Replacing the coin-cell battery
Attention: Do not open your computer or attempt any repairs before reading the Important Product
Information Guide .
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, 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,
1. Remove any media from the drives and turn off all connected devices and the computer. Disconnect all
power cords from electrical outlets and disconnect all cables from the computer.
2. Remove the computer cover. See “Removing the computer cover” on page 19.
