Hardware Symptom Charts

Battery

Battery will not pop up

1. Flip over the unit and slide both battery latches towards the back of the system,

exposing two orange labels. The latches should stay in an open state.

2. If the battery does not pop up, use a small plastic ﬂat-blade tool to pry up the battery

around the battery latch.

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.

Note: The aluminum plate on the battery is a cosmetic cover. The battery is

contained within the plastic housing to which the plate is attached. If the battery is

dropped the plate can deform, especially around the edge near the metal plate. If the

metal plate is bent, use non-marring pliers to bend it back flat.

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.

Note: If there is no sign of abuse (dents, scratch marks) replace the battery under warranty.

5. Try a new battery.

6. Replace bottom case.

The battery won't charge

1. Remove any externally connected peripherals.

2. Try known-good power outlet.

3. Connect known-good 65W power adapter and power cord or plug; make sure the DC

plug is ﬁrmly inserted. The DC plug should light up, if not, replace DC-in board.

If the power adapter light is green, turn over the computer and press the battery

button. The battery lights should glow green and stay on if the power adapter is

operating correctly.

Important: The Apple 65W Power Adapter is highly recommended be used with the

PowerBook G4 17-inch series computers. The adapters can be identified by 65W in

the name and markings, and the metal securing-stud on the plug connector. Although

previous 45W power adapters (see Knowledge Base article 88231 PowerBook and

iBook: Apple Power Adapter) are plug compatible with the PowerBook G4 17-inch

series, it may not provide sufficient power to operate the system during some

activities and may draw power from the battery.
