Caution: Due to the enhanced security algorithms on the G2 generation of ProBooks, online generators have a lower success rate compared to older G1 or numeric-only HP models. Method 3: Using the HP BIOS Configuration Utility (BCU)
Found on the bottom cover or inside the battery compartment.

By following these advanced procedures, you can confidently resolve the HP ProBook 450 G2 BIOS password lockout. Remember to always store any new BIOS passwords in a secure, memorable location, and consider setting up HP SpareKey to prevent this issue from recurring.
Alternatively, use to extract the Setup module and look for HP Secure NVRAM . Caution: Due to the enhanced security algorithms on
Because the HP ProBook 450 G2 relies on a dedicated EEPROM chip (often a Winbond or MXIC brand chip) to hold security data, removing the CMOS battery will fail. If software options are exhausted, the password can only be cleared by physically flashing or shorting the security chip.
As of 2026, HP's official stance for business PCs is that they cannot reset a lost or forgotten BIOS password. System Board Replacement : According to HP's official support policy By following these advanced procedures, you can confidently
The ProBook 450 G2, like most business-class notebooks, stores BIOS configuration data and passwords in a persistent EEPROM (Electrically Erasable Programmable Read-Only Memory) chip. This chip does not require continuous power to retain its data. Removing the CMOS battery will affect the system clock and low-level hardware settings, but it will do absolutely nothing to the BIOS password.
Attach the SOP8 clip to the BIOS chip:
. The password is stored in non-volatile memory (firmware) that remains intact even without power. HP Support Community Official Solution: Contact HP Support
On some HP models, entering an incorrect password three times generates an (sometimes starting with 'A' or 'i').
