Sometimes while I'm on my macbook pro it makes a little pop sound out of the speakers, then a high pitch sound comes out of the left side of the keyboard like the sound you here when a tv is on but not playing anything. It eventually goes away, but then it happens again. I just got the macbook last saturday. I read up on this but is this a little bit and it seems I'm not the only one... but is there any fix for this??? It is pretty annoying. It also doesn't seem to happen at all so far when the power cable isn't connected..
