Trying to reset the admin password

[Leon_Schnider]

Hi, I’ve bought a laptop that asks for an admin or a power on password once turned on, the old owner provided me the right password, I logged into bios to remove this option as I don’t need it, used the old password given as the old password, then I left the ( new password + the confirmation fields) empty ,… saved and exit, now the laptop still asking me for the password and won’t accept the old one or the ( empty ) password I applied,.. any help please 😞

BIOS (and Power-On) passwords are encoded into the firmware on the motherboard and we have no access of any kind to that.

There is no MASTER BIOS password that works on all PCs or even on all HP PCs. That is an "urban legend" that is simply untrue. If there were such passwords, they would have been posted on the Internet and there would be no value in setting BIOS passwords.

Removing or replacing the BIOS chip does not reset the password, nor does removing the CMOS battery, nor does shorting out the CMOS battery leads.

HP policy is NOT to reset BIOS passwords on existing motherboards.
