Re: elitebook 850 G7 password

Dear all,

Which chip should be read to remove the BIOS password?

On my HP 850 G7 I have :
- 1 Winbound W25Q80DV at the back of the motherboard
- 1 MXIC MX25L12872F at the back of the motherboard
- 1 Winbound W25Q256JV at the front of the motherboard

Thanks for your help.

Re: elitebook 850 G7 password

Hi,
I read the chip and used RCUnlocker.
It wiped out an 'NvramActiveRegn' section of about 2075 bytes in the bin file at offset 0x37000.
However, it was not able to detect the device type/name/serial...

Is that still OK? Should I resolder the chip back?

Regards,

[FrankTJ]

Re: elitebook 850 G7 password

Hi all,
I soldered the chip back and the laptop cannot boot.
The CapsLock key flashes 7 times then nothing.
Any hint?

Regards,
