I've had a similar experience with certain laptops - an electronic squealing sound that apparently only I can hear. As best I can tell, the sound comes from an inverter connected to the displays.

- kryten 13y agoIt's usually one of two things: 1/ An electromagnetic/mechanical effect in the transformer in the inverter. You can usually stop it by carefully undoing the tape around the transformer and giving it a squeeze. 2/ The audio system is routed next to a bus somewhere and it is just plain old noise being pumped out of the speakers.
