices
In the print providers branch, remove everything except the default print providers
You also need to clean the printing processes
After cleaning the registry, I would advise you to clean your computer from garbage using Ccleaner, then you need to restart your computer in normal mode and check for a black screen.
Updating the BIOS in your computer
Recently I saw a case that a user updated his Windows in October 1809 to version 1903 and received a black screen at the entrance, in total it turned out that his hardware did NOT accept the new version of the system. The way out of it was to update the hardware BIOS through Windows safe mode. Or the opposite situation, when an advanced user, on the contrary, installed a fresh version of the BIOS and it turned out to be still unfinished, I saw an example from my friend, when he rolled onto his Asus through the ez update utility, the fresh version, after rebooting I admired the black screen, all the manipulations above had no effect, rolling back the BIOS version to the previous one brought everything back to work.
Black screen in Windows 10, solved in a minute. Consequences of the virus
The presence of a black screen may indirectly indicate that you have malware running on your system, which could easily damage the Windows registry and, for example, change the value in the HKEY_KEY LOCAL_MACHINE registry key. SOFTWARE. Microsoft. Windows NT. Currentversion. Winlogon. Find the Shell key here and check that it has the value explorer.Exe, if it is not, then you need to treat the system in safe mode, for this you can download the free dr web cureit and go through it. You can also use AdwCleaner.
Disconnecting unnecessary devices
Peripherals connected to your computer may cause a black screen or black screen with rotating dots to appear during startup. If you encounter something similar, disconnect all peripherals (such as printers, cameras, removable drives, Bluetooth, and other USB devices) from your computer.
Start your computer again, and if everything works fine, then you have a problem with one of your peripherals. You can figure out which one is causing the problem by connecting one peripheral to the device at a time, until you stumble upon the one that is causing the conflict. Once you know the device that is causing the problem, unplug it, restart your computer, and then search the web to see if there is a hotfix, or contact the device manufacturer for help.
How to fix random black screens
And then there are black screens that happen out of the blue. Windows 10’s new servicing model (that is, Endless Fixes and Updates) means Windows updates, fixes, security fixes, and driver updates are often downloaded in the background and installed at night, completely unnoticed by you. If you want to determine which Windows updates are installed and when, you can, but if they already passed you by and gave you a black screen, try booting into Safe Mode. Then they should be removed. To open the control panel and go to “Programs and Features”, then find the item “View installed updates”
After that, we look at the latest updates and remove them.Do not forget to then restart your computer and check the result.
A corrupted user profile can sometimes cause a black screen. Trying to boot into Safe Mode, creating a new user account, and then trying to log in to it may help. In the task manager, call a new task or if safe mode allows you to open Start or display a window “Execute”, after pressing WIN R keys, then type netplwiz.
You will see a window “user accounts”, press the button “Add to”
We choose “Sign in without a Microsoft account” and further.
Create a local account.
We fill in the details of the new account.
Done. New account has been created. It remains to give her administrative rights.
Select a new user, go to his properties and assign a group to him “Administrator”
In total, it turned out like this, now you can try to log in as a new user. The data can then be easily restored by copying it from the old profile.
RunOnce processes could also be the culprit. If you all see a black screen after logging in, press Control Shift Esc on your keyboard to launch the Task Manager. Click the Processes and Services tab and then find all instances of RunOnce32.Exe or RunOnce.Exe. If you find that they are running, stop the process, cancel the application, or end the service. It is better to set the service to start manually at startup.
Update from 07/06/2017
Update KB4034450 has been released, designed to fix all problems with dozens of black screens, if possible, install it as soon as possible in safe mode by slipping it through a USB flash drive or disk.
Rollback to a previous version
If you installed a major release update, for example, you switched from Windows October 1809 to Windows Media 10 1903, where you got a black screen, then you can use a bootable USB flash drive to roll back to the previous version, I have already talked about this in detail. When you restore the normal operation of the computer, you can wait a month, maybe Microsoft will fix this behavior with a fresh update.
Restart Windows 10
One of the working ways to fix the problem with a black screen after re-enabling Windows 10, which seems to be quite workable for owners of AMD (ATI) Radeon graphics cards, is to completely restart the computer and then disable Fast Startup of Windows 10.
In order to do this blindly, after booting the computer with a black screen, press the Backspace key several times (left arrow to delete a character). this will remove the lock screen saver and delete any characters from the password input field if you accidentally entered them there.
After that, switch the keyboard layout (if required, by default in Windows 10 it is usually Russian, it is almost guaranteed to be switched with the Windows Spacebar keys) and enter your account password. Press Enter and wait for the system to boot.
The next step is to restart your computer. To do this, press the WindowsR boot key on the keyboard for 5-10 seconds, enter (again, you may need to switch the keyboard layout if you have Russian by default):
And press Enter. After a few seconds, press Enter again and wait about a minute, the computer will have to Reboot. it is quite possible that this time you will see an image on the screen.
The second way to reboot Windows 10 with a black screen is to press the Backspace key several times after turning on the computer (or you can use a space or any character), then press the Tab key five times (this will take us to the on / off icon on the lock screen), press Enter, then. the “Up” key and again Enter. After that the computer will restart.
If none of THESE options allow you to restart your computer, you can try (potentially dangerous) forcing your computer to shut down by holding down the power button for a long time. And then turn it back on.
If, as a result of all the proposed, the image appeared on the screen, then it is precisely in the operation of the video card drivers after a quick start (which is used by default in Windows 10) and to avoid a repetition of the error.
What to do if a black screen occurs when you turn on your laptop
If the laptop is not communicating with you, there can be many reasons for this. When you turn on the laptop. a black screen, first of all, pay attention to its hardware. For example, the power button does NOT close the electrical circuit, one or more microcontrollers on the motherboard are out of order, capacitors are swollen, the unit or portable power source is faulty. battery.
It should be noted that these problems do not always require specialist intervention. When the laptop boots up, a black screen may indicate a breakdown of both hardware and software. Be that as it may, you should clearly know what could go wrong.
How to recognize a problem and fix it in a timely manner
When a black screen is seen when the laptop starts up and there are no character lines, the unit may not be powering its components. In this case, you need to put the battery on charge for an hour and a half.
In more serious situations, the battery may fail and NOT function at all. If this happens, you need to carefully disconnect it by removing the plastic latches, then connect the power directly. When removing the battery, disconnect the power to the laptop first to avoid possible electric shock.
The opposite situation may also arise: the battery is working stably, and the power supply is out of order. To determine this, put the battery on charge. If the mains voltage is functioning normally, but the charge indicator is “silent”, you need to perform a light test.
To do this, remove the power supply from the laptop, and, without disconnecting the plug from the outlet, prohibit the block connector and the base of a small 3-5 watt bulb. Perform this action with rubber gloves on your hands. If there is no light on, check the cord. Perhaps, somewhere along its length, the damage is insulation, and the inner core of the wire is broken. This cord must be replaced immediately. Modern power adapters allow you to replace the cable by simply removing the previous one from the corresponding connector.
However, if no obvious damage to the wire is found (there is a suspicion of a malfunction of the unit itself), you should contact a service workshop. Diagnostics and possibly repair of the internal parts of the adapter should be carried out by qualified specialists in this field.
Black screen when turning on laptop. The power button may NOT be powering
To check the serviceability of the button itself, you should dismantle the upper panel part. This generally does not require a complete disassembly of the laptop.
Next, you need to check that the button normally supplies power and closes the working contacts. Such work should be carried out either with knowledge of electrical engineering and skills in working with a soldering iron, or under the supervision of a repairman for electronic systems.
If, when the laptop is turned on, the screen is black and the buttons do not connect the necessary contacts, it must be evaporated and a similar battery inserted. At the end of the work, do not forget to screw the disassembled panel into place.
Another common reason that when the laptop is turned on a black screen and nothing is displayed is a malfunction of the screen itself or the motherboard. And if checking the monitor requires the knowledge of a specialist, then some removable elements of the motherboard can be sequentially disconnected. Then check the performance of the laptop without this or that element.
The restrictions apply only to the central processor, which is the main hardware-connecting link. The maximum that can be determined is the absence of the necessary thermal grease or the cleavage of the central core (crystal). The heat dissipating cooler may also be faulty if the cooling is NOT water.
Use Safe Mode to boot your laptop
I went to reboot the laptop, everything is fine with the Windows icon, but the black screen, I wanted to reinstall Windu, I chose it from the flash drive. All ok, but again a black screen. I pulled out the battery, tried to return Windu to its normal state, knocked out an error. What to do if your laptop screen won’t turn on?
Symptom: When you turn on the laptop, you see the Windows logo, but as soon as the boot is completed, a black screen with a cursor appears. The desktop is NOT displayed, while you can go to the task manager.
What to do. A small but effective method if you cannot restore the boot of the operating system on a laptop. Use Windows Safe Mode.
You can activate it after initializing the BIOS, to boot the operating system. After turning on the computer, hold down the F8 key on the keyboard. Among the additional boot options, you can choose the Safe Mode itself or its variants.
Remove the laptop cover and check the fastening of the RAM modules
We advise you to check the tightness of the connection of the RAM modules with the slots of the laptop: if the RAM bar has moved away from the motherboard, it is quite possible that the computer will not turn on.
Contact the service center
All of the above actions make sense to perform only if you have special skills in laptop maintenance. Otherwise, contact reliable specialists.
Check if the hard drive is detected in laptop BIOS
If the laptop does not boot and you still see a black screen, try going into the BIOS (if it boots) and check if the hard (SSD) drive is detected.
Remove conflicting drivers on the laptop and replace with working ones
What to do. Boot Windows in Safe Mode and uninstall conflicting drivers. Go to the developer’s website and download the latest drivers for your operating system version. Instructions on how to do it.
It also makes sense to contact the developers with this problem or look for a solution to your problem on the video card developers forum. Judging by the description of your problem, the black screen on the laptop is caused precisely by the driver conflict.
Clean your laptop from dust
Finally, one more tip: If your laptop is noisy when booting up, dust it off. Sometimes computer overheating directly affects the success of Windows boot.
Laptop matrix not working
Your monitor may not work. That is, the laptop matrix is out of order. It can be replaced by specialists in a service center or in a repair shop in your city.
Black screen when turning on laptop. What to do?
If your laptop does not turn on and you see a black screen after boot, this does not lead to run to the service center. In this article. Tips on what to do if this black screen appears when you start your laptop. We hope that after reading you will find the correct solution to this problem.
Reinstall the operating system on the laptop
Symptom: example of a situation:
What to do. That is, the computer turns on and successfully comes to loading the operating system. Most likely no hardware problems are observed.
If a black screen appears on a laptop when Windows starts, we recommend reinstalling the operating system. this is the best way to restore the boot.
To do this, just use a Windows 10 boot disk or USB flash drive. The best utility for writing a USB flash drive, in our opinion. Rufus.
System bootloader failure
A black screen and a cursor on it after loading a laptop or computer may indicate a malfunction in the operating system loader or one of the drivers. If the system startup options menu appears, try booting into Safe Mode. And if not, then there is only one way out. booting from a CD or flash drive. How to make a bootable flash drive is described in our article.
Checking the Monitor Power Supply
- If you have a desktop computer, check the power supply to the display first. Some users get so used to working on a laptop that, when they switch to a desktop, they don’t notice the obvious. The power button on the monitor is just off. It was not by chance that the instruction of IBM specialists, developed for the first PCs, suggested checking the power supply.
- The second common prerequisite for suddenly getting a black screen when turning on is insufficient power cable contact. In practice, there were often cases when the cable plug was loosely held in the socket, and turned off when the display was moved or the active participation of household members, including furry ones. In the office, a prerequisite for poor contact between the cable and the monitor is often the cleaning women touching the wires during cleaning.
Black screen when turning on your computer? What to do?
Black screen when loading Windows is a problem that sooner or later many users face, but not everyone knows how to fix it. What should be done? First you need to study the Possible Causes. There are many of them and they are different. They can be both technical and software, and sometimes the problem lies in the usual carelessness.
Problem with wires and / or connectors
Typical situation. problems with cables, connectors and power buttons.
Incorrect refresh rate or too high resolution
The second common problem with a black screen when loading Windows may be the incorrectly set refresh rate on the video card. The fact is that old CRT monitors operate at a high screen refresh rate, up to 100 Hz and higher. And modern LCDs can only support 50-60 Hz. This is due to the design feature of such monitors.
If you got a black screen exactly when switching from an old monitor to a new one, then you need to do the following.
- Connect the computer again to the old monitor.
- Set the refresh rate to 60 Hz and the minimum screen resolution. This can be done in the properties of the screen or a special utility of the video card driver.
- Connect your desktop to a new monitor and adjust the screen frequency and resolution for the new display.
For the same reasons, you can get a black screen on a laptop connected to an external monitor. Try adjusting the frequency and resolution for the external display as shown in the picture above.
What if the black screen when the computer is turned on is defeated by the means described in this article, but it did not work out. Perhaps the reason lies in a malfunction of parts of your PC.
The video card is out of order
With such a malfunction, the laptop or PC fan works, but it does not start and we see a black screen on the screen. According to the POST standard, we should hear one long and two or three short beeps from the speaker (built-in speaker). The specified sound indication is typical for AWARD BIOS installed in many mainstream laptops and computers.
Just be sure to make sure that the speaker is present and connected to the board. In some modern computers, manufacturers do without it, replacing them with LEDs on the motherboard and even small digital indicators. But the latter can only be found in expensive motherboards for overclockers.
A laptop almost always has an output for connecting an external monitor. Therefore, if, when you turn on the laptop, you hear the sound of the coolers, but the screen is black, then it is likely that someone switched it to work with an external monitor. Locate the external monitor function keys on the keyboard and try turning on the internal display. This is how they look on an ASUS laptop:
The F7 key turns off / on the internal screen, and F8 controls the combination of output to the external / internal laptop monitor. They should be pressed together with a function key, usually denoted Fn.
This is how the choice of modes of operation with an external monitor looks in Windows 8 and 10.
Different modes are switched by sequential pressing of the Fn and F8 key combination for the ASUS laptop keyboard shown above. So you can accidentally turn off the laptop’s internal monitor and get a black screen when turned on.
Checking the contact between the video card and the monitor
The second prerequisite for a situation when coolers work, but the computer does not turn on and shows a black screen. there is a problem with the cable between the video card and the display. There are two options here:
- The cable came out of the socket.
- The cable is not connected to the main output of the video card.
With the first case, everything is clear. Just check the integrity of the cable itself and the reliability of its attachment to the connector. But with the second case it is worth explaining. Examine the back of your computer.
If there are two connectors for connecting a monitor cable, then we are dealing with one of the following situations:
- Installed video card with two outputs.
- There is an external video card (2) and an integrated internal (1).
In both cases, there are two options for connecting the cable. I turn off the computer, switch the wire to another connector and turn on the computer again.
Perhaps someone just switched the cable to a different socket by mistake. The modern HDMI connector is NOT equipped with screws, like the old VGA, and it can be accidentally pulled out of the socket, and then plugged into the wrong socket or not fully inserted.
Black screen after restarting computer? Perhaps you have a technical problem (more details below).
Black screen after logging into Windows computer (there is a connected screen)
The first scenario in which the speech will go is a black screen, which occurs after logging in.
Force Start Explorer
- The first thing to do is press Ctrl Alt Del, this should bring up the Task Manager. If it happens, great!
- Click File. Run New Task.
- Enter explorer.Exe and hit Enter.
Perhaps this will solve the problem.
Disconnecting external devices
To solve the problem, Disconnect all external devices and restart your computer. This primarily applies to devices such as a second monitor, projector or TV. If the computer or laptop displays the boot process, then one of the external devices is causing the problem. If the error disappears, then connect the external devices one by one until you get a black screen again. After that, remove the last device you connected and make sure the monitor is working again.
DO NOT Use the Problem Device Until You Get an Answer to the Current Problem from the Manufacturer.
Black screen when booting Windows 10, 8, 7 on a computer or laptop. What to do?
Read how to fix the black screen problem in Windows 10. Possible causes and solutions If you encounter a black screen problem in Windows 10, 8 or 7, then there are 2 different scenarios that will help you determine the cause of the error and fix the problem.
In the first case, you can log into your computer, but you do not receive any image on the screen after logging into the system. In the second case, you cannot even log into the computer. This article will tell you how to fix the black screen error after logging into Windows, booting the system. We will consider options both with the introduction of the mouse cursor, and without it.
Switching to Safe Mode
If removing external devices does not resolve the issue, go to Safe Mode.
- Reboot your computer.
- On the lock screen, tap on the power icon towards the bottom left of the screen.
- Hold SHIFT and click on Restart.
- After rebooting, you will get additional boot options. select Safe Mode with Command Prompt.
Perhaps instead of rebooting, you will be presented with a screen with 3 options to continue:

- Right click on the monitor, select Uninstall.
- Reboot to reinstall the driver.
Black screen when turning on the computer (without login option)
If a black screen appears in the login windows, you will NOT be able to boot into Safe Mode using the above method. To log in, you need a bootable DVD or a USB flash drive with the Windows distribution. You can also create a Recovery Disc on another work Windows 10 computer.
- Connect bootable media to your computer;
- Set the boot priority from the desired media in the BIOS;
- Download computer.
After downloading, you can try to boot in safe mode and carry out all the same actions that we considered in the previous paragraph. To select Troubleshoot, then Advanced Options, then Boot Options and then restart in Safe Mode with Command Prompt.
If the problem persists, you can try resetting Windows to its original state and performing a clean installation of the system.
Laptop users experiencing black screen issue have been helped by a way to reset BIOS to default. If the computer shows signs of life (coolers are working), connect it to the monitor or do the blind procedure:
- Turn on the device.
- After turning on, press the F10 key for 10 seconds (enter BIOS).
- The boot menu will open and press F9.
- Press Enter (rollback to original settings).
- Press F10 (exit BIOS) /
- Press Enter to save changes, exit and restart your computer.
Reasons for malfunction
The reasons due to which the laptop screen does not work can be divided into several groups:
- Damage to the south or north bridge of the motherboard due to mechanical interference or overheating of the device.
- Malfunctions with the central processor or video card.
- Broken loop, laptop matrix or backlight.
- RAM crashed or fell out of the socket.
- Malfunctions in the hardware settings of the computer.
- The battery stopped working.
In the first three cases, repair or replacement of parts is required. Malfunctions described in the remaining paragraphs can be tried to be eliminated by yourself.
If the laptop shows signs of life when turned on:
- Connect it to a 220V network, check if there is voltage (look at the laptop charge indication).
- There is an indication, but the laptop does not turn on. disconnect the charger from the laptop.
- Pull out the battery as shown in the picture.
- Clean clogged contacts.
- Press and hold the power button for 20 seconds to remove the residual charge from the motherboard and laptop components.
- Connect the charger and turn on the device, check the screen operation. If it works, replace the battery and check it again. Laptop won’t turn on? We recommend replacing the battery.
- Connect monitor via VGA or HDMI outputs.
- Start your laptop and follow the process.
- If the BIOS and Windows boot was successful, there is a problem with the screen or its connection (perhaps a loop has come off).
Elimination. What to do if laptop won’t turn on. black screen?
Every third laptop owner is faced with a black screen at startup. There can be a lot of reasons that cause the problem, but before contacting a computer repair service, we recommend that you diagnose yourself. We will talk about this below.
Checking RAM sticks
There is a possibility that the motherboard has stopped recognizing random access memory (RAM):
- Unplug the laptop and take out the charger, turn it over, unscrew the screws.
- Open the back cover.
- Gently push the latches in different directions to remove the RAM.
- Take out the OP strips and clean the contacts with an eraser.
- Change the connector (if there are several) or places of the OP.
- Insert the OP backwards at a 45% angle and press lightly from above. The clamps will do all the work themselves.
- Check the connection of other devices (hard drive or SSD bracket).
- Close the cover, plug in the device and check its operation.
If the advice of the article did not help you, we recommend that you contact the service center. Most likely the malfunction is in the hardware. Also write to us, maybe together we can find the problem.
