Charge the computer
Use ac power
Notes:
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.
To extend your battery’s lifespan, the battery 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 (Peer to Peer) 2.0 charging function
Both Thunderbolt 4 connectors (USB-C) 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.
To use the function, ensure that Always On USB and Charge in Battery Mode are enabled in UEFI BIOS of
your computers, so that the function works even when the computers are off or in hibernation mode.
1. Restart the computer. When the logo screen is displayed, press F1 to enter the UEFI BIOS menu.
