Replacing the Logic Board

  1. See the following section on compatibility to order the replacement part by EEE code.
  2. If you removed the logic board to access another module, reinstall the board as is. However, if you are replacing the logic board with a new one, notice that a replacement logic board does not include the video card, memory, AirPort Extreme card, Bluetooth card, or IR/ALS components. Make sure these parts are transferred to the new logic board before closing up the computer.
