    Hello.
    The sound is coming when mbp were sleeping or turning on and its cold. When its get warmer the sound is stil there but its not so loud. Its not a fan, hard drive or a whining screen, i have already test it. What could it be?
    Thanks

    ps. its seems like coming from the right side of the machine.

    Any chance you could record this for us to hear?

    What kind of sound is it? Is it like the sound a CRT TV makes? It may be the CPU.

    I also suspect you've got the CPU whine--which revision MBP is it?

    Yes...

    I agree with amusiccale... I had a fairly early on MacBook Pro before my current one which was plagued with problems, and one of them was the CPU whine when idle. Horrible high pitched whining would come out from inside whenever the computer wasn't doing much. :rolleyes:
