Notebook doesn't start

[Alfaface]

Hello everyone, I have read several articles in the forum and cannot find an answer that solves the problem
I am facing the problem and understand that it happens to other users.

I have a HP 17-cp0255ng in an automatic Windows update the PC wouldn't turn on again and 
The screen went black, I tried the suggested solution of window + B and updated with flash boots 
from a mustard pipe. .. the problem persists, it tells me there is an error in the BIOS and 
I can't access it with Esc, F10, etc. The screen is still white, black, no picture, no.

I understand you are facing a Laptop not turning on with your HP 17.3 inch Laptop PC 17-cp0000 (2Q7W8AV). Not to worry I will help you to get a resolution to resolve the issue.

None of that helped. The laptop doesn't boot. This doesn't work with a boot stick either. Incorrect bios version. There are two BIOS updates F 30 this one doesn't work. F12 means you can't create a boot stick via the HP site
