    I meant to ask this a while ago, but just getting to it now. My powerbook makes this very weird nose that I find not only annoying, but concerning. Whenever I move my mouse around, it sounds like the HDD begins doing some action and it makes a noise similar to running disk utility. Also when I have the screen open and if I carry the powerbook, say for example of I want to hand it to someone or show them something, a medium to high pitched noise comes on again emanating from the HDD area. What the heck is going on?:confused:

    I know it's not the most exciting question, but I could really use some input here.

    How old is the PowerBook? It could be the hard drive and the motion sensor making that noise, if it's a newer model. Does the sound disappear when you mute your speakers? :)
