Are you talking of the BIOS password? Well, turn the laptop upside down and unscrew the plates. Under one of then you will find a button cell about 1 inch in diameter. remove it and reinsert it after five minutes. Your BIOS password will be erased.
If you are talking of the Windows password then you will have to reinstall Windows unless you know thw administrator's password. If you do, then delete this user and recreate it after a reboot. If no, then you must reinstall Window in a directory other than \Windows.
