Battery will not eject

1.Flip over the unit and turn the battery latch clockwise.

3.Verify proper latch operation, by exercising the latch. If it does not move smoothly or evenly, replace the bottom case.

4.If the latch does exercise correctly, verify that the customer is not installing the battery with excessive force or the body of the battery has not been deformed around its perimeter.

Warning: If the battery plastic housing has been damaged, or the two halves of the plastic housing have separated, the battery is unsafe for use.

The battery won't charge

1.Remove any externally connected peripherals.

2.Try known-good power outlet.

3.Connect known-good 65W power adapter (661-3048) and power cord or plug; make sure the DC plug is firmly inserted. The DC plug should light up, if not, replace Sound/ DC-in board.

Although previous 45W power adapters (see Knowledge Base article 88231 PowerBook and iBook: Apple Power Adapter) are plug compatible with the PowerBook G4 (15-inch FW800), it may not provide sufficient power to operate the system during some activities and may draw power from the battery.
