    • Use a coin to turn the battery locking screw 90 degrees to the right.

    • Lift the battery out of the computer.

  2. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement, EMI Finger: Schritt 2, Bild 1 von 1

    • Remove the long black Phillips screw next to the memory card.

    • Remove the small EMI finger beneath the black screw.

  4. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement, Keyboard: Schritt 4, Bild 1 von 1
    • 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.

    • Remove the two short Phillips screws.

  7. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 7, Bild 1 von 1
    • Lift the keyboard by the 'esc' and 'eject' keys and gently lift up until the keyboard is vertical.

  8. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 8, Bild 1 von 1
    • Grasp the keyboard connector ribbon near the connector and disconnect it from the logic board.

  9. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement, Upper Case: Schritt 9, Bild 1 von 1
    • Remove the three small Phillips screws from within the battery compartment.

  10. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 10, Bild 1 von 1
    • Turn the computer 90 degrees clockwise and remove the two medium-length Phillips screws from the casing.

  11. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 11, Bild 1 von 1
    • Turn the computer 90 degrees clockwise again, and remove only the bottom screw on either side of the hinge.

  12. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 12, Bild 1 von 1
    • 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.

  13. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 13, Bild 1 von 1
    • 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).

  14. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 14, Bild 1 von 1
    • 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.

  15. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 15, Bild 1 von 1
    • Use the orange plastic loop to disconnect the trackpad cable.

  16. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 16, Bild 1 von 1
    • Starting at one of the upper corners near the screen, work around the frame, separating the upper case from the lower case.

  17. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 17, Bild 1 von 1
    • Lift the upper case off the computer.

    • Deroute the cable connecting the reed switch board to the DC-to-DC board.

  19. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 19, Bild 1 von 1
    • Disconnect the reed switch cable from the DC-to-DC board.

  20. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement, Hard Drive: Schritt 20, Bild 1 von 1
    • Remove the two Phillips screws from the hard drive bracket.

  21. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 21, Bild 1 von 1
    • Use the orange plastic loop to disconnect the hard drive cable from the logic board.

  22. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement: Schritt 22, Bild 1 von 1
    • Use the orange cable to pull the hard drive up, then pull it and the hard drive bracket out of the computer.

  23. PowerBook G4 Aluminum 12" 867 MHz DC-to-DC Board Replacement, DC-to-DC Board: Schritt 23, Bild 1 von 1
    • 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.
