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?

first boot press f10 apply factory defaults and restart, ..... this works, MPM ... I can also browse the BIOS menu, I couldn't before

2nd boot reset security ...... it won't, it will always ask me for the ADMIN password

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

#97 Is the BIOS that is not needed need the other one from the front of the motherboard ?

[hoaca388]

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.

Post main bios.
