Black screen on boot

[Domjos5]

Dear Community and hopefully a HP employee,

I did a recommended update and noticed it said that it would affect the BIOS, and afterward needed a restart.

All seemed well until on the restart the LED's came on (just white, I set mine to purple) which wasn't a good start, after a while of waiting nothing changed. Still just LED's, fans and no beeps. I tried the BIOS reboot suggestions until it came to opening the PC up to restart the CMOS as I still have warranty and don't know if it would affect it going in there myself. 

I've tried contacting hp directly and have only had slight success with a whatsapp representative, but between a busy day isn't very productive. Does anyone have any recommendations of directly calling someone or any other suggestions of a fix?

Thanks for any help 🙂

Hi

I am not an HP employee.

I can say automated: HP BIOS updates or Windows BIOS updates can cause problems.

Try all recovery steps at this HP site: https://support.hp.com/us-en/document/c04126730 

You may have to contact HP Support for factory warranty service, this may not be covered by HP,  if you cannot get a successful POST after following all options at the above link.

Best wishes.
