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 (configuration). 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 battery
lasts forever. If the coin-cell battery fails, the date and time information is lost.
Refer to the “Lithium coin cell battery notice” in the Safety, Warranty, and Setup Guide for information about
replacing and disposing of the battery.
