To respond to a low-battery warning

The computer automatically alerts you when the battery power drops to a critically low
level. First you will hear a high-pitched beep. Then, if you have not taken restorative
action within a short time, the system hibernates.
You won't be able to turn the computer on again until you restore power by one of the
following actions:
Plug in the AC adapter (see "To connect AC power" on page 21).
OR
Replace the battery with one that is charged (see "To install the battery" on page 21).
If you plug in the AC adapter, you can continue to work while your battery recharges.

To optimize battery operating time

Plug in the AC adapter, especially while using the CD-ROM drive or DVD, the floppy
disk drive, or any external connections such as a PC card or a modem.
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 have finished using it.
