Coin-cell battery
Attention: Do not open your computer or attempt any repair before reading and understanding the “Read
this first: Important safety information” on page iii.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features.
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, 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 coin-cell battery.
To replace the coin-cell battery, do the following:
1. Prepare your computer. See “Preparing your computer and removing the computer cover” on page 57.
2. Locate the coin-cell battery. See “Parts on the system board” on page 6.
3. Remove the old coin-cell battery.
