Battery

Attention: Do not open your computer or attempt any repair before reading and understanding the "Read
this first: Important safety information" on page v.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-connector assignments (configuration). A battery keeps this information active when you
turn off the computer.
The battery normally requires no charging or maintenance throughout its life; however, no battery lasts
forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An
error message is displayed when you turn on the computer.
Refer to the "Lithium coin cell battery notice" in the Safety, Warranty, and Setup Guide for information
about disposing of the battery.
