    I just got a new 13" MBP. I noticed that there is slight vibration on the right palm rest. I know that the hard disk is located under there but is this normal? Do any of you 13" MBP owners with stock 5400rpm drive feel the subtle vibration in your MBPs?

    Mine has an ultra faint humming feel, but yours sounds more noticeable. You have an awesome warranty. Go here and make an appointment to have it checked out. Can't hurt. :)

    Mines a faint humming too! Is there any other way you would describe it? I mean I can't hear it at all but I can sense the faint humming.

    Are you sure there isn't someone standing in the room humming?

    It could possibly be the fan, or just the hard drive spinning. Do you have this checked?

    Its definitely not the super drive. If I feel the palm rest, I just feel humming sorta feeling.

    I can only feel it when it's sitting on something soft like my carpet.

    Try seeing if the humm goes away by either plugging in the magsafe or unplugging it. Some MBP's give off a small electrical vibration when plugged in.

    As THS says, it may be a grounding (leakage current) issue. Unplug the MBP from the mains and see if the issue remains.

    It exists with or without plugging. I went to a genuis and he said he can't feel anything. I tried the display MacBook and only one of three was similar to mine

    I wouldn't worry. If its the super drive, then that is normal. However, you can always call AppleCare. You're still under warranty.

    The only thing under the right palmrest is the hard disk. It should not be vibrating such that you can hear or feel it without putting your ear close to the surface. My 13" had a similar problem which I noticed a day after purchase. I had Apple replace the disk the following day, and there is now no vibration/buzzing/humming coming from that component. The only thing I can hear is a soft whir from the spindle motor and the quiet clicking of the head servos if I place my ear within a few inches of the palmrest. There is zero vibration that I can feel on the surface.

    EDIT: FWIW, the original noisy drive was a Seagate. The replacement is a Hitachi. From my personal experience, I've had issues with Seagate drives vibrating excessively -- First in my Mac Pro, and now my MBP.

    so when you place your palm on your right palm rest you can even subtly feel anything rotating under it?

    No. I'm using the MBP on a solid wood desk right now, and I can't detect anything vibrating or rotating underneath that palmrest.
