  9. Use a spudger to pry the fan connector straight up and out of its socket on 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.

I had some problems after I reassemble all the parts, first the Macbook wasn't turn on, but I wait few seconds and it's turn on again. Second the key A on the keyboard not worked but I take off the ribbon cable of keyboard and put it on again and the keyboard worked normally.

This is my comment I hope that help someone.

The computer fell on the MagSafe cable, wich pressed in the MagSafe board (socket) into the body so the cable and the socket couldn't reach contact. From this guide I only did steps 1 to 6 and 17 to 19(only the two screws for the MagSafe board). Then I could move the MagCharger board out enough so it could make contact with the charger cable. Then I tightened the two screws again. Allthou I was as carefull I could with the display data cable (step 17 -18) and looked on youtube allso, it did break a bit at the surrounding solder joint. But it's working. I didn't have to replace the MagCharger board, just move it back into position.
