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 Safety and Warranty Guide for information about replacing and disposing of the battery.

To change the battery:

1.Turn off the computer and disconnect the power cord from the electrical outlet and from the computer.

2.Remove the computer cover. See “Removing the cover” on page 9.

3.You might have to access the system board components. See “Accessing system board components and drives” on page 10.

4.Locate the battery. See Figure 3 on page 7.

5.Remove the old battery.

6.Install the new battery.

7.Replace the computer cover, and connect the cables. See Chapter 4, “Completing the parts replacement,” on page 33.

Note: When the computer is turned on for the first time after battery replacement, an error message might be displayed. This is normal after replacing the battery.

8.Turn on the computer and all attached devices.

9.Use the Setup Utility program to set the date and time and any passwords. See "Using the Setup Utility" in the User Guide.
