What is the reason why my laptop suddenly goes black? What s wrong?

1. If the screen is black when running a specific program, please try to uninstall the program and reinstall it, or install it in a different version.

2. Enter the safe mode, and confirm whether there is a black screen in the safe mode? If the security mode is normal, it is usually caused by software conflicts, please check whether there are any recent system optimizations and software installation operations, and you can uninstall the recently installed updates and program software through [Control Panel] - [Programs and Functions].

4. Check whether the computer has been installed with memory or other hardware? If so, please remove the additional memory and other hardware before turning on the computer to confirm.

5. If it still doesn't work, it is recommended to back up the data and try to restore or reinstall the system.

6. If you still can't solve the problem through the above methods, please bring the machine to the service center for testing.

There are many reasons why a laptop has a black screen, the main ones being that the monitor is damaged and the motherboard is damaged. Of course, the phenomenon of black screen can often be seen, if your laptop is used for a long time, it will cause damage to the graphics card, poor contact, and parts because of the high temperature and the screen can not be displayed, or artificially destroy the computer, so the phenomenon of computer black screen will appear. This phenomenon is not terrible, and there are many ways to put your computer back to its original state.

What happens when the computer screen suddenly goes black?

Start by checking that the contact is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

If there is no problem with contact, it is best to try a different monitor to make sure that the monitor is fine. If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard. A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded.

1. Power supply problems.

If it is an external power supply, first see if the power supply is not plugged in properly or there is a problem with the plug. If you are using a battery, it may be that the laptop power supply is running low.

2. The motherboard is faulty.

Motherboard failure is the main reason why laptops won't turn on. It is often caused by factors such as liquid ingress of the notebook, breakage, and damage to the components of the motherboard itself.

3. Circuit failure.

In addition to artificial liquid ingress and short circuits, most of the failures of laptops that cannot be turned on are problems with the protection isolation circuit, the failure of the boot circuit and the EC peripheral circuit, and sometimes the circuit will be burned out in a large area.

4. BGA failure.

BGA failure is also a failure caused by the laptop not being able to turn on, which is extremely common in notebooks that use DBM as the South Bridge chip in the Swift Relaxation generation.

5. If it cannot be solved, it is recommended to send it to the after-sales center for maintenance.

Hello, can you take a look at mine.

Here's how to fix it:Reason 1: Battery, power supply problems1, check all cables (including power plugs) to ensure that all devices are properly and tightly connected together.

2. Check whether the laptop has power (although most people will not make such a low-level mistake), because the notebook has a built-in battery, so it can be used without plugging in the power supply, of course, the time is limited, when the built-in battery is used up and not charged, it will cause the notebook to fail to turn on, at this time we just need to plug in the power to charge.

Reason 2: It may be caused by a virus infection, press and hold F8 to enter the advanced options page, select "Latest Correct Configuration", and then press Enter. After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, restart after removing the driver, if it doesn't work, then rule out this reason.

Reason 3: Hardware problem: Disassemble the notebook to check whether the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to ring means that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it doesn't start at this time, it's best to send it for repair, and a professional will check whether there is a problem with your hardware one by one. Reason 4:

Display ProblemsIf the power supply** is working, but the screen is still pitch black, try connecting another monitor to your computer (you can borrow one if necessary) to make sure it's not a monitor issue.

Here's how to restore the laptop black screen to normal:

Method 1: Ctrl+Alt+Delete key combination to restart.

If you encounter a sudden black screen, you can try to use the Ctrl+Alt+Delete key combination to restart the computer, which can solve most of the black screen problems.

Method 2: F8 is correctly configured for the last time.

If it doesn't solve the problem after trying to restart, then shut down the computer first, and then keep pressing the F8 key to enter the system operation when the computer is turned on, and select the last correct configuration to try to solve the black screen. This can effectively solve the problem of black screen caused by driver conflicts or system poisoning.

How to prevent black screen in a notebook:

First, ensure the capacity of the system disk. Generally, the computer system is in the C drive, and it is best not to install things in the C drive, and to keep the C disk clean and capacy.

Secondly, if it is a desktop computer, you must keep the computer case clean, (the case dust can cause the CPU fan to not work properly, so that the CPU temperature is too high and the CPU is used too high, it is easy to cause a crash) If the computer case is closed. There will be a lot of dust inside after a while, so be careful to clean it up!

Then, you should regularly use a computer optimization tool to clean up the computer's system cache and junk files, too much computer cache and junk files will affect the speed of the computer, and it is easy to cause the computer to crash if the computer load is too large.

Hello: The following methods are for your reference:

The true black screen is mostly a problem with the graphics card chip,If it is the chip of the NVIDA graphics card door, including the integrated graphics card, if you want to completely solve it, you must change to a new and improved version of the graphics card chip,Otherwise, it must be **,If it is not the chip of the graphics card door, such as ATI, you only need to add welding。

What to do if the laptop suddenly goes black.

It is recommended that you update the motherboard driver and graphics card driver (if it is independent), if the problem has not been solved, the reason is inconvenient to say, in order to prevent losses to your machine, it is recommended to contact customer service!

There can be many reasons for this, it can be hardware or software, and it must be known through specific testing.
