    The last week or so, my Macbook Pro has had a strange loud hum that goes off and on. It almost sounds like a small scooter that is revving at high RPMs. It also hums off and on occasionally like it is trying to "start up", almost the way you would start a lawn mower with a hand pull. I apologize for the terrible descriptions but that's all I can come up with. The computer itself seems to be running just fine. Is there anything I can do, any resets or anything? Thanks for the help!

    It sounds

    Like a fan bearing might need checking / replacing.
