BIOS passwords can be reset in two ways,
1. using software  2. using hardware.

first try resetting using software, here are two software's to reset or retieive BIOS passwords.

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

CmosPwd - Cmos password recovery tools 4.8
Link : http://www.cgsecurity.org/index.html?cmospwd.html

Now try resetting hardware method. there are two ways 2 do it 1. u just need to take out the battery, and Press the on/off button for 5seconds, the 2nd is more drastic u need to disassemble all parts and take off the small battery (its even in PCs) and hold it for ten minutes, then its going to be OK ( I suggest you do the second way, because the first way works only on some notebooks)

in modern laptops, the password is not kept in the bios, but in a security chip.  (Anti-theft)
you need to contact the manufacturer, and show proof of ownership
for the login password, try this one : http://home.eunet.no/pnordahl/ntpasswd/
you can also find it on the ubcd : http://www.ultimatebootcd.com/

Once you've gotten the BIOS password bypassed:  This site allows you to download files needed to create a bootable floppy disk or CD-ROM which contains a program that can be used to reset passwords on a Windows NT-based OS (such as WinXP and Vista):

Offline NT Password & Registry Editor

It is a rather "geeky" tool; not a nice Windows graphical user interface.  You might want to check this page for a demonstration of its use, with screenshots provided in the article:
