MacBook Pro 15" Unibody Mid 2009 I got my new MBP 15" one month ago, I noticed a noise coming from underneath the touch-pad. The noise sounds like a loosy small peice of metal cracking there. When I hear this noise: - when the laptop is on my legs/bed/couch and I move it a little bit. -when I tab on the aluminium around the touchpad. I hear the noise more frequntly day after day... Things are getting bad! I noticed that when I shake the laptop (shuted down) with the lid opened I hear the noise way more than with the lid closed. My laptop is new, its case never opened. I thought of the following: -something wrong with the thing that adjust the touchpad click (if it exists) -there is a free screw moving there (maybe while assembling the laptop they accidentally dropped the screw) -... Is this normal? Should I worry about it? Does it worth it to open the case and see what's going on there?
