Re: hp elitebook 840 g4 need password unlock
Hey guys. I'm new to this forum, and from what I've read I should be able to complete this. However, do you guys have any advice for expediting the process? I recently acquired hundreds of these laptops all bios locked. Any advice would be appreciated.Comment

Re: hp elitebook 840 g4 need password unlock
Hello,
Unfortunately, each bios in those laptops is unique, so no, you cannot expedite the process. The only way of accelerating process is to have the password, which I guess is impossible, but worth asking... Hopefull the one that sold you the laptops have the password, or can ask the password from the enterprises he gets them from.
A way to accelerate things though, is to remove the password yourself from the files, which is possible, by removing some binary data and replacing it by 0xFF or 0x00 at certain places.
Process is:
- Remove the bios chip
- Read it and make sure your read it well
- remove the password
- write the new bios in it
- resolder it back
For hundred of laptops it will be painful, but after getting used to the process, you will be able to treat one laptop in 30 minutes.
Good luckComment

Re: 840 G4 6050A2854301-MB-AO1 bios lock
Hello members, I have the same problem as all of you. My BIOS is locked. I need to unlock it. I have backup file, from my BIOS IC, which is MX25L12873F.
BIOS backup file you can find here. Can unlock that file and write the steps for additional tasks to do that everything work well. As I understand correctly, you have to do more that overwrite BIOS file.Last edited by SMDFlea; 04-10-2023, 12:39 PM.Comment

Re: hp elitebook 840 g4 need password unlock
Do I have to make dump of the EC bios as well if the laptop is "Protected by HP Sure Start".
Or is a dump and password removal of the main bios enough?Comment

I have a Inspiron 11 3185, and in the BIOS setup under Security it shows "Locked Setup", which limits pretty much everything in the BIOS. I'm using bios-pw.org to generate the codes for the hash, but they never work for the Locked Setup password. The codes generated for the System password and the HDD password work fine, but the code for the Locked Setup password always fails. I don't understand, if it works for the first two, why is it not working for the Locked Setup p/w? Since I can't disable it, anytime I reboot, even after a Windows update, I have to go through the hassle of generating... -

Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...
