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.
