Unlikely cause: power adapter, battery, speakers, optical drive, hard drive, fan, camera,
microphone, top case
Caution: When testing an AirPort card connection, wait at least 5 seconds after shutdown
before touching the camera cable connection to the logic board. Waiting less than that could
damage the AirPort card.
