I volunteer for a nonprofit that refurbishes and sells donated laptops. We received a large donation but several of the laptops had BIOS passwords.
I have figured out the hard way I can't take the BIOS and EC program out of one laptop and program it into another. That results in "Endpoint Security Controller Problem"
It does fix the password problem.
Here are the original BIOS and EC programs for one of the laptops with a password.
I would like to learn how to remove the password from both files. RCUnlocker doesn't seem to work on these files or I am using it...

HP Zbook 14u G5 SN# 5CG8374M3J Prod ID 5JB73US#ABA REV A01 (Sticker on heat pipe)
Barcode Sticker under DIMM2: 9/13 M/B SPS L14395-601 CS1895
If that isn't what is being asked for please tell me where to find it.
The RCUnlocker does NOT work for this BIOS.
Does the "ME Firmware Cleaning Guide" actually work for removing passwords for this BIOS?
Thank you, -Jay-

I volunteer for a nonprofit that refurbishes computers. A HP Zbook 14u G5 with a password protected BIOS was donated. We will not sell it with a password. Can anyone help me remove the password?
Thank you....

I am a retired electrical/software engineer.

I volunteer for Free Geek Twin Cities. I refurbish donated laptops and install new operating systems. Some systems come with BIOS passwords. We (Free Geek) will not sell systems with BIOS passwords.

I am reading about how to remove BIOS passwords on 2018 to 2021 era HP and Dell laptops. They mostly have WSON 8x6mm BIOS chips.

I would be interested in anyone reprogramming these chips in-circuit. For now it looks like I will need to remove the parts from the board to reprogram them.

Thank you,...
