funny vibrations <

my 2009 13 inch mbp has never given me any problems. recently though ive noticed that when i put my palms on both sides of the track pad i feel a slight vibration, like a 'buzzzzing' kind of feel. it almost like theres a cd is in the drive. something ive never felt in the year and a half of owning my mac. i ran a hardware test with my installation cd and the results came back stating nothing was wrong. computer performance is still top notch, im just worried something could be wrong hardware related. again the only reason i question it is because ive never felt the vibration before up until recently. can anyone give me any insight as to what they think it might be?

Probably just the hard drive spinning.

Is it noticeable or just a very slight vibrating?

Well just keep paying attention to it. If it gets really bad, it's probably the hard drive going. I know both sides of my trackpad vibrate constantly, as it's just the hard drive.

Keep current time machine backups.
It could also be the fans ....perhaps a dirt build up inside?
