Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

The instructions say, in order to reassemble, just reverse the steps. However, they do not say what adhesive to use for the microphone, or how to properly position it against the frame. Is Barge's Cement adequate?
