Forgetting a BIOS password on a high-performance workstation like the HP ZBook 15 G5 can feel like a major disaster. The BIOS (Basic Input/Output System) is the first software that runs when you power on your laptop, controlling hardware initialization and boot order. A forgotten password can lock you out of changing boot settings, disabling secure boot, or even booting from a recovery drive.
Fortunately, there are several methods to reset the BIOS password on an HP ZBook 15 G5. This guide covers official, technical, and hardware-based approaches.
Some technicians use:
Unlike older laptops, the HP ZBook 15 G5 does not use a simple CMOS battery for BIOS storage. The password is stored in non-volatile memory within the Embedded Controller (EC) or Super I/O chip. However, you can attempt to reset it by shorting specific pins on the motherboard.
⚠️ Warning: This method requires disassembly and carries a risk of electrostatic discharge (ESD) or permanent motherboard damage. Only attempt if you have electronics experience.
Steps:
Common pad locations (verify with your board revision):
If you cannot find pads, look for two empty solder points labeled RTC or CLR_CMOS.
