Replacing the battery

Attention:
Do not open your computer or attempt any repair before reading and understanding "Important Safety Information"
on page 1.
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 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.
