Coin-cell battery
Attention: Do not open your computer or attempt any repair before reading and understanding the Chapter
1 “Read this first: Important safety information” on page 1.
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, time, and configuration information (including passwords)
are lost. An error message is displayed when you turn on the computer.
