    Pop and then high pitch noise
    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..

    not exactly the same problem you are having but could be a similar issue and worth checking. look at my post here and see if this might be related to your problem.

    I get a small pop occasionally too...

    but it seems to go away when I turn the volume past 7 squares (and the sound isn't overpowering the pop, the pop happens before sound comes out)

    is this the case when you plug it in everywhere or do you normally plug it in to the same place?

    hahahaha

    i meant into the same outlet or on the same circuit of outlets.

    there are many things that can travel at a 60hz range within a given circuit in a home that can cause interference such as what i mentioned in my link above with the tv cable line.

    this is a common problem with lots of homes and many devices but is most noticeable with speakers and some times video.

    i was just trying to give some suggestions that might help you solve your problem.

    i will just let you handle it then since you must know what your doing since you posted for help here.

    well the way you said it was kind of confusing . If you had said. Do you plug it in different places on the wall, or the same place all the time.

    I do plug it in in different places.

    so you plug it in at other places and it always makes this noise no matter where it is?

    if this is the case and it doesnt happen when it is not plugged in then it would have to be something related to charging. is there any chance you could get your hands on another power cable to test if it is possibly related to a faulty power cable?

    this makes me think that the noise happens when it is charging and stops when its full and so on. just guessing here but this could be possible.
