If your ZBook is part of an organization, it may require a SMC.bin file to unlock, which is a more secure method used by IT departments.
: Plug the CH341A programmer into a second computer and execute a "Read" command. Save this original .bin file twice as a backup.
While standard web-based code generators will not work, there are three free built-in methods you can try before pursuing physical hardware changes or motherboard replacements. Method 1: HP SpareKey Recovery (Built-in Free Tool)
For advanced users: Open the back panel to locate and remove the CMOS coin-cell battery for at least 15–30 minutes. Reassemble and power on the device. HP Support Community 3. Contacting HP Support (Official)

Do not waste time looking for one – it probably does not exist.
You must disassemble the laptop shell to locate the physical BIOS/EEPROM chip on the motherboard.
From within Windows (or a bootable Windows environment), run HP BCU to reprogram the correct system data. This step is critical—without it, some features (including Windows activation and certain drivers) may not function correctly.
Remove it for 5–10 minutes, then reinsert it. Warning: This is less effective on newer G-series ZBooks as passwords are often stored in non-volatile memory. ⚠️ Important Considerations While standard web-based code generators will not work,
The (Universally Unique Identifier), which can be displayed on the BIOS error screen by pressing F1 or F10 at boot.
The BIOS password is encrypted directly inside a physical TPM 2.0 chip or an EEPROM chip on the motherboard.
