Hey guys... I'm somewhere I can't immediately take this machine in to an Apple Store (though thank goodness I still have applecare) but I am really scared of this sound I hear every once in a while coming from my 12" powerbook (which I baby and have had for almost 3 years). It is a lateral (left to right) "snap" sound, very physical, almost like a mechanical rubber band -- seeming to come from the front third of the case (near where the trackpad is). It is really, really, TERRIFYINGLY loud. It's happened about five times in a week, for no clear reason, so whatever it is it isn't something that snapped "off" since it's happened more than once. The computer works fine, though I've had strange trouble for a good long time (a few months) where it seems to page out really quickly (I've got a gig and a half of ram, and I really don't remember it paging out so often before). So it runs really slowly at times, and claims a couple hundred thousand pageouts, when I'm not doing anything too taxing-- weird, but not unbearable... So does anyone know what this sound could be? I of course need to take it in to Apple, and my warranty is ironically going to end within the next 3 weeks or so, but I really wonder what could be under there that would create such a racket. Any ideas?
