18 Chapter 1 Getting Started
If you plan to store your PowerBook for an extended period of time, see “Storing Your
PowerBook” on page 74 for information on how to prevent your battery from draining
completely.
Calibrating Your Battery
To get the longest running time from your PowerBook battery, complete the following
steps during the first week you have your PowerBook.
To initially calibrate your battery, follow these steps:
1 Plug in the power adapter and fully charge your PowerBook battery until the light on
the power adapter plug changes to green and the onscreen meter in the menu bar
indicates that the battery is fully charged.
2 Disconnect the power adapter and operate your PowerBook solely off of the battery.
When the battery gets low, you will see the first low-battery warning dialog on the
screen. Continue to run the PowerBook off its battery until it goes to sleep; at that
point the battery has been sufficiently drained for calibration.
3 Connect the power adapter and leave it connected until the battery is fully charged
again.
Important: You only have to fully discharge and then charge your battery once to
calibrate it. After that, you can connect and disconnect the power adapter when the
battery is at any charge level.
If you purchased additional batteries, repeat the calibration procedure with the
additional batteries as well. For more information about your power adapter and
battery, see “Using Your Power Adapter” on page 23 and “Battery” on page 51.
