For the HP ZBook 15 G5, resetting a BIOS administrator password for free is difficult because HP business laptops store security credentials in non-volatile memory that isn't cleared by removing the battery. According to official HP Support, HP cannot reset a forgotten BIOS password; their standard solution is a system board replacement.
However, depending on your specific firmware version and technical comfort, you may try these community-suggested methods. Attempted Free Reset Methods
System Disabled Code (Limited Success): On some HP models, entering the wrong password three times generates a "System Disabled" code. If a code appears, you can try entering it into a BIOS Master Password Generator to see if a bypass key is available. Note that many G5 models do not generate this code.
CMOS Battery Removal (Likely Ineffective): While removing the coin-sized CMOS battery for 15-30 minutes resets basic settings like time and date on many laptops, it generally will not clear the password on enterprise-grade ZBooks.
Hardware Power Cycle: Some users recommend disconnecting the main battery and power adapter, then holding the power button for 20 seconds to drain residual power. While this may resolve boot loops, it rarely clears a set admin password. Advanced/Technical Workarounds

If the code generation fails, the next free option involves hardware manipulation. Warning: This can void warranties or permanently damage your motherboard. Perform at your own risk.
Some HP ZBook 15 G5 motherboards have a password reset jumper (often labeled PSWD or PWD). On the G5, this is usually near the RAM slots or under a small plastic cover.
This involves shorting specific pins on the BIOS chip or the "Password Header" on the motherboard to ground, effectively forcing a reset while the machine is powered on.

Introduction: The Frustration of a Locked BIOS
You power on your HP ZBook 15 G5—a mobile workstation renowned for its power and reliability—but instead of booting into Windows, you are met with a padlock icon or a stark white prompt: “Enter BIOS Administrator Password” or “System Disabled (Code: 887A).” Your heart sinks. You’ve either inherited this laptop from a former employee, forgotten a password you set months ago, or purchased a used unit that is still tethered to its previous owner.
The HP ZBook 15 G5 is a high-stakes machine. It contains your CAD designs, data analysis, or engineering projects. Paying a professional for a reset or replacing the motherboard can cost hundreds of dollars. The good news? A free BIOS password reset is often possible. However, it is not as simple as downloading a "cracking tool." This guide will walk you through every legitimate, free method to reset the BIOS password on your HP ZBook 15 G5—from hardware jumpers to generating unlock codes.

A proven method for many HP business laptops (EliteBook, ZBook) up to 2019-2020 involves:
Requirements:
Process:
flashrom or AsProgrammer.SMC.bin section (HP’s password storage container).hp_bios_password_tools (Python script, open source) or bios-pw online generator (free, no payment) to generate a reset code.Note: This requires opening the laptop, possible desoldering, and risks bricking if done incorrectly.
This is the most legitimate "free" method, provided you meet specific conditions.
The Requirement: You must be able to boot into the Windows operating system with an administrator account. If you are locked out at a black screen asking for a password before Windows loads, this method will not work.
The Process:
BiosConfigUtility64.exe /nspwd:"" /cspwd:"oldpassword"Verdict: Useful only if you are already inside Windows and trying to clear a Setup Password. Useless for a Power-On Password prompt.
