Replacing the battery
Important:
Before you replace any FRU, be sure to read and understand Chapter 1 “Safety information”
on page 1.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features,
such as parallel-connector 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 coin cell battery notice” in the
Safety, Warranty, and Setup Guide
for information about
replacing and disposing of the battery.
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 83.
3. Remove the heat sink and fan assembly for easier access to the battery. See “Replacing the heat
sink and fan assembly” on page 105.
4. Locate the battery. See “Locating parts on the system board” on page 72.
5. Remove the old battery.
