Ouch, no, do not try to remove the battery from the motherboard. It's a good idea if you have an actual PC - but laptops are not meant for easy fixes.

I'm guessing that this wasn't your laptop originally (you bought it secondhand) and that the previous owner neglected to mention the password. How sweet of them.

Personally - I'd type in the name of the BIOS vendor as the password and see if that works.
