Chapter 2. Using Your Computer
Before you charge the battery, make sure that its temperature is at least
10°C (50°F).
Charging the battery
When you check the battery status and find that the battery is low, you
need to charge the 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 the electrical outlet,
and then connect the AC adapter to the power jack of the computer.
Charging time will depend on the usage environment.
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.
