Replacement Instructions
Follow the instructions in this sheet carefully. Failure to follow these instructions could
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
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
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.

6. Remove the battery by sliding the battery latch to the left. Make sure to return the latch
fully to the right.
(Figure 2)
Removing the battery will prevent you from accidentally turning on the computer.

Removing the Installed AirPort Card
1. Pull back on the antenna clip
(Figure 7B)
2. Pull the card from the AirPort connector
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

4. Plug the antenna cable connector
located just below the plastic tab
(Figure 11A)
(Figure 11B)
into the port on the AirPort Card,
. 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
6. Fold the plastic tab

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.
Note:
The screws must go in straight and easily; if they do not, readjust the bottom
(Figure 12)
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.
