SOURCE: Reset BIOS password for SAMSUNG NP-SF510 LAPTOP

BIOS passwords can be reset or removed in two ways:

1. using software 2. using hardware.

I would first try resetting or removing using software, here are two software apps to reset or retrieve BIOS passwords.

!BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.

CmosPwd - Cmos password recovery tools

You will need to create a bootable Dos, or Linux or NT cd in order to run them.

Good Luck!
