Use the P-to-P 2.0 charging function
The USB-C connector on the computer features 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.

• The selected connectors support the P-to-P 2.0 charging function and power delivery function.
• Always On USB and Charge in Battery Mode are enabled in UEFI BIOS of both computers, so that the
function works even when the computers are off or in hibernation mode. To enable Always On USB and
Charge in Battery Mode:
1. Enter the UEFI BIOS menu. See "Enter the UEFI BIOS menu" on page 29.
2. Click Config ➙ USB to enable Always On USB and Charge in Battery Mode.
Step 1.
Enter the UEFI BIOS menu. See "Enter the UEFI BIOS menu" on page 29.
Step 2.

Note: The actual charging speed using the Lenovo-unique P-to-P 2.0 charging function varies
depending on many factors, such as the remaining battery power of the computers, the wattage of
the ac power adapter, and whether you are using the computers.
