Hi i have a macbook pro 15 inch late 2009 model. Recently i have been hearing a click sort of metallic like sound coming from what i think is the top right of the laptop but not to sure i am pretty sure it is coming from the top half of the laptop near the screen though. This click sort of tink sound is heard when the laptop is moved or if it is sat on my lap. It sounds sort of like when you scroll down on an ipod wheel. The click will also happen once when you click down on the trackpad after it hasnt been used for a while. this click usually only happens once when moved or tilted or when used not on a flat surface but it has made it a few times in a row acouple of times. The click sound also happens when the laptop is moved when turned off. i heard it might be the sms but i disabled it and it still made the noise. can someone please tell me whats the matter with it ?
thankyou
