Apple recommends that you have an Apple-certified technician install memory, PCI expansion cards, and internal storage devices. Consult the service and support information that came with your computer for instructions on how to contact an Apple authorized service provider or Apple for service. If you install these items yourself, you risk damaging your equipment, and such damage is not covered by the limited warranty on your computer. See an Apple authorized dealer or service provider for additional information about this or any other warranty question.

Replacing the Battery

Your computer has a 3.6 V lithium battery installed on the main logic board. Some signs that you need to replace the battery are intermittent problems starting up the computer and random changes in its date and time settings. You can purchase a replacement battery from an Apple-authorized dealer.
    1. Open the computer. See technical document 42687 "Power Mac G4 (QuickSilver 2002): How to Open the Computer" for steps to open the computer.

    2. Remove the battery from its holder, noting the orientation of the battery's positive end. (A plus sign is marked on and near the battery holder). See Figure 1.

    • Remove the battery by pulling it up and out of its holder. You may need to spread these two tabs slightly apart to release the battery. Spread the tabs gently so they don't break.
    • Important: Batteries contain chemicals, some of which may be harmful to the environment. Please dispose of used batteries according to your local environmental laws and guidelines.

    3. Insert the new battery in the holder, making sure the battery's positive symbol aligns with the positive symbol on or near the holder.
    • Warning: Installing the battery incorrectly may cause an explosion. Be sure the battery's positive and negative poles are correctly oriented in the holder. Use only the same type of battery or an equivalent recommended by the manufacturer of the original.

    4. Close the computer

Warning: Never turn on your computer unless all of its internal and external parts are in place and it is closed. Operating the computer when it is open or missing parts can damage your computer or cause injury.
