I noticed after I would shut the lid and I would pick it up or tilt it so it's off balanced I would hear a small noise that sounds like internal hardware, near the Superdrive. Any ideas on what this is? just curious... thanks

edit: it sounds more like a click, then a beep or anything of that nature

It's just the motion sensor parking the hard drive so it won't get damaged. It's normal.

Either that or you are hearing the hard drive as it is writing the hibernation image on the disk. This happens every time you close the lid and put the Macbook to sleep and may take a couple of seconds since it writes 4-8GB of data, depending on how much RAM you have.

That only happens when it goes into safe sleep, which only happens with 5% or less battery. It also does not cause the hard drive to click.
