[RESOLVED] Blinking Black Screen in bios

Hi ya’ll!
When in the bios, it blinks in and out with a black screen. This doesn’t stop me from choosing bios options or anything. It also only happens in the bios and not when I’ve booted into Gentoo.
I think this started a few days ago, but I only noticed it after taking the fan assembly off and back on because of having to enter my chassis intrusion password. It was blinking the same in this prompt.
I can’t attach a video, so here’s a gif?

Some things of note:

  • I didn’t replace the factory thermal paste when I disassembled the fan assembly (I’m not good at reading ahead lol), but have some arriving this Thursday
  • It’s an 11th gen with an i7-1185G7 that I got in July of last year.
  • It was on bios version 3.10 when this started. Assuming updating the bios would fix it, I updated to 3.17. (The 3.19 uefi shell hasn’t been released at the time of writing)

In the case of some BIOS updates there has been an issue where only one retimer gets updated. I would verify with fwupdmgr that no BIOS updates are waiting. It may show that your 3.17 update is available, in which case you likely have an incomplete update.

Fwupdmgr doesn’t show there being any available bios updates. And I don’t actually have anything backing my idea that updating the bios would fix this. It started on 3.10 and stayed after updating to 3.17

Please open a support ticket describing your problem and linking this this thread.

After applying new thermal paste, the issue has gone away. I suspect the assembly wasn’t sufficiently tightened, but I’m not sure.
