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,
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, time, and configuration information (including
passwords) are lost. An error message is displayed when you turn on the computer.
1. Remove the computer cover. For details, see "Computer cover" on page 57.
2. Remove the internal speaker if necessary. For details, see "Internal speaker" on page 62.
