So I was writing a paper with the computer on my lap, then moved it with the lid still open to my desk, but as I was lifting it up I heard a very audible clicking noise. I attempted to repeat the experiment and found that my MBP will make a distinct single click when lifted suddenly upwards with the screen open. The noise comes from the right side, I assume from the super drive. Does the super drive have a sudden motion sensor like the HD, or is this something else? The noise never happens when the laptop is stationary, only like I said, when open and lifted straight up suddenly. EDIT: I guess it happens with the lid closed, but after a few times, it stops doing it . What the **** is this noise?
