Hi.

I've used HPunlocker multiple times and never had a problem. Now I'm trying to unlock the 840 G5, the program generates the _unlocked file but after playing it to memory the password is still there. will you help?

Upload the dump from the second bios chip.

It's not a good approach to solve the matter in this case.

Does anybody know how to activate the manufacturing program mode (MPM) of an 840 G5 Motherboard. I need to change the system unique data after replacing the motherboard.

Many thanks

Maybe I'm blind, but the HP BIOS update tool only shows me two options.
Update or create a recovery flash drive.

Did you read the Post? You should to use a Hardware Programmer in order to take a Backup for your BIOS Chips (Main & EC).

Re: Hp ellİtebook 840 g5 bios password

Hi there! I am attempting to remove the bios password from a decommissioned Elitebook 840 G5. I came across post #56 of this thread which fit my laptop's criteria exactly, and followed the directions offered by the response in post #57. I used a ch341a with the BIOS chip soldered onto the adapter to read and verify the original bios and then used the HPUnlocker v1 program to generate the unlocked bin file (both attached here). I rewrote the unlocked file to the chip and then soldered back into place on the motherboard.

After putting it together, I'm now experiencing an issue where the capslock button light and power button are flickering (see image ezgif-2-da60db5cdd.jpg). I read that this might be an indication of a bios corruption and I tried to do the Win+B during startup to see if it would reset it, but to no avail. I'm hesitant to desolder and reflash the bios again due to how difficult it was for me to get it back into place, but I will do it if it means I'll have a working laptop again.

If anyone could provide me guidance, I would greatly appreciate it. Thanks for your time.
