There are many reasons why the laptop screen flickered, and the screen cable parts will account for more than 90% of such failures.

1. Test the external monitor to see if the external monitor has a similar situation, so as to determine whether this fault is caused by the host part or the screen head part.

2. The external display is normal, please re-plug and unplug the screen cable interfaces on both sides and fix and check whether the cable routing at the screen axis may be squeezed and interfered with by other components.

3. The above operation is invalid, replace the LCD screen test, if the fault disappears, it is the LCD screen failure, and the fault still exists, please apply for the replacement of the screen line.

4. If there is a similar fault in the external display, you need to consider updating the graphics card driver, flash plug-in or restoring the system.

5. Software problems cannot be troubleshooting, replace the CPU test, to determine whether the fault is caused by the CPU or the motherboard.

I'll tell you responsibly, I've been in the same situation.

Open Master Lu and reinstall the driver.

The most likely cause of this problem is that your computer has shut down or slept inappropriately at some point, causing a driver problem.

If the driver reinstallation is not right, it can only be a hardware problem.

In this case, the general LCD cable (even on the screen) is loose, and if you are bolder, you can take it apart and do it yourself.

Disturbed by the magnetic field, let's demagnetize.
