I just purchased my Macbook Pro about a week ago, and I am having some trouble with it. Inside the right palmrest, I keep hearing 'tinks'. Almost sounds like lose hardware, but I don't think that is the case. Also, when I am playing a video in VLC, if I move the Macbook, or adjust its positioning, that 'tink' will happen, and it will freeze the video for a second. Any idea why? I have been reading about a security feature inside of it, but its sort of an annoying noise.
