I have noticed that once every 6-7 weeks or so I hear a weird noise coming from the area of the disc drive. It sounds like it starts up, clicks, and then stops. It last maybe 2-3 seconds. Is this something I should be worried about? Should I bring it by Apple? I've been figuring that since it only happens randomly they won't be able to check anything. Also, how hot the Macbook Pro get? Sometimes I feel like it's smoking hot if I use it on my lap. To the point that if its on my skin I usually put something under it.
