Coin-cell battery

Prerequisite
Before you start, read Appendix B "Important safety information" on page 75 and print the following
instructions.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel connector assignments (configurations). A coin-cell battery keeps this information active
when you turn off the computer.
The coin-cell battery normally requires no charging or maintenance throughout its life; however, no coin-cell
battery lasts forever. If the coin-cell battery fails, the date and time information is lost. An error message is
displayed when you turn on the computer.
