The laptop turns on but the screen is black what to do

How to boot a laptop into Safe Mode?

Quite often, the laptop reboots after turning it on and the PC screen simply does not have time to boot normally. At the same time, it is advisable to load it in safe mode:

  • Before loading the device, you need to enter another boot method. the F8 button (sometimes the DEL button or other buttons of the F row are suitable for different models). It is best to look at the instructions for the motherboard;
  • In safe mode, you need to choose one of 3 boot options;
  • Then, we enter the OS in this mode;
  • Also, you can enter the system in BR in other ways. For example, through the command line “cmd” and “msconfig”. These applications are launched if you enter these labels through the “Start” search.

How to remove possible faults in the operating board?

I have already written in my articles, and I will repeat today that the computer needs to be cleaned from dust. But, if such cleaning was carried out incorrectly, then it is quite possible that your laptop will turn on, but the screen will not function.

Also, this action can occur if you installed the RAM card incorrectly. Failures are possible both with RAM and with the functioning of other loops. In any case, you will need to disassemble the laptop and find out how exactly you connected everything.

An error in the operation of the operating board could occur if you accidentally spilled water on your keyboard or simply increased humidity in your room. To solve this problem with RAM boards, we will perform the following operations:

  • You need to turn off the charging and battery;
  • Remove the laptop cover where the operating board is located;
  • If your microcomputer does not have such a compartment, it is advisable to disassemble the device completely;
  • Next, you need to bend the board mount carefully;
  • We take out the operating board itself, if there are several of them, we take out everything;
  • We blow all elements with compressed air. The main thing is that it is dry and clean;
  • Have you noticed signs of oxidation on the elements of the board? Don’t forget to clean them;
  • Next, all the strips need to be installed back into the PC and secured with special clamps until you hear clicks.

After completing these operations, we collect all the elements back. Do not forget to screw the unwound parts back. If the operation of removing the planks could not help you, it is quite possible that other parts will fail. Quite often the loops break, perhaps a slight short circuit or the backlights simply break. in this case, you need to contact the master.

Black screen with cursor

When the PC overheats, some of its devices are turned off. For example, the same monitor. It can turn off in full screen, or some part of it. Due to overheating, the video card turns off more often than others. If so, you need to turn off the device and cool it.

Usually, the temperature is checked using either AIDA64 or Speccy. It is advisable to check the temperature twice a week, or at least once.

These programs show the temperature of other parts of the mobile gadget. When the device overheats, the display may also turn off:

  • The CPU also has the ability to turn off the monitor when it overheats;
  • When the motherboard overheats, various problems are possible in the PC;
  • When the hard disk drive overheats, there are also problems with programs and utilities on the PC;

When errors occur in settings or a failure in the functioning of the computer, the only method of restoring programs to a failure is to boot the computer in safe mode (BR).

How to remove an error in BR?

Even after loading the computer into the BR, your laptop still loads automatically? In this case, you need to do the “Windows Restore”. To do this, Windows needs to select a version of the system, to which it is easy to return: make the choice of the date at which the screen worked perfectly.

In the event that you managed to launch the OS and the screen started working, then it is advisable to start updating the video card drivers and BIOS. Including with a perfectly working monitor, it is advisable to update the drivers periodically, about once every 30 days. It will be easier for you if your PC updates them automatically.

Top Factors That Cause Black Screen

There are dozens of factors due to which such a screen appears. From here, to make it more convenient, we will divide them into categories:

  • The hardware of the computer is incorrectly configured;
  • There is a malfunction in the battery or charging;
  • The monitor cable is cut off, the backlight or matrix is ​​out of order;
  • The computer’s RAM or the slot of this board is out of order;
  • The video card is out of order;
  • The system board is damaged due to overheating or damage.

Of course, not all of these malfunctions are eliminated by the user himself. For some problems, only the master is competent. Therefore, let’s take a look at which of these tasks a person can fix on their own. One of the most common problems is video card failure. To find out if the screen is working, the fastest way is to connect a second external screen. Does it also not function for you? In this case, the fault lies with the video card.

It is impossible to change various parts in a laptop yourself without having the necessary knowledge. In this case, you need to contact a professional. Of course, you can start repairing your laptop yourself. But, the matter can go so far that you cause more damage to the computer than it was before your repair. The only way out in this case is to buy a new monitor.

The monitor stopped starting due to viruses

Your screen still won’t launch? Then it is possible that your computer is infected with pests. In this case, you need to scan with the antivirus installed on your computer. If not, then we use the one-time Dr.Web cureit. Didn’t you find any pests? In this case, you need to repair Windows or reinstall it.

Let’s analyze the functioning of the monitor

You have a reason to think that the monitor is not working due to mechanical problems, in this case you need to find out how the video card works with the motherboard.

So, let’s connect a second display to the laptop using the HDMI input (VGA is possible). We turn on the computer. If after switching on the second first screen is working, then the monitor or backlight loop on the monitor is faulty.

Important: you can start starting your computer when you have already connected an external screen. To freely switch from monitor to monitor, you need to use the Fn and F8 buttons. Relevant for ASUS and other brands.

Further, we will carry out all operations to remove failures and errors in the settings and various programs with a faulty display using a second monitor (you need to take it from friends for a while) by connecting the monitor via the VGA / HDMI input.

The laptop screen does not turn on the screen is black but the laptop is working

Good afternoon friends. The laptop screen does not turn on the screen is black, but the laptop is working. Everyone can face this, but what to do? Consider the reasons, because there are a lot of them. If the monitor does not light up, this does not mean that the laptop has malfunctioned. Beginners in a similar situation for the most part rush to the service center. But, the fact is that most of such troubles with a black screen can be eliminated by ourselves. So, first, the user must reset the hardware settings, and then look for the causes of this problem.

How to remove an error in BR?

Even after loading the computer into the BR, your laptop still loads automatically? In this case, you need to do the “Windows Restore”. To do this, Windows needs to select a version of the system, to which it is easy to return: make the choice of the date at which the screen worked perfectly.

Including with a perfectly working monitor, it is advisable to update the drivers periodically, about once every 30 days. It will be easier for you if your PC updates them automatically.

You need to install a working BIOS version

If your second screen works fine, but your computer screen refuses to work, also disabling the settings and returning to the factory settings BIOS could not help, in this case it is advisable to reflash the BIOS.

It is possible to update the BIOS in different ways:

  • Using the “MS-DOS” option;
  • Using the OS;
  • Without entering DOS and starting the computer.

The easiest way to update the BIOS is to use third-party software. But, it is more correct to manually go to the main resource of the creators of your motherboard and simply download updates from this site.

The main thing is to create a backup copy of the OS or at least a restore point before installing the BIOS. When you start installing BIOS without an access point, your system may crash and you will lose all settings.

Getting started troubleshooting

  • Turn off the minicomputer and pull out the cord from the socket;
  • Then, take out the battery from the device;
  • Press the power button for 25 seconds;
  • Next, you need to insert the battery back into the computer;
  • We connect the charging;
  • Then, turn the laptop back on.

After you reset your hardware settings, if your PC starts to boot, it will ask you what type of OS to boot. Choose “Normal Windows Startup”.

Also, this screen may appear due to problems with the BIOS. The BIOS is also easy to reset. So, you updated its drivers and reset the settings, but they did not help you. In this case, you need to disassemble the laptop.

How to boot a laptop into Safe Mode?

Quite often, the laptop reboots after turning it on and the PC screen simply does not have time to boot normally. At the same time, it is advisable to load it in safe mode:

  • Before loading the device, you need to enter another boot method. the F8 button (sometimes the DEL button or other buttons of the F row are suitable for different models). It is best to look at the instructions for the motherboard;

  • Then, we enter the OS in this mode;
  • Also, you can enter the system in BR in other ways. For example, through the command line “cmd” and “msconfig”. These applications are launched if you enter these labels through the “Start” search.

Software problems

Recently installed software may be causing your graphics card drivers to malfunction. In this scenario, when the laptop boots up, a black screen is displayed with no clear signs of a normal login in the form of a prompt sound.

To remove recently installed programs, you need to boot into Safe Mode. For this:

Laptop Screen went Black but still running Fix

  • at the end of the BIOS loading, the F8 button is pressed;
  • if the laptop does not display diagnostic messages, you can quickly press and release the button constantly immediately after turning on;
  • when text lines with boot options appear on the screen, select safe mode.

After turning on the laptop in safe mode, you should uninstall recently installed programs. After reboot, the system will be restored.

Broken loop or failure of the backlight system

What to do if when the laptop boots up a black screen, the fan works but nothing happens? The answer is simple: check the operation of the external output of the video card. To do this, an external monitor must be connected to the laptop. This can be done using the connector on the side panel.

laptop, turns, screen, black

If your laptop has a modern HDMI connector, you can connect it to your TV to test it. If the indicators are on, the coolers are noisy, and the image has not appeared on the main screen and the external monitor. you should try pressing the F6 button to forcibly switch to the connected image device.

RAM check

The reason why the laptop won’t boot and the fan is running might be due to a RAM failure. For instance:

  • one of the planks came off due to the shaking of the device;
  • due to periodic switching on after arrival from frost, condensate and oxides formed inside the RAM connectors;
  • contact group of one of the memory lines is oxidized.

To check the status of the RAM, you will have to dismantle the protective cover on the bottom of the laptop.

Important! This should be done only if the warranty period for the product has expired. One of the screws holding the cover is sealed. It rips off when you try to unscrew, which automatically means the warranty is canceled.

Before use, the laptop must be unplugged and the battery removed. After removing the cover (it can pry along the edges and go up or move towards the edge of the case), access to the RAM strips is opened. To remove them, you need to swivel the side latches. After that, the bar rises 45 degrees and is pulled out.

It is required to check the cleanliness of the connector, as well as the condition of the contact pads on the memory line. If there are traces of oxides, dirt, they are removed with alcohol, followed by a thorough rubbing with a regular school eraser for erasing a pencil. The strip, in which the contact foil is wiped through, must be replaced.

Installing the ruler is done upside-down. The strap is tightly inserted into the connector (its protrusion and the notch on the line of the memory contact group must match) at an angle of 45 degrees until it stops. After that, the RAM line is lowered slightly. It is necessary to make sure that the latches are in their regular places, in the recesses on the side panels of the plank.

As a conclusion

Many information sources recommend resetting the BIOS of a laptop if it does not turn on or there is no image on the screen. This step does not seem rational. The fact is that before installing the modern operating system Windows 10, Windows 7, the service engineer could switch the operating mode of the disk controller to ACHI. When you reset the BIOS, the IDE value will be returned. In this case, the system will not be able to boot under any circumstances.

If you decide to overwrite the BIOS, you should refer to the instructions for the laptop. It contains all the data necessary to carry out this operation. Many laptops, including the already mentioned Lenovo brand, require pressing a special key or a combination of these to enter the BIOS. All the necessary information is set out in the operating instructions for a specific model.

Battery breakdown

If the laptop does not start, not a single indicator is on, or the fans are noisy, it is worth checking the battery status. For this, it is disconnected. The laptop is connected to a 220V network with a charger. If the system unit works in this mode, it means that an internal breakdown of the battery has occurred. It is enough to replace it to resume normal operation.

Difficult problems

The absence of an image on the display with obvious signs of system operation may mean a failure of the video chip or central processor. Especially often this problem appears on Lenovo laptops.

Built on single-chip solutions, they can come out of standing due to severe overheating or static discharge to the external port. Unfortunately, such a problem is diagnosed only in a service center. Getting rid of her will cost money. In the case of Lenovo. very impressive.

Driver problem

The case when the laptop is working, but nothing is displayed on the screen, may be due to an outdated version of the BIOS of the motherboard. In this case, the following happens:

  • the next generation operating system, such as Windows 10, automatically installed new drivers for the video card;
  • the power management scheme provided in the new software cannot work correctly with the resources of the motherboard;
  • when the laptop is turned on, the monitor does not turn on, but the power button is on, there is a sound of cooling, logging in. this shows that everything is working fine.

In this situation, the user sees only a black screen with a cursor. In Asus, Acer laptops of old revisions, for the appearance of an image, it is enough to close and reopen the lid.

RAM is defective

Alternatively, you should check if the RAM strips are well inserted. They can also cause black screens.

Problem with wires and / or connectors

Typical situation. problems with cables, connectors and power buttons.

Laptop display check

If after resetting the hardware settings there is still no image on the screen, then try to determine which component has failed the card, matrix or other part of the display. An external monitor will help you do this. For example, on the ASUS website in the support section, it is recommended to do the following:

  • Connect an external monitor to the laptop using the available interface. HDMI or VGA.
  • Turn on your laptop. Use the FnF8 shortcut to select to broadcast the image through the connected monitor.

If the image does not appear on the external screen, then the problem lies in the operation of the video card. This is true for laptops from Lenovo, Acer and other manufacturers as well. If the picture is displayed on the monitor, then you should continue to look for a problem with the laptop display. The check should be carried out if the laptop fan is noisy, an indicator is on, or there are other signs of the laptop turning on. If there is nothing like this, then perhaps the problem is not in the display. the entire laptop does not work.

Who will help this method?

The method I described will help you in the event of a malfunction of the hardware settings, but when the laptop falls into water, it does not work.

Everything that you do next must be done carefully and accurately, if in doubt, then immediately contact a specialized service center, where highly qualified and qualified specialists will help you and eliminate the problem of a black screen on a laptop. It is worth noting that repairing a laptop will cost you a little more than repairing a stationary PC.

However, if you nevertheless decided to take this step, then let’s go!

Friends, if your laptop does not turn on a black screen appears, then carefully repeat after me as I wrote in the article. In principle, there is nothing difficult in solving this issue, and if you have any questions for me, you can safely ask them in the comments.

Reinstalling the RAM module

Sometimes the image ceases to be displayed on the screen due to incorrect installation of the RAM. Partial disassembly of the laptop, removal of the memory module and its reverse correct installation can help.

All of the above methods are good for initial diagnostics and help in eliminating simple causes of a malfunction. Keep in mind that in order to avoid undesirable consequences, it is recommended to entrust the repair of your computer to professionals.

What to do if the laptop turns on but a black screen

Problems waking up from hibernation

If the screen stays black when you wake up from sleep, the first step is to check your graphics card drivers. The software must be the latest version and fit the system. You can download the latest drivers on the laptop manufacturer’s website.

In some cases, the problem is caused by incorrect input devices support for Windows hibernation. Waking up from sleep is carried out using a touchpad (mouse) or keyboard. If an external device is connected, then it can block the wake-up of the laptop. To fix this flaw:

laptop, turns, screen, black
  • Open Device Manager. Expand the “Mice” or “Keyboards” section, depending on which device is blocking wake-up.
  • Right click on hardware and open properties.
  • Go to the “Power Management” tab and uncheck “Allow the computer to wake up from sleep mode”.

Save the configuration by clicking “OK”. Do not prohibit waking the laptop at the same time as the mouse and keyboard, otherwise you will not be able to wake up the computer from sleep. Set the ban on both devices in turn, checking if there is a positive effect.

The video card is out of order

With such a malfunction, the fan of the laptop or PC 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 indicated sound indication is typical for AWARD BIOS installed in many mainstream laptops and computers.

POST is a BIOS self-test system. We recommend reading the article about BIOS.

Just make sure that the speaker is present and connected to the board. In some modern computers, manufacturers do without it, replacing it with LEDs on the motherboard and even small digital indicators. But the latter can only be found in expensive motherboards for overclockers.
