Why does my laptop screen go black when it lights up

If you look closely, you can see that the image is not backlight, and many pseudo-black screens with aging lamps sometimes re-turn on and off the lamps, for example, the screen can be re-lit for a while, and the pseudo-black screen needs to be replaced. If it's a really black screen, it is mostly a problem with the graphics card chip in addition to problems such as standby hibernation.

Expansion: Each hardware has its own default or specific working environment, and it cannot be set beyond its working permissions, otherwise it will crash because the hardware does not meet this requirement.

At present, some small brands of computer hardware products are often put on the market without passing the inspection procedures, among them, there are many hardware products that are not up to the standard in the shroud of good quality computer hardware is very hidden, and it is not easy for ordinary people to see.

Test after updating the graphics card driver, and if the fault persists, replace the graphics card directly.

Check whether the memory module is in good contact with the motherboard, whether the quality of the memory module is excellent, and plug the memory module again, or replace it with a new one. If there is a problem with the memory module, the computer will have four consecutive "tick" sounds when it starts. If the memory is oxidized, use an eraser to use a gold finger.

Then there's the problem with the graphics card.

Reasons and solutions for the black screen when the laptop lights up:

1. Turn on the power and press the power button, and there is no movement on the computer.

Analysis: At this time, the power supply should supply power to the motherboard and each hardware, and there is no movement to indicate that there is a problem with the power supply part.

Here's how to check it:

1. If there is a problem with the mains power supply, please check whether the power socket is normal and whether the power cord is normal.

2. If there is a power supply problem, please check whether the connection between the motherboard and the power supply is loose.

3. Motherboard problems, if there are no problems with the above two, then the possibility of motherboard failure is relatively large. First of all, check whether the connection between the motherboard and the boot button is loose and whether the switch is normal. If not, you can only try replacing a laptop motherboard.

There are generally several reasons for the black screen: (1) the display is powered off, or the display data cable is not in good contact. In addition, the computer has been used for a long time, and the power cord of the monitor is easy to oxidize and break;

2) The motherboard CMOS battery is dead;

3) Poor contact or damage to the graphics card;

4) Poor or damaged CPU contact;

5) Poor contact or damage of memory modules;

6) The machine is infected with CIH virus, and the BIOS is refreshed destructively;

7) Check the plugging and unplugging, if necessary, you can use a rubber to remove the oxide film on the gold finger;

8) If the floppy drive has a floppy disk, many times it will cause the computer to start or restart, and the computer will have a black screen and cannot enter the system. To avoid such situations, it is also possible to cancel the floppy disk boot item in the BIOS.

You link the host to someone else's monitor, you can test if it's a problem with your monitor, and if so, it can be solved in this way.

You start with a different monitor and set your refresh rate to the lowest and then try to increase it! Screen Right Arrow -- Properties -- Advanced -- Monitor -- Refresh Rate Remember, turn up from the lowest.

There is a problem with the monitor driver. Try another one. If you're using win7, there's no way. There is only a reload system.

You got the wrong wire, connect the power cord of the router to the monitor

Hello dear, happy to answer your <>

The situation that the screen of the laptop goes black immediately after turning on the screen may be due to hardware failure or software problems. Here are some of the workarounds you can try:1

Restart your laptop: Try a simple reboot of your computer first. Press and hold the power button, wait for your computer to shut down, and then restart it.

Your computer might fix some issues automatically. 2.Check the power adapter:

Use the correct charger to check whether the power cord and plug of the power adapter are connected securely, and check whether there is a fault such as a short circuit in a hail silver connection. 3.Check the LCD screen connection cable:

Open the case on the back of your laptop and check if the LCD screen connection cable is loose or damaged. 4.Enter Safe Mode:

Press the F8 (Windows 7 8) or Shift+F8 (Windows 10) keys when the computer is booted up and select Safe Mode. If the laptop boots normally in this case, it's possible that some driver or application is causing the problem. 5.

Use a repair tool: If you are able to enter safe mode, you can try to use the repair tool that comes with the system (such as Windows Boot Repair, Recovery Console, etc.), or you can use a third-party repair tool. 6.

Reinstall your system: If the above measures don't solve the problem, you can try reinstalling your system to fix possible software issues. Take care to back up your important data so that you don't lose it.

If none of the above measures solve the problem, then it is likely to be a hardware failure. At this time, it is recommended to find a professional computer repair technician for inspection and repair.
