I've had my Blackbook (2.4 Ghz) for about 3 months now, and i'm not sure if other people have experienced this problem as well, but my panel (the one that is on the side of the Lan port, which covers all the different ports), has become loose. When pressed it makes an annoying squeaking noise. I took it to the apple representative at my univeristy and he was like its normal, and happens over time. His reason for the problem was, that there isn't anything behind it, just a clip so no matter how much you tighten the screws, the thing will still be loose. It made me wonder how apple can do this and still charge a hefty sum ($1500) for its laptops. I would greatly appreciate any advice. Thanks.
