    It's prevelant in all processor architectures starting from the 80's I believe. It became much more noticable once processors began to impliment power savings features, and some were able to fix it simply by disabling the C4 state.
    Linky.

    I notice it in my macbook when I boot up into XP, if the power setting is set to portable, but if I set it to "always on", it doesn't happen.

    Check out this video. The person who made it was able to catch it very well.

    No one who has the Unibody Macbook having this problem? I brought it to the apple store but they claim they were unable to hear it. Im going to bring it back another day and try to deal with another "genius"

    I have a ThinkPad T500. I recently noticed this when I went on battery. After doing some research I found that disabling the "CPU Deeper Sleep" option in power management resolved the problem. I don't know if there's anything similar on the Mac side but I would look into it.

    Good luck.

    Yes they will address it.

    HOWEVER, probably not at an Apple Store. The reason is pretty simple: Most maintenance areas of the Stores are too noisy to allow techs to hear the noise.

    If I were you, I'd set up an appointment thorough Applecare specifically indicating that you have a whine, that it is audible in domestic circumstances. The chances are that they'll direct you to an AASP.
