Charge the computer
Use ac power
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.
Use P-to-P 2.0 charging function
For Intel models, both the USB-C (3.2 Gen 1) connector and Thunderbolt 3 connectors (USB-C) on the
computer feature the Lenovo-unique P-to-P 2.0 charging function.
For AMD models, both USB-C (3.2 Gen 2) connectors on the computer feature the Lenovo-unique P-to-P
2.0 charging function.
When no ac power is available, this feature enables one computer to supply power to another computer
through a USB-C to USB-C cable. When ac power is available for only one computer, this feature enables
both computers to get charged by ac power.
Before using the function, ensure that:
The selected connectors support the P-to-P 2.0 charging function and power delivery function.
