  • Remove the following 14 screws:

    • Six 2.5 mm Phillips on either side of the keyboard area.

    • Five 4.5 mm Phillips on the left half of the keyboard area.

    • One 7 mm hex in the upper left corner of the upper case (a T6 Torx driver will do the job nicely).

    • One 15 mm Phillips in the upper middle of the keyboard area.

    • One 16.5 mm hex in the upper right of the upper case (again, a T6 Torx driver will work well).

  • Peel up the two pieces of foil tape on the left side of the keyboard area.

  • The connectors at the ends of the cables are attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.

  • Carefully disconnect the microphone and power cables from the logic board. Using your fingernails or a dental pick, carefully pry the connectors from their sockets. Make sure you're pulling only on the connector and not on the socket.

At least on my own PowerBook G4 12” 867MHz, the microphone and power cables are long enough that I was able to do the hard drive replacement without disconnecting those connections. I basically had to flip the top case over to the left rather than removing it straight upward. I guess that makes some of the subsequent steps slightly tricky, but at least for me, the tradeoff was worth it.

  • Peeling up yellow tape as necessary, remove the following 8 screws:

    • One 4.5 mm Phillips on the right side of the heat sink.

    • Three 6 mm Phillips near the display.

    • Two large 7.5 mm Phillips with springs (don't forget to remove the springs). If the springs are not releasing, needle nose pliers can help get this done.

    • Two 13 mm screws from the left side of the heat sink and the right side of the fan.

For step 31 I had a problem where the screws with the springs just kept turning. While I did not have this problem the first time I disassembled the board, it was because I did not tighten the screws on the board (the studs on the actual logic board, not the ones you use to fasten the heat sink to the board) before reassembling. If you encounter the same problem, the screws aren't necessarily stripped but the actual piece attached to the board has become loose and just keeps turning. To get them off I used Vise grips and pulled up while turning until i got them off and it took a while. Moral of the story: tighten the pieces actually attached to the board before reassembling. Sorry, I don't know how else to describe the types of screws used but the stud is attached to the board and that is what came loose.

A bit confusing here (and also in the screw guide):

Those four screws in step 41 & 42 are different lengths!

The two shortest ones secure the EMI fingers, the longest one goes under the RJ-11 board and the middle one secures the RJ-11 board.

I had some trouble putting this back together as there was no mention of this...
