Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-port assignments (configuration). A battery keeps the information active when you turn
off the computer.
The battery normally requires no charging or maintenance throughout its life. However, if the battery fails,
the date, time, and configuration information (including passwords) are lost. An error message will be
displayed when you turn on the computer.
Refer to “Lithium battery notice” in the Safety, Warranty, and Setup Guide for information about replacing
and disposing of the battery.
To replace the battery, do the following:
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
