Procedure

1.With the preliminary steps completed, compare the original top case to the replacement top case.

2.Before installing the replacement top case, make sure it includes the following:

Speaker set and cables

Power button and board (heatstaked to top case)

AirPort antenna cable

Trackpad assembly with board and cable

3.Important: Make sure you transfer the original serial number label from the old top case to the serial number panel on the replacement top case. You can use a black stick or razor blade to carefully peel up a corner of the label. Then peel off the label completely and apply it to the serial number panel. Make sure that the label lies completely flat so it does not interfere with the battery compartment.
