Replacing the coin-cell battery

Attention: Do not open your computer or attempt any repair before reading and understanding the Chapter
1 "Read this first: Important safety information" on page 1 .
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-connector assignments (configuration). 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, time, and configuration information (including
passwords) are lost. An error message is displayed when you turn on the computer.
To replace the coin-cell battery, do the following:
1. Remove all media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and all cables that are connected to the computer.
2. Remove the computer covers. See "Removing the computer covers" on page 23.
3. Remove the I/O board shield. See "Replacing the I/O board shield" on page 26.
