try it dude i'm not sure if my 32mb modification would work i just copy paste binary from files i compared. but the 16mb would work fine in bios password.
flash both files and in first boot press f10 then disable absolute in bios security. then reformat, then use MPM tool just search here in forum.

Re: HP 840 G7 password

Hello all,

Having trouble resetting this bios password. I used the flash utility. The 16MB says it flashed but when I tried the 32MB it says to revert back to flashing with the 16MB.

Unfortunately, the bios password is still locked, even though it says the 16MB worked. I just dragged the .bin file into the utility, then restarted the laptop.

Here's the laptop's info:

SKU Number: 1C8P3UT#ABA

UUID: 9B385AC018701FE17EEECC8450FF9475

UUID (standard format): C05A389B-7018-E11F-7EEE-CC8450FF9475

Asset Tracking Number: 5CG0292MKL

Feature Byte: 3X476J6S6b7B7H7M7Q7W7m7saBapaqauawb8bUbhcAdUdpdqfAfPgSguhKjhk8mE.HM

System Board ID: 8723

System Board CT Number: PJRZQ00WBDY6RA

Any help would be greatly appreciated! Thanks in advance!

I looked through the beginner's guide on here but didn't see how to extract the bios from the laptop to upload it. Can you point me in the right direction? Sorry man, I'm a total noob at this.


I also forgot to include the motherboard model number. Pictures are attached.

Thank you Vesko. I've attached the .bin file. That's the 16MB, as I was unable to extract the 32MB (not sure if it even has one?).

Hi, can you help me remove the administrative password on Elitebook 830 G7 ?

I watched a video and the person in the video said Winbond 25Q128JVPQ chip contains the lock. Leave the other chip alone.

I have attached my original BIN to this message.

Serial# 5CG1048WZX

Thank you.

There's no admin password set in the attached main bios dump, it is your original backup or not?
What's the laptop serial number, is it 5CG0466LL9?
Upload a screenshot of the password prompt screen.
