If your laptop has a black screen and the power light is on, here are some suggestions to try to fix the problem:

1.Force Restart: Press and hold the power button for more than 10 seconds to force the laptop to shut down. Then press the power button again to turn on the computer. This can sometimes solve some temporary problems.

2.Check hardware connections: Make sure all hardware connections (such as power, keyboard, mouse, monitor, etc.) are properly connected. If anything is loose or damaged, it may result in a black screen.

3.Check the battery: If the laptop is running on battery power, unplug the power adapter and try running on the battery. This can help determine if the issue is related to the power adapter or power supply.

4.Check the screen connection: If there is a problem with the screen connection, it may cause a black screen. Check the screen cables and slots for loose or damaged slots.

5.Update Drivers: Sometimes, driver issues can cause a black screen. Try updating your graphics card driver or other critical drivers to resolve the issue.

6.Check the system logs: Run the Windows Error Reporting Tool to see if there are any error messages related to the first and last screens. This can help identify the root cause of the problem.

7.Factory reset: If none of the above methods can solve the problem, you can consider doing a factory reset. This will erase all user data and settings, restoring the laptop to its factory state. In some cases, this may help resolve the issue.

8.Seek professional help: If none of the above methods can solve the problem, it is recommended to seek professional technical support or take it to a nearby repair station for inspection and repair.

Before trying any solution, make sure that you have backed up all your important data in case you lose it during the recovery process.

Check that the power cord is securely clumped and try to plug it back in. The host is working normally, the power indicator of the monitor is on, but the monitor screen is black, it may be that the transmission sock cable connecting the computer monitor and the computer host is loose or broken. We hope you find this service <>helpful

When the computer is turned on, the screen is not on, check whether the monitor has been turned on. Check that the power cord is secure and try to plug it back in.

The reasons for the power light of the computer to turn on but the black screen are that the graphics card is loose or damaged, the memory slot is not in good contact, and the power supply circuit of the computer motherboard is abnormal.

1. The slag graphics card is loose or damaged.

If the independent graphics card storage of the computer graphics card is loose or soldered, the computer graphics card will not work properly, resulting in the computer power supply being smooth, but the screen will be black. In this case, the graphics card can be unplugged and plugged in; If it is found that there is a phenomenon of false welding, it needs to be sent to the maintenance office for maintenance.

2. Poor contact of memory slots.

Poor contact of the computer's running memory slot will cause the computer to have a black screen and cannot be turned on. At this time, you need to remove the slot where the memory is running, and at the position of the gold finger of the memory, that is, the area where there is a metal sheet, wipe it back and forth with an eraser, insert it back, cover the back cover, and it can generally be solved by booting.

3. The power supply circuit of the computer motherboard is abnormal.

There is an abnormality in the power supply circuit of the laptop motherboard, such as clocks, calibration, power distribution. Or the MOS tube is abnormal, and the screen is black. In this case, it is necessary to send the computer to after-sales service or repair the computer motherboard.

Tips for computer maintenance

1. Normal shutdown.

This point is the point that everyone is most likely to ignore, open a lot of background programs in the office, save trouble when shutting down, and force shutdown, which will affect the normal reading and writing of the hardware, resulting in information loss, and in serious cases, it will cause permanent damage to the hardware. It is also necessary to avoid sudden power failure, which will cause irreversible damage.

2. Maintenance of LCD screen.

It is recommended to turn on the power-saving mode on the computer LCD screen, and the computer will automatically turn off the screen when not in use, which can not only save power, but also extend the life of the LCD screen. At the same time, it is recommended to use a special detergent for daily wiping and cleaning.

3. Avoid vibration when using.

The computer should try to work on a flat table or platform in daily use, and remember to handle it gently when moving, to avoid bumping, if it is easy to bump, the most serious consequence is to damage the hard disk, so try to be equipped with a special notebook bag, because the special notebook bag has been treated with shock absorption, which can effectively protect the hardware security.

1. The black screen of the computer is a phenomenon that is relatively easy to appear, especially in some older computers or assembled computers. There are many reasons for the failure of a computer black screen, such as a damaged monitor, a damaged motherboard, a damaged graphics card, a poor contact of the graphics card, a damaged power supply, a damaged CPU, etc. For the treatment of the black screen of the computer, the method of eliminating and replacing is basically adopted, and the principle should be based on replacing and eliminating the most suspicious parts first.

For ordinary computer users, professional knowledge is insufficient, you can follow the following steps to analyze the cause of the failure, so that you can do it yourself.

2. First of all, check whether 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.

3. If there is no problem with the contact, it is best to try it with another monitor to make sure that there is no problem with the monitor.

4. If there is no problem with the display, 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 it is not normal, you can change a power supply to give it a try.

5. If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory module, 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.

6. Change a normal CPU (should be compatible with the tested computer), boot and re-test, if the black screen still appears, you can only change a motherboard, and the problem should also appear on the motherboard.

7. The black screen failure of the computer may indicate that the computer has a more serious problem, and you may wish to eliminate it according to the above methods when the black screen phenomenon 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.
