ciao grazie dell'aiuto ,ma non vanno per me ,connetto l'alimentazione .i led lampeggiano alternativamente giallo/bianco per qualche secondo ,come se stesse facendo un check ,poi si accende tutto e si rispegne tutto ,poi lampeggia bianco/giallo ogni tanto a intermittenza

Hi, thanks for the help, but they don't work for me. I connect the power supply. The LEDs flash alternately yellow/white for a few seconds, as if it were doing a check, then everything turns on and off again, then it flashes white/yellow intermittently every now and then.

in English please.....

Hi, I have an HP EliteBook 840 G4

I think the BIOS is corrupted. I'm attaching the original BIOS reading on the card, hoping for your help.
Thank you so much....
