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

This section provides instructions on how to replace 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 the information active when you turn
off the computer.
The battery normally requires no charging or maintenance throughout its life. However, if the battery fails,
the date, time, and configuration information (including passwords) are lost. An error message will be
displayed when you turn on the computer.
Refer to “Lithium 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. Place a soft, clean towel or cloth on the desk or other flat surface. Hold the sides of your computer and
gently lay it down so that the screen is against the surface and the cover is facing up.
3. Remove the computer cover. See “Removing the computer cover” on page 71.
4. Remove the VESA mount bracket. See “Removing and reinstalling the VESA mount bracket” on page 71.
5. Locate the battery on the system board. See “Locating major FRUs and CRUs” on page 63.
6. Remove the system board shield to get access to the battery. See “Removing and reinstalling the
