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 "Lithium battery notice" on page vi for information about replacing and
disposing of the battery.
