Report: HP ZBook 15 G5 BIOS Password Reset Procedures

Subject: BIOS Password Removal/Reset Options for HP ZBook 15 G5 Date: October 26, 2023 Status: Informational / Technical Guide

Prevent Future Lockouts

  • Save passwords in a password manager (e.g., Bitwarden, 1Password).
  • Record the UUID and unlock code from HP support for future use.
  • Disable BIOS password unless required for security compliance.
  • Enable HP Sure Admin (available on G5 and newer) – allows password recovery via a digitally signed token.

Legitimate Options

  1. HP Support – If you own the device, contact HP with proof of purchase. They can provide a master password or service override.

  2. System Board Replacement – HP's official solution for forgotten BIOS passwords is replacing the motherboard (under warranty if applicable). hp zbook 15 g5 bios password reset

  3. Password Jumpers – Unlike older laptops, the ZBook 15 G5 does not have a simple CMOS reset jumper. The BIOS password is stored in non-volatile memory (EC/EEPROM).

Part 5: Using "HTTP Boot" and HP SureStart to Your Advantage

The HP ZBook 15 G5 includes a unique feature: HP SureStart – a self-healing BIOS. If the BIOS is corrupted, it restores from a golden copy. You can trigger a "recovery" that might reset the password. Report: HP ZBook 15 G5 BIOS Password Reset

How to force SureStart recovery:

  1. Power off completely.
  2. Press and hold Windows Key + B (both keys).
  3. While holding, press and hold the power button for 2-3 seconds, then release only the power button.
  4. Continue holding Win+B until you see a blank screen flashing, then a BIOS recovery menu.
  5. Select "Recover BIOS defaults" – this will not clear the password in most G5 units, but on pre-2019 firmware, it sometimes cleared the admin password as a side effect.

4) CMOS/BIOS hardware‑level reset (advanced — opens the laptop)

Note: ZBook 15 G5 uses internal soldered motherboard components; procedure varies by model/revision. Prevent Future Lockouts

  1. Power down, unplug, remove bottom cover and disconnect internal battery and AC adapter.
  2. Locate and remove the RTC/CMOS coin-cell battery (if accessible) or disconnect the RTC/BIOS battery cable — on many ZBooks the cell may be soldered or in a holder.
  3. Wait 10–30 minutes (some recommend longer) to discharge CMOS.
  4. Reinstall battery, reconnect internal battery and AC, reassemble and power on — check BIOS access.

If BIOS password persists, the motherboard may store password in non‑volatile memory requiring service.

2) Use HP official support/service

  • Contact HP support with proof of ownership; they can provide authorized service or instructions.
  • If under warranty or with an authorized service center, they can remove or replace the BIOS/CMOS module.
