Es ist nicht erforderlich, IO-Board, Akku und Logic-Board auszubauen. Es genügt, die Antennen- das Kamera- und das Displaykabel zu entfernen und die Scharniere abzumontieren. Die Kabel können leicht an den vorhandenen Komponenten vorbeigezogen werden.

Really great guide!!!

My only issue was the removal of the logic board was a bit nerve wracking.

The speaker wire was stressed heavily as the board tilted up. Removing the speakers before the board would solve this.

I did it in that order during reassembly, and it worked great.

I also had an issue with the logic board installation as the above comment mentioned. I found easiest way is to just remove the speaker that you just re-installed. It's 1 screw - take that speaker out and now that wire that was bumping logic board is out of the way, and just then re-install the speaker.

  • If the heat sink seems to be stuck to the logic board after removing all eight screws, use a spudger to carefully separate the heat sink from the faces of the CPU and GPU.

  • Remove the heat sink from the logic board.

  • When reinstalling the heat sink, be sure to apply a new layer of thermal paste. If you have never applied thermal paste before, we have a guide that makes it easy.

  • These shots show how the rubber fan gasket should be installed during reassembly. Be sure not to install the gasket underneath the ear where the end of the heatsink is screwed down to the upper case.

  • Additionally, be sure the small post molded into the rubber gasket mates with the hole cut into the upper right corner of the logic board.
