Recharging the battery
To recharge the battery, plug in the power adapter. (Do not use an external
recharger designed for another Macintosh PowerBook model. Macintosh
PowerBook 5300 series batteries must be charged inside the computer.)
A lightning bolt icon appears in the battery monitor portion of the Control
Strip when the power adapter is plugged in and a battery is recharging.
The battery is recharged regardless of whether you are using the computer, or
the computer is off or in sleep.
WARNING
Use only the 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.
