步骤 6

Use the tip of a spudger to push the camera cable's plug toward the fan and out of its socket on the logic board.
The plug in the photo has six connections, but some models have twelve connections. The process of removing the plug from its socket is the same for both.
If the camera cable's plug won't come easily out of its socket on the logic board, fold back the rubber cover over the fan to gain access to the cable, then gently pull on the cable while using the spudger to gently push the plug out of its socket.
Be sure to push parallel to the board, first on one side, then the other, to slowly "walk" the plug out of its socket. Do not pry up, or you will damage the socket.
