Removing a Pre-boot Authentication System

Alright, so recently I handed a locked computer that was protected by a pre-boot authentication system. The person who locked it is long gone and I don’t know the administrative code. I can, however, log onto the computer with my co-worker’s finger print. I have the computer in safety mode, but how do I remove the pre-boot authentication system? Here’s what I’ve tried: 1) Removing the BIOS battery 2) Service Tag (expired) Help would be great! Thanks

Software/Hardware used:
Dell D820

Thanks. We'll let you know when a new response is added.

Using your co-workers fingerprint, and able to boot, try utilizing this product to erase the CMOS/BIOS.
