Charge the battery

When the battery power is low, charge your battery by connecting your computer to ac power.

The battery is fully charged in about four to eight hours. If the power adapter shipped with your computer

supports

the rapid charge function, the battery is 80% charged in about one hour when the computer is

turned

off. The actual charging time depends on the battery size, the physical environment, and whether you

are

using the computer.

Battery charging is also affected by the battery temperature. The recommended battery temperature range

for

charging the battery is between 10°C (50°F) and 35°C (95°F).

Notes:

• To maximize the life of the battery, once the battery is fully charged, it must discharge to below 95%

before it will be allowed to recharge again.

• To extend your battery’s lifespan, we may optimize its full charge capacity based on your usage. After

prolonged periods of limited use, full battery capacity may not be available until you discharge to as low

as 20% and recharge completely. For more information, refer to the power section of Lenovo Vantage.

Maximize the battery life

• Lower the brightness of the computer display.
