Replacing the coin-cell battery
Attention: Do not open your computer or attempt any repair before reading and understanding the Chapter
1 "Read this first: Important safety information" on page 1.
This section provides instructions on how to replace the coin-cell 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 coin-cell battery keeps the information active when you
turn off the computer.
The coin-cell battery normally requires no charging or maintenance throughout its life. However, if the
coin-cell 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 the "Lithium coin cell battery notice" in the Safety, Warranty, and Setup Guide for information about
replacing and disposing of the coin-cell battery.
To replace the coin-cell 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 frame stand. See "Removing and installing the frame stand" on page 99.
4. Remove the computer cover. See "Removing the computer cover" on page 102.
