Coin-cell battery

Prerequisite
Before you start, read Appendix A "Important safety information" on page 61 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.
Replacement procedure
1. Remove the computer cover. See "Computer cover" on page 42.
2. Remove the front bezel. See "Front bezel" on page 43.
3. Remove the optical drive. See "Optical drive" on page 44.
