Rechargeable battery pack
Your computer includes a built-in, rechargeable battery pack that makes mobile computing a reality. When
the computer is plugged into an electrical outlet, the battery charges. If you use the computer when you
don't have access to an electrical outlet, the battery discharges to supply electricity that the computer
system requires for operation.
You can charge the battery any time you want. The battery packs of Lenovo computers support multiple
charging modes that are suitable for different power usage habits. You can switch the battery’s active
charging mode in Lenovo Vantage or Lenovo PC Manager.
Battery charging is also affected by its temperature. The recommended temperature range for charging the
battery is between 10°C (50°F) and 35°C (95°F).
Note:
You can check the battery temperature in Lenovo Vantage.
To maximize the life of the battery, once the battery is fully charged, it must discharge to 94% or lower
before it will be allowed to recharge again.
Normal mode
Normal mode is the most basic charging mode. In normal mode, it typically takes 2 to 4 hours for the battery
to charge from 0% to 100%.
