Are you locked out of your HP ZBook 15 G5 laptop due to a forgotten BIOS password? Don't worry, this article will guide you through the process of resetting the BIOS password and getting back to using your device.
What is a BIOS Password?
The BIOS (Basic Input/Output System) password, also known as the UEFI firmware password, is a security feature that protects your computer from unauthorized access. It's a password that's stored in the motherboard's firmware, and it's used to prevent others from accessing your computer's settings or booting from unauthorized devices.
Why Reset the BIOS Password?
You may need to reset the BIOS password if:
Preparation
Before attempting to reset the BIOS password, make sure you have:
Method 1: Resetting the BIOS Password using a Key
HP provides a simple way to reset the BIOS password using a special key combination. Try the following:
Method 2: Resetting the BIOS Password using a Backdoor Password

HP ZBook 15 G5 , there is no manual "backdoor" or universal master password to reset a forgotten BIOS administrator password. Because this is a business-class mobile workstation, security is embedded directly into the firmware, meaning standard methods like removing the CMOS battery or shorting jumpers will HP Support Community Official Solution
HP's official policy for business notebooks is that you must contact HP Customer Support to resolve this issue. HP Support Community Proof of Ownership
: You will typically be required to provide the device's serial number and valid proof of purchase. SMC.bin File : In some cases, HP support may provide a customized
file. This file is loaded onto a USB drive and used during bootup to temporarily bypass the password. Motherboard Replacement

While it rarely clears a set administrator password on G5 models, you can try a CMOS reset to fix other startup issues: Connect the laptop to an AC adapter Turn off the computer. Press and hold the Windows key + V While holding those, press the Power button for 2–3 seconds.
Release the power button but continue holding Windows + V until the CMOS Reset screen appears or you hear beeps. Third-Party Options HP ZBOOK 15 G5 BIOS PWD - HP Support Community
The HP ZBook 15 G5 is a powerhouse workstation, but getting locked out of the BIOS can bring your productivity to a screeching halt. Whether you inherited a device with an unknown password or simply forgot your own, resetting the BIOS password on this specific model is more complex than on older laptops. If you want, I can:
Because the G5 series utilizes advanced security chips, the traditional "remove the CMOS battery" trick no longer works. This guide explores the legitimate methods to regain access to your system. Understanding HP's Modern Security
On older hardware, clearing the CMOS memory usually wiped the BIOS password. However, the HP ZBook 15 G5 stores security credentials in non-volatile memory (TPM chip). This data persists even if the laptop is completely depowered for years. This is a theft-deterrent feature designed to keep professional data secure. Method 1: The HP SpareKey Recovery
If you or the original owner set up HP SpareKey when the laptop was first configured, you are in luck. This feature allows you to recover your password by answering three personal questions.
Turn on the laptop and press F10 repeatedly to enter the BIOS Setup.
When prompted for a password, look for a "SpareKey" option or press F11.
Answer your pre-set security questions (e.g., "What was your first pet's name?").
If successful, the BIOS will grant access and allow you to set a new password. Method 2: Contacting HP Support (The Official Route)
For Enterprise-grade machines like the ZBook, HP provides a service to generate a SMC.bin file. This is a personalized unlock key linked to your specific UUID and Serial Number.
Requirements: You must provide proof of ownership (invoice or receipt). Process: Contact HP Customer Support.
They will ask for your Serial Number and UUID (found on the BIOS lock screen). HP sends a file named SMC.bin via email. Copy this file to a FAT32-formatted USB drive.
Plug it into the ZBook, hold Windows Key + Up Arrow + Down Arrow, and power it on.
Note: HP has recently tightened restrictions on this service for older out-of-warranty models, but it remains the safest official method. Method 3: BIOS Password Reset Jumpers
The ZBook 15 G5 motherboard contains a specific jumper meant for clearing the "Power-On Password." While this may not always clear the "Administrator Password," it is worth attempting before seeking hardware replacement. Power off the laptop and remove the bottom cover. HP ZBook 15 G5 BIOS Password Reset: A
Disconnect the main battery and the small coin-cell (CMOS) battery. Locate the jumper labeled PSWD or PASS on the motherboard.
Move the jumper cap from its current position to the reset position for 10 seconds. Move it back, reconnect the batteries, and boot up. Method 4: Replacing the BIOS Chip or Motherboard
If the software methods fail and you cannot provide proof of purchase to HP, the final options are hardware-based.
EEPROM Programming: Advanced users use a "CH341A Programmer" to physically clip onto the BIOS chip and flash a "clean" BIOS file. This requires technical expertise and carries the risk of bricking the device.
Motherboard Replacement: This is the "nuclear option." Replacing the entire system board will provide a fresh BIOS with no password, but it is the most expensive route. Summary Checklist 💡 Quick Tips for Success: Always try common default or "forgotten" passwords first.
Check if the keyboard layout is correct (Z and Y are swapped on some layouts).
If you bought the device used, contact the seller for the "Management Password."
To provide more specific steps, I'd need to know if you can still boot into Windows or if the laptop is completely locked at the start.
For some laptops, resetting the CMOS (Complementary Metal-Oxide-Semiconductor) can reset the BIOS password. This involves opening up your laptop, locating the CMOS battery, and removing it for a few minutes before reinserting it. This method should be approached with caution and may void your warranty.
If your HP ZBook 15 G5 is still locked after all attempts, you have one nuclear option: replace the motherboard.
However, a creative workaround exists: Swap the EC/KBC chip.
On the G5, the password is stored inside the Nuvoton NPCE388N embedded controller, not the main SPI BIOS chip. You can:
This requires advanced rework skills (hot air station, stencil, leaded solder). Many repair shops will do this for $150–$250, far cheaper than a $900 motherboard replacement.
