SOURCE: how can i unlock dell latitude d420 bios password
Clearing the CMOS will reset the password...
Take the button cell battery out for a few minutes, put it back in, and all settings, including the password, should go back to defaults.
Unfortunately it looks like your BIOS battery is under the keyboard...
Dell has got what looks like decent directions here, for getting at it:
