Screen would repeatedly turn dim and turn back on after a while of not being use

[Jorbreezy]

During the past couple months the screen would dim to a point where its basically unable to be seen however, it would occasianlly turn back on after a week or more of not being used. This persists in bios and safe mode. Do I need to replace the screen or the motherboard? 

Product name: HP Omen 15-ax210nr

@Jorbreezy Welcome to HP Community!

I suggest you check with an alternate monitor to confirm the issue, however, if the issue occurs on the BIOS, its most likely a hardware malfunction as you've mentioned, and its either the issue with the system board or the LCD, the external monitor would help us confirm exactly which part has failed, if its the issue doesn't occur on the monitor, its the LCD that hsa failed, that said, here's a few other things you can do, if it turns out to be an issue with the system board:

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

Let me know how that pans out,

Hello, the display had decided to start working again however, I did update my latest bios and according to HP assistant there are no other updates for me to download. When the issue did occure I did run HP hardware diagnostics which it did pass but the problem was still there. I am currently, going to continue monitoring it for the next few days and would contact back if the issue comes back. Thank you for you assistance.

@Jorbreezy The pleasure is all mine, that said, please take your time observing the device and get back to us when you know its up & running for good, or if you need anything else, as well 😉

Take care and good luck.

Good Evening,

A couple months ago I asked a question about my laptop screen repeatedly dimming while it is on and that the only way to see the display was to shine a torch over it. Well the problem decided to come back, and I am not sure why? The Bios is updated and I also ran hardware diagnostics which said there are no problems.
