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.
Refer to “Safety notices (multi-lingual translations)” on page 97 for information
about replacing and disposing of the battery.
