In the area of computer security, there are three methods of access control: what you know, what you have and what you are.
What you know = a password
what you have = a keycard
what you are = your face or fingerprint (the biometrics)
To have vastly improved security, you require two or all three of these categories (called two (or three) factor authentication)
In this case of having the fingerprint scanner, that's still just one of these categories, so it's more of a case of security theater. Two factor authentication would be first pressing your thumb on the pad, verifying, then entering in a password. I dunno, maybe that's how most laptops are already set up, but from what's been said in this thread and what I know (very limited), it's still only a single factor.
And, as has been said upthread, having physical access to the box... eventually it's a done deal, unless the person has some other more extreme data-protection measures set up.
