Sadly there is little you can do to get rid of the Bios password. I'm replying to this, knowing that you won't like to be told this and in all probability leave me an "unhelpful" award. However, and after trying about every approach I could a few years ago to get past the Bios password, eventually gave up. I'd rather save you the hassle I went through.
There are a number of people who will offer (at a price) to remove this for you. I seriously doubt they can do it. The only real solution, is to have the bios chip replaced by a professional, or replace the motherboard. Note that often, even if you get past the bios pass, the hard drive may be locked in a similar fashion, this cannot be removed, and the hard drive will not reformat even if done externally.
If you want to have a go, and you know WHICH bios is on the laptop, you can try the software on this site (which is what most of the so called "bios hackers" who will charge you money for this, get their codes from).
