Replacing The Coin-Cell Battery - Lenovo THINKCENTRE M710q User Manual And Hardware Maintenance Manual

Replacing the coin-cell battery

Attention
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.
