Replacing the coin-cell battery
Attention: Do not open your computer or attempt any repairs before reading the Important Product
Information Guide.
Note: 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 dispose of the coin-cell battery, refer to the "Lithium coin-cell battery notice" topic in the Safety and
Warranty Guide.
To replace the coin-cell battery,
1. Remove the computer cover. See "Removing the computer cover" on page 23.
2. Remove the front bezel. See "Replacing the front bezel" on page 23.
