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.
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.
