This article explains how to install an AirPort card in a PowerBook G4 computer.

1. Shut down your computer.

2. Disconnect the power adapter, phone cord, and any other cables connected to the computer.

3. Flip the computer over and remove the battery by sliding the battery release latch, and gently lifting the battery out of the PowerBook.
Warning : The internal components of your PowerBook may be hot. If you have been using your PowerBook, wait 30 minutes after shutting down your computer to let the internal components cool down before continuing.

4. Using a Phillips screwdriver (size 1), remove the eight screws that secure the bottom case of the PowerBook.

5. Carefully slide the bottom case toward you and then lift it up.

6. If your AirPort card came with the AirPort adapter, remove the metal clip and pull the AirPort card from the adapter. (The adapter and metal clip are not used with your PowerBook.)

7. Touch a metal surface inside the computer to discharge any static electricity.

8. Disconnect the AirPort antenna from its holder.

9. Position the AirPort card with the AirPort ID numbers and bar code visible and slide the card into the connector. Make sure to slide the card all the way in until you feel that the card is securely attached to the connector.

10. Connect the AirPort card to the end of the antenna cable. Make sure that the connector on the end of the antenna cable is straight before inserting it into the card. When it is connected, make sure the end of the antenna cable is secured by the small clip shown in Figure 1.
