Display flickers randomly

AU 620TX
Linux

Hi,

As the title describes the screen of my HP laptop just starts flickering randomly any time. Sometime it would stop after a few minutes other times it would do it continuously. To stop it I need to put my laptop to sleep.

Can you please tell me what the issue is and how to stop it?

Thank you

Hardik

Display flickers randomly

@JohnnyGat (from Saints Row? Pleasure to meet you, finally) 😉

Here's what you need to do, to identify the issue and resolve it accordingly:

  • If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
    • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
    • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

While you respond to that, I have a few more steps that should help: 

Perform a power reset (no data loss) using these steps: Click here, proceed to next step if this works

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

 

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

 

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue,
use this link for details on performing the recovery: Click here

I couldn't test if it was working in BIOS as well but one thing I found out was that whenever the display flicked the fan would make loud noises. So I guess it is a hardware issue.

I tried updating the bios using the software update provided by HP. It seems to have reduced the noise of the fan. But I can't say so for the display flickering. Since I don't have any another display I can't check for it. Also it is quite random so there is a very low chance that I would get the result instantly.
