    • Loosen the four silver Phillips screws that secure the RAM shield.

    • These screws will not come out all the way. The screws are held captive to the RAM shield to prevent them from getting lost.

    • Breathe deeply. Trying times are ahead, but we promise the lower case does come off.

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

  12. iBook G4 14" 1.42 GHz Top Shield Replacement: step 12, image 1 of 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.

    • 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.

  14. iBook G4 14" 1.42 GHz Top Shield Replacement: step 14, image 1 of 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.

  15. iBook G4 14" 1.42 GHz Top Shield Replacement: step 15, image 1 of 1
    • There are three tabs over the optical drive that must be released before the lower case can come off. Slide the spudger into the lower case above the optical drive and run it toward the back of the computer until you hear three distinct clicks.

  16. iBook G4 14" 1.42 GHz Top Shield Replacement: step 16, image 1 of 1
    • The front and sides of the lower case are now free.

    • Angle the DC-In board out of its compartment.

    • You may need to remove tape that secures the DC-In board cable to the case.

  22. iBook G4 14" 1.42 GHz Top Shield Replacement: step 22, image 1 of 1
    • Lift the DC-In cable from the adhesive attaching it to the logic board.

  23. iBook G4 14" 1.42 GHz Top Shield Replacement: step 23, image 1 of 1
    • Disconnect the DC-In cable from the logic board.

    • Wiggling the connector parallel to the surface of the logic board while applying slight tension may aid in removal.

  24. iBook G4 14" 1.42 GHz Top Shield Replacement, Upper Case: step 24, image 1 of 1
    • Remove the following 11 screws from the bottom of the computer:

    • Three 3 mm Phillips around the battery compartment.

    • Four 14.5 mm Phillips.

  25. iBook G4 14" 1.42 GHz Top Shield Replacement: step 25, image 1 of 1
    • We recommend placing the computer on a soft cloth from this point on to prevent damaging the logic board.

    • Turn over the computer and open it.

    • Remove the 3 Phillips screws from the edges of the keyboard area.

    • The shorter screw goes in the lower left corner. The left corner is indicated by a blue "L" in the photograph and is on the right side.

  26. iBook G4 14" 1.42 GHz Top Shield Replacement: step 26, image 1 of 1
    • Be especially careful while disconnecting the cables in the forthcoming steps. Never pull directly on the cables, but use a spudger to pry up the connector directly from its socket.

    • Lift the upper case and use a spudger or your finger to disconnect the trackpad connector hidden beneath the white plastic tab.

    • Be careful while lifting the upper case, as its tabs are still hanging on the metal frame.

  27. iBook G4 14" 1.42 GHz Top Shield Replacement: step 27, image 1 of 1
    • The sockets attached to the motherboards of most iBooks are very weak and easily broken. Use extreme caution when pulling connectors out of their sockets.

    • Lift the upper case enough to disconnect the blue and white power cable from the logic board. Using your fingernails, carefully pry the connector from its socket.

    • Carefully disconnect the multicolored speaker cable from the logic board in the same fashion.

  28. iBook G4 14" 1.42 GHz Top Shield Replacement, Top Shield: step 28, image 1 of 1

Before you start dis-assembling anything with screws this small and numerous and of various sizes, purchase some double-sided tape, and stick the screws to it in groupings that will have meaning to you when you re-assemble. My groupings frequently simulated the orientation of the screws in the related picture.
