PowerBook G4 (Gigabit Ethernet) DVD-ROM Optical Drive Replacement Instructions The following instructions explain how to replace the DVD-ROM optical drive in the PowerBook G4 (Gigabit Ethernet) computer. Note: Depending on the configuration of a customer’s computer, the optical drive can be a CD-RW drive, a DVD-ROM drive, or a combination CD-RW/DVD-ROM drive.
Procedure 1. With the computer open and sitting upright, use a black stick to pry up the EMI clip from the rib frame as shown. Reserve the clip for installation of the replacement drive. 2. Important: With the bottom case removed, be careful when turning over the computer. Some components could become loose and fall out. Turn over the computer and carefully pry up the DVD-ROM drive cable connector to disconnect it from the logic board.
3. Locate the metal spacer that fits between the drive and the front bezel. 4. Remove the spacer by flexing the front bezel out while pulling up on the hinged metal spacer. Note: When installing the replacement drive, insert the hooks on the metal spacer into the drive chassis, as shown.
5. Important: To prevent damage to the optical drive, handle the drive only by the corners of the drive as shown by the highlighted safe areas. 6. Gently pull up on the outer side of the drive to remove it. Note: There are four rubber stoppers (two on each side) on the DVD-ROM drive that fit over screws. Remove any that may have fallen off inside the computer.
7. Important: Before installing the replacement drive, ensure that the rubber stoppers are in the correct locations. There are three types of rubber stoppers on the drive. The outer side of the drive has two identical rubber caps that completely hide the screws beneath them.
Important: Verify that the DVD-ROM drive cable does not get caught on the rib frame as the drive is lowered into place. When the rubber stoppers are inserted, push down on the side. Press at all four corners of the drive to verify that it rests flat and is secure. 8. Reassemble and test the computer. Important: Check the operation of the optical drive. If the drive is installed incorrectly, the optical drive mechanism might not spin correctly and will result in mechanical noise when playing a disc.

PowerBook G4 (Gigabit Ethernet) Backup Battery Replacement Instructions The following instructions explain how to replace the backup battery in the PowerBook G4 (Gigabit Ethernet) computer. Tools • Soft towel or cloth, larger than the PowerBook • Black stick (or other nonconductive nylon or plastic tool) Preliminary Steps Before you begin, remove the following: • Battery • Keyboard • Bottom case • Optical drive © 2001 Apple Computer, Inc. All rights reserved.
Procedure 1. Disconnect the backup battery cable from the backup battery. Note: If the cable connector gets caught on the ridged area of the top case, use a black stick to raise up the backup battery and then disconnect the cable. 2. Note: The backup battery is compressed between two thin plastic sheets. The battery is held in place with adhesive on the lower plastic sheet. Slide a black stick under and along the edge of the backup battery.
3. Warning: The ridged area of the top case is sharp. If there is any adhesive left on the surface of the inner top case, use a black stick to rub it away. Do not use solvents. Note: When installing the replacement backup battery, make sure the inner top case is clean and free of debris. 4. Peel off the cover sheet from the bottom surface of the replacement backup battery to expose the adhesive. 5.
PowerBook G4 (Gigabit Ethernet) Logic Board Replacement Instructions The following instructions explain how to replace the logic board in the PowerBook G4 (Gigabit Ethernet) computer. Tools • • • • • Soft towel or cloth, larger than the PowerBook Torx T8 screwdriver Black stick (or other nonconductive plastic or nylon tool) Razor blade Needlenose pliers (optional) Note: To organize the screws you remove from the computer, use a tray with divided compartments (such as a plastic ice cube tray).
Procedure 1. With the computer open, remove the three identical Torx T8 screws that border the memory area of the logic board. 2. Remove the smaller Torx T8 screw near the heat pipe. 3. Disconnect the PC card flex cable connector and the keyed battery connector. Important: If the battery connector has not been disconnected before, the keyed connector may be tight. If necessary, use a black stick or needlenose pliers to loosen one side of the connector and then the other side.
4. Disconnect the shielded, 3-pin backup battery connector from the logic board.
5. Important: With the bottom case removed, be careful when turning over the computer. Some components could become loose and fall out. Warning: The thin cables connected to the LVDS (low voltage data signal) connector are extremely delicate. Do not pull or pinch the LVDS cables. Be especially careful when working near cables that attach to the display. If any of these cables are damaged, the entire display module must be replaced. Turn over the computer so the display rests lightly in your lap.
6. Disconnect the AirPort Card cage connector. 7. Remove the Torx T8 screw at the corner of the logic board. Important: When installing the replacement logic board, install this screw first. This screw helps the logic board align properly to the rib frame. 8. Disconnect the trackpad connector and the hard drive connector. Note: If tape is covering the trackpad connector, reserve the tape for installation of the replacement logic board. 9.
10. Important: With the bottom case removed, be careful when turning over the computer. Some components could become loose and fall out. Tilt up the computer so you can access the EMI clip that secures the optical drive flex cable to the rib frame.

If any of these cables are damaged, the entire display module must be replaced. Warning: At the left clutch, the wrapped cable connected to the LVDS (low voltage data signal) connector is extremely delicate. Do not pull or pinch the LVDS cable. Do not allow the screwdriver to touch the LVDS cable.
7. At the right clutch, note the routing of the inverter cable. Without straining the inverter cable, gently move it aside so you can access the two large silver-colored screws. 8. Support the display as you remove the two identical, large, silver-colored Phillips screws from the right clutch. (Do not remove the smaller screws.) 9. Important: With the display hinge disconnected, support the display as you place it face-down on a soft cloth in front of the computer chassis.
10. Open the I/O door, and remove the four identical Torx T6 screws. 11. Lift out the two back panel mounts from the notches in the rib frame.
12. Remove the four identical black screws from the rib frame. (You might need to move aside the AirPort antenna cable to reach one of the screws.) 13. Lift the rib frame off of the heat exchanger. If the heat exchanger sticks to the rib frame, press gently on the heat exchanger near the two connection points shown. .
14. Disconnect the audio cable at each end of the heat exchanger.
15. Pivot the heat exchanger out of the top case assembly. Be careful where it might catch at the LVDS cable. Warning: At the left clutch, the wrapped cable connected to the LVDS connector is extremely delicate. Do not pull or pinch the LVDS cable. Warning: Do not bend the heat pipe.
16. If replacing the rib frame but reusing the heat exchanger, scrape off the thermal transfer material residue from the area shown. Apply new thermal transfer material to the logic board chip.
17. When replacing the heat exchanger, check that the audio cable is routed as shown. 18. Install the replacement rib frame and/or heat exchanger, and reassemble and test the computer.
