Traveling with Your Computer Using Battery Power To add additional batteries You can install a secondary battery in either or both of the expansion base's plug-in module bays. See "Using Plug-In Modules" on page 63 for information about installing plug-in modules. To maximize battery operating time Follow these suggestions to make your battery's power last as long as possible. • Plug in the AC adapter, especially when using a drive in the expansion base's module bays, or any external connections such as a PC Card or a modem. • Set the display brightness to the lowest comfortable level (Fn+F1). • Put the computer in Standby mode whenever you are not using it for a short while: press the blue sleep button for approximately one second, or click Start, Shut Down, Standby. • Put the computer in Hibernate mode whenever you want to save your current session, but will not be using the computer for several hours: press Fn+F12. • Set the automatic timeout settings to emphasize saving power. If your computer has a dual-speed processor, use the lower speed on battery power (the default settings conserve battery power). See "How the computer manages power automatically" on page 50. • If you have an I/O PC Card-that is, a PC Card having an external connection, such as a network card-remove it when you're not using it. Some I/O cards use significant power even while they're inactive. • If you work with an application that uses the serial port or an I/O PC Card, exit the application when you finish using it. • Install another battery-see "To add additional batteries" on page 55. • If your main battery is rated at 14.8 volts (check its label), purchase a replacement main battery, which is rated at 11.1 volts.

Using Battery Power
Corporate Evaluator’s Guide

To add additional batteries
You can install a secondary battery in either or both of the expansion base’s plug-in
module bays. See “Using Plug-In Modules” on page 63 for information about installing
plug-in modules.
To maximize battery operating time
Follow these suggestions to make your battery’s power last as long as possible.
Plug in the AC adapter, especially when using a drive in the expansion base’s module
bays, or any external connections such as a PC Card or a modem.
Set the display brightness to the lowest comfortable level (Fn+F1).
Put the computer in Standby mode whenever you are not using it for a short while:
press the blue sleep button for approximately one second, or click Start, Shut Down,
Standby.
Put the computer in Hibernate mode whenever you want to save your current session,
but will not be using the computer for several hours: press Fn+F12.
Set the automatic timeout settings to emphasize saving power. If your computer has a
dual-speed processor, use the lower speed on battery power (the default settings
conserve battery power). See “How the computer manages power automatically” on
page 50.
If you have an I/O PC Card—that is, a PC Card having an external connection, such
as a network card—remove it when you’re not using it. Some I/O cards use
significant power even while they’re inactive.
If you work with an application that uses the serial port or an I/O PC Card, exit the
application when you finish using it.
Install another battery—see “To add additional batteries” on page 55.
If your main battery is rated at 14.8 volts (check its label), purchase a replacement
main battery, which is rated at 11.1 volts.
