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.
