Installing PowerBook G4 Aluminum 17" 1.67 GHz (High-Res) Upper Case

Step 1 Battery



• Use your thumbs to push the two battery retaining tabs away from the battery.
• The battery should pop up enough to rotate it toward yourself and lift it out of the lower case.
Step 2 Memory Door

• Remove the three 2.3 mm Phillips screws securing the memory cover to the lower case.
Step 3
• Lift the memory cover slightly and pull it toward yourself to remove it from the lower case.
Step 4 Upper Case
• Remove the following ten screws:
• Two 14.7 mm shouldered Phillips.
• Three 12.3 mm Phillips.
• One 3.8 mm T8 Torx.
• One 6.8 mm T8 Torx.
• Three 1.3 mm Phillips.
Step 5
• The ZIF cable is located underneath the bottom RAM slot. If your PowerBook has both RAM slots occupied, make sure to remove the RAM chip.
• Use your fingernails to separate the ZIF cable lock away from its socket.
• The ZIF cable lock will move about a millimeter away from the socket before it stops (see picture 2). Do not try to remove the ZIF cable lock.
Step 6
• Use the tip of a spudger to slide the trackpad ribbon cable out of its socket.
Step 7
• Remove the four 3.4 mm Phillips screws from the PC card side of the PowerBook.
• When replacing these screws, you must reinstall each screw in the correct order. Begin by installing the screw closest to the display hinge, and go out from there.
Step 8
• Remove the four 3.4 mm Phillips screws from the DVI connector side of the PowerBook.
• When replacing these screws, you must reinstall each screw in the correct order. Begin by installing the screw closest to the display hinge, and go out from there.
• During reassembly, make sure to reinstall the two screws on the right into their appropriate locations, and not the DVI port anchor holes.
Step 9
• Depress the display latch release button and open your display.
Step 10
• Starting near the display, lift the upper case straight up off the lower case, minding any cables that may get caught.
