PowerBook G4 Aluminum 17" 1-1.67 GHz RJ-11 Board Replacement

Orient the computer so that the side with the line of screws on it is away from you.

Use your thumbs to push both battery release tabs away so that the edge of the battery lifts up.

Lift the battery out of the computer.

Remove the three identical Phillips screws from the memory door.

Lift the memory door up enough so that you can get a grip on it, and slide it toward you, pulling it away from the casing.

Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

Pull the chip directly out from its connectors. If there is a second RAM chip installed, pop it out in the same manner.

Loosen the trackpad connector by pulling the locking bar toward the battery housing, using the tips of your fingers.

Slide the trackpad cable out of the loosened connector.

Note: When reassembling the case, the trackpad cable can get stuck below the slot to the motherboard. It's possible to nudge it out slowly by gently prodding it on either side with a small screwdriver. You don't need to use much force to do this. Eventually it will just pop back out and you can reconnect as per the instructions above. Also, note that the locking bar comes loose so if you see a little piece of plastic lying around when reassembling, that's what it is. :)

Remove the following 10 screws from the bottom case:

Three 1.7 mm Phillips from the front edge of the battery compartment.

One 3.9 mm T8 Torx to the right of the memory card.

One 6.9 mm T8 Torx at the left edge of the memory compartment.

Three 12.4 mm fully threaded Phillips from the center of the row of screws along the back edge of the case.

Two 15.1 mm 2.5 mm threaded Phillips, one from either end of the row of screws along the back edge of the case.

Open the computer and turn it so that the screen faces you.

Pull the upper case off, lifting from the back, and working around the edges.

Use a spudger to loosen the casing if it sticks.

Once the casing is entirely free, lift it off of the computer.

Use the method described in the step for disconnecting the keyboard ribbon to loosen the connector on the DC-In board.

Pull the cable free of the loosened connector.

Remove the single Phillips screw from the Bluetooth board.

Lift the Bluetooth board partially out of the computer and disconnect the attached antenna cable.

Disconnect the black speaker cable from the sound board.

Remove the single T8 Torx screw from the left speaker assembly.

Disconnect the orange DC-In cable from the logic board.

Deroute the cables from the right side of the speaker and lift it off of the logic board.

Disconnect the rainbow power cable from the DC-In board.

Disconnect the black and white RJ-11 cable from the top, right corner of the modem.

Remove the two identical T8 Torx screws from the DC-In board.

Slide the DC-In board to the right and lift it out of the computer.

Your laptop should look approximately like this.

Use your thumbs to slide the RJ-11 board away from the sound card. This is your chance to get out some aggression, as the board will most likely be very tight and require a good deal of force to remove. Don't get carried away though - don't torque the ambient light sensor and don't put too much actual force on the card itself.
