  • PowerBook G4 Aluminum 12" 1-1.5 GHz EMI Finger Replacement

    Dear powerbookg4hdd. This is a very long screw and you could not drill it out. First, try to turn it with needle-nose pliers. If that is too difficult, use a larger drill bit and try to drill the head completely off instead. You're in a very difficult situation. Of course, remove the RAM card to give yourself some working space.

    Add a "good quality silver-based thermal paste" to the list of tools required. See step 25 and here:

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Logic Board Replacement

    When you remove the logic board, note that there is an EMI finger surrounding the connectors on the left side. Now here is the important part: When reassembling, remember to reinstall this EMI finger!

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Heat Sink Replacement

    They say "peel" because it is stuck with adhesive.

    The middle of the three 6 mm screws (orange circles) is hiding under the cable. Actually you need to do step 24 first, so you can access it.

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Upper Case Replacement

    This is not as easy as it looks. You see the four slots in the picturer there -- the two on the end are partially covered by the technician's left and right thumbs. Those are attached to plastic clips that need to be disengaged. You can access the two inside the batter compartment and disengage them using a small flat-head screwdriver, but the two on the left are not accessible. I finally got them to disengage by pulling up near the trackpad.

    In the picture, the foil is already gone. If your computer has been taken apart previously, as apparently ours has, the foil may be already gone. The photo is missing the markers that are needed to see what they are talking about, but these two connectors are near the left side. The speaker cable has a red and black wire, and the microphone connector has three grayish white wires.

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Keyboard Replacement

    I would not pull up on the ribbon as is being done in the picture. Note that the black pastic base that you see is the connector part that is permanently attached to the ribbon cable. Use a small screwdriver or spudger alternately on each end of the black plastic base to pry and rock it upwards.

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Airport Extreme Card Replacement

    Note that this is a "right angle" coaxial connector. The metal cube is a part of the connector and stays with the cable. It is not a part of the airpor card. Also, I found two clear plastic blocks in front of the airport card, a smaller one near the connector and a larger one on the other side. Possibly these are to keep the cable from vibrating and flexing during, say, a truck ride. Don't lose these.

  • PowerBook G4 Aluminum 12" 1-1.5 GHz Heat Sink Replacement

    Not sure what they mean by "thread it around". I would say that you simply lift it up a little so that you'll be able to slide the heat sink assembly out from under it in the next step.
