hey guys, sorry for my poor english, I'm a french speaker ahah. I just bought the new mid 2012 Macbook Air 3 days ago and today when I moved the computer it did that crazy weird grinding noise coming from the fan almost like when you move a laptop while there is a CD in it. it can be easily reproduced by leaning the computer on the side or moving it fast (although not every time). I was wondering if I was alone with that problem. I'll call apple tomorrow morning to know what can be done.
