Hi all, Just got my macbook pro unibody. I can hear faint noises coming from the body especially when it is just turned on or just turned off. It sounds like the body is expanding and contracting. The noises are not from one specific spot. They could be coming from the back of the top cover (display) or the area around the track pad or battery. Seems normal to me since aluminum contracts quite a bit especially in relation to glass. Anyone else notice this? Thanks.
