Bios Password enabled without my knowledge

HP Probook 640 g1 password lock on bios. I did not enable this, is there a way to reset/remove the bios lock? I typically keep a log of passwords and none of the ones that I have will unlock the accounts that are listed. There are two users, not sure how the admin mode would have been turned on. Also contacted HP support with no luck. 


I am able to log into the computer just fine, but not bios. Bios asking for admin password. Bios had not previously needed a password at all, but blank and other default passwords don't seem to work.


Very strange behavior.

The BIOS password and Admin passwords are very different situations.


To resolve a forgotten BIOS or power-on password issue, since that password is embedded into the firmware of the system board, to replace that, a system board replacement is required -- and additional customer costs apply, and while the costs vary by laptop model, they are generally around $200 USD. HP has issued this post about BIOS passwords:
