I have a 20" iMac G4, and when it is sleeping or completely off (still plugged in) I can hear a very quiet but audible whining coming from the half sphere base. It isn't something I can hear across the room, but if I put my ear up to the base it is pretty easy to hear. It does not have any other issues. Is this quiet whining normal? Thanks!
