46 Chapter 3 Using Your Computer
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, or replace the drained battery with a fully charged battery (see the
next section).
If the battery icon in the Finder menu bar is set to show the percentage of charge, you
may sometimes notice that the battery does not maintain a full charge of 100% when
the power adapter is attached. When the battery level eventually drops below 95
percent, it will charge all the way to 100 percent. This saves battery life as charging is
not continuously cycled on and off.

m
Shut down your iBook G4. Turn it over and locate the battery latch. Use a coin to turn
