Charging the Battery
When you check the battery status and find that the percentage of power
remaining is low or when the power alarm alerts you that remaining power
is low, you need to charge your battery or replace it with a charged battery.
If an AC outlet is convenient, first, connect the power cord to the
transformer pack; second, plug the power cord into an electrical outlet; and
then connect the AC adapter to the power jack of the computer.
The charging time is affected by the physical environment. The battery
status indicator lets you know that the battery is charging, and also notifies
you when the battery is fully charged.
Note: To increase the life of the battery, the computer does not start
recharging the battery if the remaining power is greater than
95 percent.
Handling the Battery
Danger: Do not attempt to disassemble or modify the battery pack.
Attempting to do so can cause an explosion, or liquid leakage from the
battery pack.
A battery pack other than the one specified by Lenovo, or a disassembled or
modified battery pack is not covered by the warranty.
Danger: If the rechargeable battery pack is incorrectly replaced, there is
danger of an explosion. The battery pack contains a small amount
of harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.
• Keep it away from children.
Danger: Do not put the battery pack in trash that is disposed of in landfills.
When disposing of the battery, comply with local ordinances or
regulations and your company’s safety standards.
Danger: There is a danger of an explosion if the backup battery is
incorrectly stored. The lithium battery contains lithium and can
explode if it is not properly handled, or disposed of. Replace only
with a battery of the same type. To avoid possible injury or death,
Do not: (1) throw or immerse into water, (2) allow it to heat to
more than 100 degrees C (212 degrees F), or (3) attempt to repair
or disassemble it. Dispose of it as required by local ordinances or
regulations and your company’s safety standards.
