Changing the top case will also give you a new trackpad.

    • Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.

    • If the keyboard does not come free, use a small flathead screwdriver to turn the keyboard locking screw 180 degrees in either direction and try again.

    • Flip the keyboard over, away from the screen, and rest it face-down on the trackpad area.

    • If the computer does not have an Airport card installed, skip the next two steps.

    • Push the wire clasp toward the Airport card and pull it up to free it from the RAM shield.

    • Your laptop should look approximately like this.

  10. iBook G3 12" Upper Case Replacement: étape 10, image 1 de 1

  11. iBook G3 12" Upper Case Replacement: étape 11, image 1 de 1

    • Use a spudger or small flathead screwdriver to pry up the three metal rings that housed the rubber bumpers.

  13. iBook G3 12" Upper Case Replacement: étape 13, image 1 de 1
    • Remove the one 10 mm and two 20 mm hex screws using a 2mm hex. Alternatively, a T8 Torx screwdriver key will do.

  14. iBook G3 12" Upper Case Replacement: étape 14, image 1 de 1
    • Remove the two 4.2 mm Phillips screws on either side of the battery contacts.

  15. iBook G3 12" Upper Case Replacement: étape 15, image 1 de 1
    • Breathe deeply. Trying times are ahead, but we promise the lower case does come off.

    • Push the thin rims of the lower case surrounding the battery compartment in, bending them past the tabs, and then lift up to free that corner of the lower case.

  16. iBook G3 12" Upper Case Replacement: étape 16, image 1 de 1
    • There is a slot on the wall of the battery compartment that locks the lower case in place. Use a small flathead screwdriver to pry out the slot's lower rim and pull up on the lower case to free the slot from the tabs holding it.

  17. iBook G3 12" Upper Case Replacement: étape 17, image 1 de 1
    • Run a spudger along the seam between the lower case and upper case on the front of the computer to free the tabs locking the lower case. Pull up on the lower case and continue to use the spudger as necessary until you hear three distinct clicks.

  18. iBook G3 12" Upper Case Replacement: étape 18, image 1 de 1
    • Continue to run the spudger around the front, right corner. There are two tabs on the port side of the computer, one near the front corner and one near the sound out port.

  19. iBook G3 12" Upper Case Replacement: étape 19, image 1 de 1
    • Once the front and sides of the lower case are free, turn the computer so that the back is facing you and pull the lower case up and toward you until the back tabs pop free (it may be helpful to jiggle the case up and down).

  20. iBook G3 12" Upper Case Replacement: étape 20, image 1 de 1
    • Remove the small greasy springs with white plastic caps from either side of the battery contacts.

  21. iBook G3 12" Upper Case Replacement, Upper Case: étape 21, image 1 de 1
    • Remove the following 4 screws on the bottom of the computer:

    • One 4.5 mm Phillips near the latch mechanism (this screw may be missing in 800 MHz iBooks)

    • One 14.2 mm Phillips near the front, right corner.

  22. iBook G3 12" Upper Case Replacement: étape 22, image 1 de 1
    • Use a straightened paperclip to open the optical drive tray.

  23. iBook G3 12" Upper Case Replacement: étape 23, image 1 de 1
    • Pull the optical drive out just enough so that you can access and remove a Phillips screw near the battery compartment.

  24. iBook G3 12" Upper Case Replacement: étape 24, image 1 de 1
    • Pull the optical drive a bit more so that you can access and remove a second Phillips screw near the power receptacle.

  25. iBook G3 12" Upper Case Replacement: étape 25, image 1 de 1
    • Turn over the computer and open it.

    • Use tweezers (or a refrigerator magnet) to remove the magnet covering a Phillips screw near the middle of the computer.

  26. iBook G3 12" Upper Case Replacement: étape 26, image 1 de 1
    • Remove the following 4 screws on the edges of the keyboard area.

    • One 4.5 mm Phillips underneath where the magnet was.

    • Three 6 mm Phillips in plastic depressions.

  27. iBook G3 12" Upper Case Replacement: étape 27, image 1 de 1
    • Peel up the foil tape covering the speaker cable near the ports.

  28. iBook G3 12" Upper Case Replacement: étape 28, image 1 de 1
    • This is a diagram of the trackpad ribbon clamp connector you will disconnect in the next step.

    • 1) With your fingernails, grasp the locking bar on either side and pull up a small amount (about 1/16" or 2 mm).

    • 2) After disengaging the locking bar, slide the cable out of the connector.

  29. iBook G3 12" Upper Case Replacement: étape 29, image 1 de 1
    • Loosen the trackpad connector by pulling the top piece up slightly, freeing the trackpad ribbon.

    • Slide the orange trackpad ribbon out of the connector.

  30. iBook G3 12" Upper Case Replacement: étape 30, image 1 de 1
    • Before you can jerk the upper case off with joy, you must disconnect both the blue and white power cable and red and black speaker cable as described in the next steps.

    • Lift the upper case from the left side and use your other hand to pull out the right side in order to clear the power receptacle.

    • There may be a thin metal bar fastened to the upper case by the two screws on either side of the optical drive. This bar provides rigidity around the optical drive; don't forget it when reassembling.

  31. iBook G3 12" Upper Case Replacement: étape 31, image 1 de 1
    • 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.

    • Lift the upper case enough to disconnect the blue and white power cable from the logic board. Using your fingernails or a dental pick, carefully pry the connector from its socket. Make sure you're pulling only on the connector and not on the socket.

  32. iBook G3 12" Upper Case Replacement: étape 32, image 1 de 1
    • Lift the upper case off completely and disconnect the red and black speaker cable from the logic board. As before, make sure you're pulling only on the connector and not on the socket.

  33. iBook G3 12" Upper Case Replacement: étape 33, image 1 de 1
    • There is a magnet that allows the computer to detect when the laptop is closed. If this magnet is not present your computer will not automatically go to sleep. Be sure the magnet is in the position indicated.
