Carefully lift the battery connector board up off the logic board.
It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.
Do not fold the board completely over, or crease the cables, as this may damage the battery.
Grasp the battery contact board with tweezers.
Lift the battery contact board up off the logic board and remove it.
Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.
Use the flat end of a spudger to pry the right side of the I/O board data cable connector up off its socket on the I/O board.
When prying the I/O board data cable connector from its socket, make sure to pry the connector itself and not the socket. Prying the socket may cause irreversible damage to the I/O board.
Use the flat end of a spudger to pry and disconnect the three antenna cable connectors from the AirPort board.
The three cables are coded with black sleeves of different lengths. During reassembly:
Connect the long-sleeved cable to the center socket.
The short-sleeved cable connects next to the screw.
The remaining cable has no sleeve, and connects in the last empty socket, next to the fan.
