Hey everyone, when I got my MBP a few days ago, I was standing up with it (still opened) when I heard a short, but acute sound from the right hand side of the laptop: a small spring uncoiling. So it pretty much sounded like a metallic "twang." I opened it up later on and poked around, but couldn't find anything immediate that showed a small spring. And this year's model doesn't have that dual contact spring thing in the middle like the past years did. It hasn't happened again, and at this point I'm growing obsessed with what could have caused the sound, and why. I'm thinking it's the optical drive, since I'm quite sure no hard drive employs a spring to work, not even for SMS. Anyway, if anybody can really help calm my curiosity, I would greatly appreciate it.
