damage your equipment and void its warranty.
Note: Written and video instructions covering customer-installable parts are available at
http://www.info.apple.com/installparts/.
Warning: Sharp edges can exist inside your computer and on any parts being
removed or installed. Use caution to avoid injury.
During this procedure, keep small parts away from children.
Tools Required
• Soft towel or cloth, larger than the PowerBook
• Torx T8 screwdriver
Removing the Bottom Case
Warning: Always shut down your computer before opening it to avoid damaging its
internal components or causing injury. After you shut down the computer, the
internal components can be very hot. Let the computer cool down before
continuing.
1. Place your computer on a clean, flat surface.
2. Shut down your computer and wait thirty minutes before continuing.
3. Disconnect the power cord and any other cables connected to the computer.
4. Place a towel or soft cloth on a table in front of you. (Figure 1A)
The towel or cloth will protect the keyboard and display area of the PowerBook when
you flip it over to remove the battery and bottom case. Make sure it covers an area
large enough for your PowerBook and that it hangs over the edge of the table.
5. With the display open at an angle greater than 90 degrees, carefully flip the
PowerBook over and lay it flat, fully on the table. Make sure the display hangs over the
edge of the table and rests lightly on your lap. (Figure 1B)
Important: Do not open the display farther than the angle shown.

case, then press down slightly to secure the case. Check the alignment of the seven
screw holes to make sure the bottom case is properly positioned.
Important: Make sure that the seams between the bottom case and the frame are
closed. Check the outside edges and around the battery well. Verify that the
alignment tab on the underside of the bottom case (Figure 6A) has seated, and the
case lies flat.
2. Replace the seven screws in the order shown. (Figure 6)
Note: The screws must go in straight and easily; if they do not, readjust the bottom
case for proper alignment. Do not overtighten the screws or damage could result.

• Torx T8 screwdriver
Opening the Computer
Warning: Always shut down your computer before opening it to avoid damaging its
internal components or causing injury. After you shut down the computer, the
internal components can be very hot. Let the computer cool down before
continuing.
To access the AirPort Card, you must first remove the battery and bottom case.
1. Place your computer on a clean, flat surface.
2. Shut down your computer and wait thirty minutes before continuing.
3. Disconnect the power cord and any other cables connected to the computer.
4. Place a towel or soft cloth on a table in front of you. (Figure 1A)
The towel or cloth will protect the keyboard and display area of the PowerBook when
you flip it over to remove the battery and bottom case. Make sure it covers an area

Figure 5
10. Touch the computer’s inside framework (a dull gray conductive composite material) to
discharge any static electricity, as shown. (Figure 6)
Important: To avoid electrostatic discharge damage, always ground yourself by
touching the computer’s framework before you touch any parts or install any
components inside the computer. To avoid static electricity building back up in your
body, do not walk around the room until you have completed your installation and
closed the computer.

Removing the Installed AirPort Card
1. Pull back on the antenna clip (Figure 7A) to release the antenna cable connector
(Figure 7B) and allow the card to rise up slightly.
2. Pull the card from the AirPort connector (Figure 7D).
3. If there is tape securing the antenna cable to the AirPort Card, carefully remove it and
store it in the battery compartment for reuse later. When installing the replacement
AirPort Card, use the tape to secure the cable in the same manner.
4. To disconnect the antenna cable connector, hold the AirPort Card with one hand and
grasp the antenna cable connector with the other. While being careful not to strain the
antenna cable (Figure 7C), firmly pull the connector straight out of the AirPort Card.
Figure 7

B
Important: If reassembling the computer without an AirPort Card, replace the
antenna cable connector into its holder (Figure 9B) and pull the loop of the antenna
cable up slightly and away from the edge of the computer case. This prevents the
cable from interfering with the PC card slot, below, or getting pinched during
reassembly.
Also, if the AirPort Card connector (Figure 7D) is rotated up, push it down into the
level position. This allows the bottom case to install properly.
PowerBook G4 (1GHz/867MHz) AirPort Card- 5
Installing the Replacement AirPort Card
1. If the replacement AirPort Card came with the AirPort adapter (Figure 8A), remove
the metal clip (Figure 8B) and pull the AirPort Card (Figure 8C) from the adapter.
(The adapter and metal clip are not used with your PowerBook.)
Figure 8

2. If necessary, pull the AirPort antenna cable connector (Figure 9A) from its holder
(Figure 9B).

3. Position the AirPort Card (Figure 10B) with the AirPort ID numbers and bar code
facing up. Pull up the insertion end of the AirPort Card connector (Figure 10A) slightly
and slide the card all the way into the connector until it is securely attached.
Figure 10

A
PowerBook G4 (1GHz/867MHz) AirPort Card- 6
4. Plug the antenna cable connector (Figure 11A) into the port on the AirPort Card,
located just below the plastic tab (Figure 11B). Make sure the connector is straight
before inserting it into the port.
Note: If tape was removed earlier, use it to secure the antenna cable to the card.
5. Push the AirPort Card down until the antenna cable connector is secured by the small
antenna clip (Figure 11C).
Important: Route the antenna cable (Figure 11D) between the edge of the computer
and the AirPort Card. Verify that the cable is away from the edge of the computer so
that it will not be pinched during reassembly and that it does not sag down into the
PC card slot area (below the AirPort Card). Take up any extra cable by tucking it in
where shown (Figure 11E).
6. Fold the plastic tab (Figure 11B) on the AirPort Card over the top of the card.
Note: The plastic tab must be folded over the card during the installation of the
bottom case; otherwise you will not be able to securely attach the bottom case to the
computer.

Closing the Computer
1. To attach the bottom case, align the notches on the right and left sides of the case,
then press down slightly to secure the case. Check the alignment of the seven screw
holes to make sure the bottom case is properly positioned.
Important: Make sure that the seams between the bottom case and the frame are
closed. Check the outside edges and around the battery well. Verify that the
alignment tab on the underside of the bottom case (Figure 12A) has seated, and the
case lies flat.
2. Replace the seven screws in the order shown. (Figure 12)
Note: The screws must go in straight and easily; if they do not, readjust the bottom
case for proper alignment. Do not overtighten the screws or damage could result.
Important: To avoid damaging the case, be careful that the screwdriver tip does not
slip out of the screw head during tightening.
