Corrupted Bios - Recovery

[Johnjs123456]

Due to some problems that i had with charging and thought that it was bios problem i decided to update it. I downloaded the recommended version (sp92961.exe) for my model, flashed it in a usb drive and forced the update. During the process the laptop restarted and suddenly powered off (possibly due to the charging problem).

Since then, when i try to power on, i get black screen, no keyboard lights, no sounds or beeps, and i hear only the fan.

I tried almost every method to recover bios with no luck. I used keyboard combination win + B or win + V with or without a flash recovery drive with the bios installed, removed RAM and removed cmos battery. Nothing worked.

During my attempts to recover it, i solved the charging problem by removing battery with charger and holding the power button for some seconds.

Is there any suggestion to recover or to flash bios?

Hi! @Johnjs123456,

Thanks for writing to us.

Create a USB recovery drive and try performing a BIOS recovery.

Download the latest version of BIOS using this link. Click Here

Install a BIOS recovery file from the HP website using a USB flash drive. To complete this step, you need a second working computer with an active Internet connection.

Hi! @A4Apollo

Thanks for your answer.

Although i had already done the steps you proposed, i repeated them again. The result is the same.
I think that no key combination is going to work as i don't get any light on my keyboard which may means that is inactive.

Hi! @Johnjs123456,

Thanks for writing back to us. It certainly sounds like the BIOS on the PC has been corrupted.
