Replacing The Coin-Cell Battery - Lenovo ThinkCentre M710e User Manual And Hardware Maintenance Manual

Replacing the coin-cell battery

Attention: Do not open your computer or attempt any repairs before reading the Important Product
Information Guide.
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.
To replace the coin-cell battery,
1. Remove the computer cover. See "Removing the computer cover" on page 16.
2. Remove the front bezel. See "Replacing the front bezel" on page 17.
3. Remove the optical drive. See "Replacing the optical drive" on page 18.
4. Remove the storage drive bracket. See "Replacing the storage drive" on page 20.
5. Replace the coin-cell battery.
