Calibrating Your Battery for Best Performance
To get the longest running time from your PowerBook battery, let the battery run down
completely during the first week you have your PowerBook. Then fully charge it one time.
Follow these steps:
1 Plug in the power adapter and fully charge your PowerBook battery until the battery
indicator lights and the onscreen meter indicate that the battery is fully charged. A green
light on the power adapter plug also indicates that the battery is fully charged.
2 Disconnect the power adapter and use your PowerBook. When your battery gets low, you
will see the first low battery warning dialog on the screen. Continue to use your PowerBook
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.
Connecting the Internal Modem
If you want to connect to the Internet right away, connect one end of the included phone
cord to the modem port (marked with the icon
W ) on the left side of the computer, and the
other end to an analog telephone line (the type of telephone line found in most residences).
When you turn on your PowerBook for the first time, a Setup Assistant walks you through
the rest of the steps necessary for connecting to the Internet. For more detailed information,
see Appendix C, “Connecting to the Internet.”
Important You have to fully discharge and then charge your battery only once to calibrate
it. After that, you can connect and disconnect the power adapter when the battery is at any
charge level.
Warning Do not connect a digital telephone line to the modem, because the wrong
type of line could damage the modem. Contact your telephone service provider if you
are unsure whether you have a digital telephone line.
