Screen is constantly flickering

[RoseKaur]

Hello, my laptop screen is constantly flickering. I have tried all possible solutions available on internet but its still not resolved. I contacted Microsoft and they said maybe updating to Windows 11 would resolve it but it didn't. 

I am a college student and this laptop is my necessity what can I do to fix this?

PS: Where can I find hp customer service number?

This is not good.  Possibly the laptop or the screen has a problem.

Does the flickering happen right away or after a few minutes.?

If after a few minutes perhaps no air is circulating and the CPU got too hot.

When was the last time you blew dust out of the system?

Do you feel air flow from the side?  Is the bottom hot?

Borrow a monitor or tv set and connect as an external monitor.  Does the 2nd monitor flicker?  if so, the problem is the laptop graphics.  If it works fine with a tv set or 2nd monitor the problem is the display.  Can you stop or change the flickering by adjusting (tilting) the position of the display?  if so possibly the internal cabling is defective

If the problem is just the display, a cheap solution, assuming you have a TV available, is to get an inexpensive WiFi adapter, connect it to the tv, and project the laptop to the tv.  Obviously, you cannot do that if the laptop is taken to the school.  Depending on you location, several companies offer educational discounts for laptop.

Thankyou! The issue isn't resolved but I appreciate your suggestions

If connected to an external monitor, the monitor doesn't flicker. 

I have also realized that when the screen flickers, the background app, Google search, or any work I do is still running in the background.

I have updated and reinstalled the drivers

When at bios setup, the screen doesn't flicker

 irrespective of tilt, tablet mode, or laptop mode - the screen keeps flickering
