Maximize The Battery Life; Set Power Button Behaviors - Lenovo ThinkPad X1 Yoga Gen 5 User Manual

• 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 45.
2. Click Config ➙ USB to enable Always On USB and Charge in Battery Mode.
To use the function:
• When no ac power is available:
The remaining battery power of computer A should be at least 30% and be 3% higher than that of
computer B. To check the battery status, see "Check the battery status" on page 29. Connect the
computers to each other with a USB-C to USB-C cable. In this situation, computer A works as the power
supply. Once the remaining battery power of computer A is lower than 30%, computer A stops supplying
power to computer B.
• When ac power is available:
Connect the computers to each other with a USB-C to USB-C cable. Connect one computer to ac power.
In this situation, ac power works as the power supply and both computers get charged.
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.
