Hi all new member here be gentle lol

I have jumped in here as probably better than starting a new topic,
I have a Probook 640 g1 which is Bios password locked, unfortunately for the moment i dont have the tools to read the existing bios chip.
Is there anyway to flash a new edited (with my serial number, UUID etc) bios over the top of the one installed. If need be will buy a programmer would just be easier for me.

Thanks in advance this Forum is awesome !!

the posted bios is not ok ... try reading the bios chip again and post, make a comparison in the HxD program between a 640G1 bios and the bios posted by you ... see the end ...

The machine now doesnt boot at all, no display and has flashing charge led and solid power light. Think i have bricked it

AsProgrammer looks even more complicated tbh no idea what settings i should use.

Re: Hp probook 640 g1 uma

I just wanted advice on the chip as stated above, Asprogrammer will do me no good as my bios is obviously corrupted now. The machine has no display now and as soon as the battery or power is plugged in the machine powers up but as stated no display or post now and white power light stays solid and charge light flashes orange. Can anyone help ?
