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 of the 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 make it subject 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 “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.

the computer?
1. Carefully unplug the ac power adapter and turn off the computer immediately.
The more quickly you stop the current from passing through the computer the
more likely you will reduce damage from short circuits.
Attention: Although you might lose some data or work by turning off the
computer immediately, leaving the computer on might make your computer
unusable.
2. Wait until you are certain that all the liquid is dry before turning on your
computer.
CAUTION:
Do not try to drain out the liquid by turning over the computer. If your
computer has keyboard drainage holes on the bottom, the liquid will be
drained out through the holes.
