Do not open your computer or attempt any repair before reading and understanding the "Important safety information"

Your computer has a special type of memory that maintains the date, time, and configuration information for
built-in features. The 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.
Before performing the following procedure, be sure to read and understand the information about replacing
and disposing of the battery in the "Batteries" and "Lithium battery notice" sections of the ThinkCentre
Safety and Warranty Guide.
To replace the battery, do the following:
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Remove the computer cover. See "Removing the computer cover" on page 79.
