Coin-cell battery

Prerequisite

Before you start, read Generic Safety and Compliance Notices, and print the following instructions.

Your computer has a special type of memory that maintains the date, time, and settings for built-in features,

such as parallel connector assignments (configurations). A coin-cell battery keeps this information active

when you turn off the computer.

The coin-cell battery normally requires no charging or maintenance throughout its life; however, no coin-cell

battery lasts forever. If the coin-cell battery fails, the date and time information is lost. An error message is

displayed when you turn on the computer.

To dispose of the coin-cell battery, refer to the "Lithium coin-cell battery notice" in the Safety and Warranty

Guide.

For access, remove the following parts in order, if any:

• "Computer cover" on page 22.

• "Internal speaker" on page 25.

• "System fan" on page 26.

Removal steps

Note: After installing a new coin-cell battery, reset the system date and time in the UEFI BIOS menu.
