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. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected
to the computer.
