Attach the test clip to the BIOS chip, ensuring Pin 1 (marked with a dot on the chip) matches Pin 1 on the programmer. hp probook 450 g2 bios password reset
Good luck, and may your ProBook boot freely once again.
If the above fail, the password resides on a dedicated security chip. This method is risky.
However, this method is not guaranteed. The tool notes that "Newer laptops... are currently not supported," but the 450 G2 falls within the supported timeline.
You will likely need to provide the serial number (found on the bottom of the laptop) and the System Disabled code. Enter the 8-digit code exactly as it appears
To receive support, the user must provide . HP will verify the serial number and the user's identity.
