• Before proceeding, power down your MacBook. Close the display and lay it on a soft surface, top-side down.
• Use a P5 Pentalobe driver to remove ten screws securing the lower case, of the following lengths:
• Two 9 mm screws
• Eight 2.6 mm screws
Step 2

• Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.
• Remove the lower case and set it aside.
Step 3 Battery Connector
• As a precaution against accidental discharge or shock, disconnect the battery connector from the logic board.
• Grab the clear plastic pull tab attached to the battery connector and pull it toward the front edge of the Air to disconnect the battery from the logic board.
• Be sure to pull the connector horizontally toward the battery, and not straight up from the Air, or you may damage the socket on the logic board.
Step 4 I/O Board Cable
• Use the flat end of a spudger to pry the I/O board cable connector upward out of its socket on the I/O board.
Step 5
• Carefully peel the I/O board cable from the top of the fan.
Step 6
• The following connector has an especially deep socket. Use care when disconnecting it.
• While gently pulling the I/O board cable upward near its connection to the logic board, use the tip of a spudger to pry upward on alternating sides of the connector to help "walk" it out of its socket.
• Remove the I/O board cable.
