For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary but it prevents any accidental shorting of electronics on the motherboard. If you do not disconnect the battery connector, please be careful as parts of the motherboard might be electrified.
Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.
It is useful to pry upward on both short sides of the connector to "walk" it out of its socket.
Use the flat end of a spudger to disconnect the left fan connector from the logic board.
It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.
The fan socket and the fan connector can be seen in the second and third pictures. 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.
Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer.
Pull the display data cable straight out of its socket on the logic board.
Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.
Carefully lift the logic board assembly from its left side and work it out of the upper case, minding the optical drive cable and the I/O ports that may get caught during removal.
If necessary, use the flat end of a spudger to separate the microphone from the upper case.
Pull the I/O port side of the logic board away from the side of the upper case and remove the logic board assembly.
