Hi @Jeet_singh,

Thanks for answering!

That's happening in BIOS as well as in any other OS (I have both Windows 10 and Ubutnu), so it's not OS failure. You can see photo of the BIOS screen below.

Regarding the possible hardware issue -- I've already disassembled my HP Pavilion 15-p077sr (J5A69EA), and sometimes it worked, so I believe there is something worng with the screen itself, but I'm not so experiencedin repairs, so I've stopped doing that for now. The screen in question is ltn156at35-h01 btw.

Is that "normal"?  Seems to me it should be prepared to handle that better.
