Coin-cell battery

Prerequisite
Before you start, read Generic Safety and Compliance Notices, and print the following instructions.
DANGER
If the coin-cell battery is incorrectly replaced, there is danger of an explosion. The coin-cell battery
contains a small amount of harmful substance. To avoid possible injury:
• Replace only with a battery type recommended by Lenovo.
• Keep the battery away from fire.
• Do not expose it to excessive heat.
• Do not expose it to water or rain.
• Do not short-circuit it.
• Do not drop, crush, puncture the battery, or subject it to strong forces. Battery abuse or
mishandling can cause the battery to overheat, which can cause gasses or flame to "vent" from
the battery or coin-cell battery.
Note: To dispose of the coin-cell battery, refer to the "Lithium coin-cell battery notice" in the Safety and
Warranty 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 and time information is lost. An error message is
displayed when you turn on the computer.
Replacement procedure
1. Remove the power cord. See "Power cord" on page 24.
2. Remove the left side cover. See "Left side cover and right side cover" on page 24.
3. Disengage the latch to eject the battery.
