HP Elitedesk 800 G4 DM

[buggbear]

Dear all

I have acquired a 2nd hand HP Elitedesk 800 G4 SSF. I cannot get in the BIOS at all. If I keep hitting F10 it will do one beep and just hang.

I have flashed to the latest BIOS available but no access. BTW, cannot boot into safe mode in Win11. PC will hang. Win11 boots up OK if no attempt to enter BIOS.

I apologize that I don't understand why this is or whether this is the correct forum.

Anybody help please?

You would need an SPI programmer and SOP16 clip https://www.badcaps.net/forum/troubl...21#post1622421

Thanks SMDFlea. I'm afraid it is way over my pay scale.

Thanks anyway.

It does not show error signals .
