    Can anyone tell me what is this board in my MBP? I noticed it today when I was taking it apart.

    At the top left of this picture:

    In the middle is the Bluetooth board, and the bottom left is the bluetooth antenna, so it's not either of those. It's not the Airport card either.

    Which MacBook btw? And do you mean the blueish part with REV-A and PBIB0 and 10 scribbled on it?

    Has a www search brought up anything with those numbers?

    It's early 2008, non-unibody.

    Yes, it's the blue board marked Rev. A. The ifixit pictures don't show complete part numbers, and I didn't think to write them down while I had the case open. Mine had slightly different markings, and also said HF.

    This picture has more of the numbers, but is still not complete

    The total length of the board is ~1cm.

    I believe that's the bluetooth module, which is why it has that antenna connector.

    I'm talking about this part. It's not the bluetooth module (which is in the center of the photo in my first post), and it doesn't have an antenna connector. The three wires that run to it are not coaxial, so it is not an antenna itself.

    I believe that is the sensor that detects when the display is closed. Probably a reed or solid state magnetic sensor. There is a corresponding magnet in the display bezel.
