I've been trying for hours f10 and factory reset works normally ... The MPM timer always resets after that. I entered all the DMI values from the bios ....
Just reset security ...... it won't, it will always ask me for the ADMIN password..
Can someone calculate the Admin password from the bin file?...

I read it 10 times with asprogrammer and neoprogrammer and it's always the same checksum

I Writte this hp840g9front No Password.bin and the keyboard lit up and blocked everything, only three LEDs above the function keys turned on.
the laptop is stuck there
I will see on Monday to return the original bin

There are two G9 BIOS 25XXX. One on the front and one on the back of the motherboard (when the board is removed and flipped over).
I read this one from the other side.
The small CH361A works well with the new chips with the AsProgrammer.

Need reset BIOS Administrator Password on the HP G9 840
Can it be read using the program or must the flash chip be desoldered? ?
Does anyone know which BIOS flash chip is in the G9 ?

the laptop works
When I enter the bios and want to make settings, it asks for a BIOS Administrator Password

Thanks
