T61p - bluetooth screw?

[amstel78]

Noticed that when I unpacked my T61p, there was a plastic bag containing two screws. On the bottom of the laptop, there is a screw hole near the right rear side of the laptop with nothing in it.

What are these screws for? I checked the included literature that came with the laptop, and there's no mention of its use.

The short fat one is for securing the optical drive so that a casual passer-by can't eject it easily and take it with them.
The long thin one is for replacing the hard drive cover screw, I think they think that it is harder to remove with a hex-head rather than a cross-head
