Recently, whenever I move my MBP even slightly, I hear this small metallic click on it's left (my right) side. Even if i just adjust it while its on my lap or if i type i can sometimes hear it. IIRC the hard drive is on the other side but I can't remember and haven't opened it up yet. While its on a desk i never hear it so the movement is definitely causing something in there to hit something else...any ideas what it is?
