Battery
When the external power adapter is not connected, your computer draws power from its
battery. You can determine the charge left in your battery by looking at the battery level
indicator lights on the battery itself. The lights glow to show how much charge is left in the
battery. The indicator lights remain lit for a few seconds after you press the button.
Removing and Replacing the Battery
To remove the battery:
1 Shut down your PowerBook, turn it over, and locate the battery release latch.
2 Slide the latch down and gently remove the battery.
Important If only one flashing light is on, very little charge is left. If no lights are visible, the
battery is completely drained and the computer will not start up unless the power adapter is
connected. Plug in the power adapter for several hours to let the battery recharge.
