First check this site to see if your HP is supported for the great tool Mazzif has made.

http://mazzifsoftware.blogspot.com/p...os-unlock.html

If your model is newer and not in that list, you need to dump your bios, remove password from dump and reprogram bios with modified dump.

For that you need an SPI programmer like CH341A or Raspberry Pi with Flashrom or any other similar programmer. A soic8 clip is also useful so there wouldn't be a need to unsolder bios IC.

When you have your dump, just drag and drop your file on my HPUnlocker tool and it will create a new file. It will add "_unlocked" to the name of your locked file.

Just program the new file on your bios IC.

This unlocker should work on all Elite, EliteBook, ProBook and maybe some other series HP laptops.

For those of you who need to unlock large amounts of laptops, I recommend adding a registry entry:

Computer\HKEY_CLASSES_ROOT\*\shell\HPUnlocker\command

Then modify that string adding

"C:\*location-of-exe*\HPUnlocker.exe" "%1"

This way you just need to right click your locked file and select HPUnlocker.

If there are any issues, please do let me know so I can improve this tool.

All Elitebooks, Probooks and zbooks which are up to ninth generation which should be up to year 2018, like 840 G5, are supported. Newer models are not supported (yet atleast).

No Pavilions or other trash is supported

NEW multitool and unlocker added .

Unlocking
HP - ProBook, EliteBook, ZBook (including 32MB models)

Hello!
Finally this BIOS worked, thank you very much.

P.S: It would be wise to keep in mind that under certain circumstances both utilities fail to edit the locked BIOS. Unfortunately i don't know the exact circumstances but i'll keep the locked BIOS stored in case someone wants to run some research.

Thank you again!

Are you sure it has a password

Well yes, when i try to enter BIOS it asks for fingerprint OR password, if i press Esc it asks me if i want to enter as Guest.
Also the RCunlocker confirms there's a password and that password is removed.
I upload screenshot and original bios it self.
Thank you in advance

Ok now i'm into a very weird situation.
I backed up the bios from a 650 G1, i drag into this tool and RCUnlocker too, the result is that both the original dump and the patched (from both tools) are identical!
I compare them with HxD
How is this even possible? I feel super dumb right now.

doesn't work hp elitebook 840

[rolodog]

Hi, Sorry to keep asking questions but I still have an issue. The bios that you sent have worked perfectly and I no longer have a admin password. The issue now is I can not load windows onto the machine. The original that was on and also via trying a new install both fail. Any suggestions.

once again thanks for all your help

Hello, have been working on a 650 G2 Bios locked Admin Password and think I finally got it but wish to be positive. All worked as described in the forum with some trials. Used a EZP 2019+ programmer but had to modify it for the ground pin as stated. Also, could not get the programmer to identify the Winbond W25Q128FVSO with the power supply connected and laptop off. Once it was unplugged the programmer identified it as Winbond W25Q128 and I took 4 reads and verified all, they were all the same then used HxD to compare all files were the same. Please have a look at the attached files and let me know if they seem OK to write.
