Recharging the Battery
To recharge the battery inside the computer, plug in the external power adapter. You may
also use an external battery charger designed specifically for your Macintosh PowerBook
model (available from other manufacturers).
When the AC adapter is plugged in, the LiIon battery is recharged whether the computer is
off, on, or in sleep. However, the battery will recharge more quickly if the computer is off or
in sleep.
Monitoring the Battery Charge
There are four ways you can determine the charge level of your battery:
m Look in the Battery Monitor portion of the Control Strip.
m See low-power messages on your display.
m Look at the battery level icon next to the clock in the menu bar.
m Look at the battery indicator level lights on the battery.

Warning Use only the external power adapter that came with your computer. Adapters
for other electronic devices (including other portable computers) may look similar, but
they may damage your computer.
If your power adapter came equipped with a three-wire grounding plug—a plug that has a
third (grounding) pin—this plug will fit only a grounded AC outlet. If you are unable to
insert the plug into the outlet because the outlet is not grounded, contact a licensed
electrician to replace the outlet with a properly grounded outlet. Do not defeat the
purpose of the grounding plug!
