Changing the battery
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.
