I dont think the thread you have sent has the solution for the problem i am facing...

i am facing similar problems this guy in this link is facing:

https://answers.microsoft.com/en-us/windows/forum/all/backlit-keyboard-doesnt-light-up-and-keyboard/4630790d-e923-4e54-b8e7-fdf5e0fc19d6

Plz check this

The only difference between his problem and mine is that i could find the hard disk option in my laptop which a user(mohammed shuaib) was suggesting him to look into while helping him...

I followed his instructions but there was no change... but after a few hours my laptop became normal like always... but i think the problem will still persist... so plz help if you can to put a full stop to this problem. Thank you!

I'm sorry if the steps didn't work. It seems that the issue is complex than what I expected.

It may be best if I release your question to other advisors so they can take a look at it and let them share some other ways that can totally eliminate this issue on your keyboard.

You take care and keep safe always.

Sincerely,
Louie

Thanks, weird. This is a known issue on Windows Insider Dev. Let us see if there is a firmware update available.

Right-click Start>Run.

Type in msinfo32 and press enter.

Take a screenshot of the System Summary window and post it in the next reply.

Sure, thanks. Please update BIOS to F.23 and see if it resolves the problem.

https://support.hp.com/in-en/drivers/selfservic...

Click BIOS and select the setup in the dropdown.

Often these kinds of issues are OS independent and can be resolved by updating BIOS.

Good luck and keep us posted.
