HP provides a straightforward method to reset the BIOS password on many of its models, including the EliteBook series.
Without the password, the only officially supported solutions are:
For a work-owned device, contact your IT department. They may have HP's “BIOS Password Unlock” service available with proof of asset ownership.
HP provides a legitimate way to reset the BIOS password—but only to authorized service centers and corporate customers. The tool is not publicly downloadable. However, advanced users have leaked versions or workarounds.
What is it? SMC.bin is a binary file that, when placed on a FAT32 USB drive, resets the SMC and BIOS passwords upon boot.
Requirements:
Process:
Success rate: High (80%+), but obtaining a clean, matching SMC.bin for your exact BIOS version is difficult. Do not download random SMC.bin files from forums—they can brick your laptop.
Once you successfully reset the BIOS password on your HP EliteBook 840 G7, do not let this happen again.

There are dozens of websites claiming to generate an “HP BIOS master password.” Most are scams or malware traps. However, a few legitimate community tools exist based on reverse-engineered HP algorithms (mostly for pre-2019 models).
How it works (legacy): You enter the “System Disabled” code (usually a 5-8 digit number) or the serial number + SKU. The generator outputs several possible passwords.
For EliteBook 840 G7: Due to HP Sure Start Gen6, no public generator consistently cracks the G7’s SMC lock. However, if you only have a Power-On password (not SMC), some older algorithms may still work. Use at your own risk.

Success rate on G7: <5%. This method is largely dead.
If the software methods fail, we must move to hardware. For the HP EliteBook 840 G7, there are three hardware approaches.
If the standard HP tools do not work, a common workaround in the hardware community involves a specific file called SMC.bin. This file acts as a hardware override signal.
