Tripped over your power cord? At least you don't have to replace the entire logic board.

  • On the keyboard, remove the F1, F2, F11, and F12 keys.

  • This is scary - take a deep breath before continuing. Place your index finger under the upper left corner of the key and lift up until you hear a click. Then, transfer your finger to the left edge of the key and lift up to pull the key off.

  • You're freeing the two tabs on the left of the key from the two small holes in the plastic scissors mechanism.

  • When replacing the keys in the keyboard, place the key directly over the slot where it will go and press down until you hear the key click into place.

  • Grasp the keyboard connector ribbon near the connector and disconnect it from the logic board.

Pull straight up, not sideways. I used tweezers on the connector, rather than pulling on the ribbon cable.

mine had foil tape over the connector

Carefully lift edges of foil tape across logic board connector end of keyboard cable (foil is present if unit

has not been apart before).

Grasp cable near the connector and gently pull straight up (perpendicular to logic board).

  • Turn the computer 90 degrees clockwise and remove the two medium-length Phillips screws from the casing.

  • Turn the computer 90 degrees clockwise again, and remove only the bottom screw on either side of the hinge.

By bottom screw, it means the screw nearer the lid, not the screw nearer the bottom of the computer

  • Turn the computer 90 degrees clockwise just one more time, and remove the two Phillips screws on the exterior wall of the battery compartment.

  • Remember these two screws are longer and have shoulders.

添加评论

  • Turn the computer over and open it up.

  • 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).

添加评论

  • 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.

  • Remove the orange tape on the trackpad side of the fan to free the fan cable.

Remove the silver plate that was under the modem. Gives better access to the orange tape.

  • Grasp the heat sink near the copper conductor and lift it out of the computer, freeing it from tape and cables as necessary.

  • If you need to mount the heat sink back into the laptop, we have a thermal paste guide that makes replacing the thermal compound easy.

  • Remove the following five screws:

    • One 3 mm Phillips near the screen latch (mind the big magnet on the screen latch).

    • Two 3.5 mm Phillips attaching the EMI fingers to the metal framework.

    • One 10 mm Phillips near the optical drive.

    • One 14 mm long 4 mm standoff in the upper left corner. You can remove this standoff either with a 4 mm nut driver or needlenose pliers.

  • Lift the EMI fingers above the battery connector away from the metal framework.

  • Lift up the RJ-11 board from the left side and remove the Phillips screw from the metal framework.

  • Remove the two Phillips screws securing the EMI fingers to the ports.

  • Lift away the EMI fingers.

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...

Thanks for the insight. I'm at this step taking it apart, and will note for future.

  • Once the DC-in board has been removed.

  • Peal back the metal RFI shield.

  • At the back of the power receptacle - gently pull the top of the center tab out away from the receptacle body. Forming a gap.

  • From the front of the receptacle - use a screwdriver to push the broken tip out the gap.

  • Push the center tab back in place.

  • Replace the RFI shield.

Thank you so much for this last step! That's exactly what was wrong with mine. I was going to just replace it until I saw this bit.
