Replacing the battery

Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as parallel-port assignments (configuration). A
battery keeps this information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life;
however, no battery lasts forever. If the battery fails, the date, time, and
configuration information (including passwords) are lost. An error message is
displayed when you turn on the computer.
Refer to the "Lithium battery notice" in the ThinkCentre Safety and Warranty Guide
for information about replacing and disposing of the battery.
To replace the battery:
1. Remove the computer cover. See "Removing the cover" on page 11.
2. Locate the battery. See "Identifying parts on the system board" on page 9.
3. Remove the old battery.
