USB-C connectors (Thunderbolt 3 compatible) / power connectors
The USB-C connectors on your computer support both the USB Type-C™ standard and the Thunderbolt 3
technology. With an appropriate USB-C cable connected, you can use the connectors to transfer data,
charge your device, or connect your computer to external displays.
The two USB-C connectors also work as power connectors. The ac power adapter shipped with your
computer is a USB-C power adapter. Use the shipped power adapter and power cord to connect the
computer to ac power through either of the two USB-C connectors.
Lenovo provides various USB-C accessories to help you expand your computer functionality. For more

Note: When the battery power is below 10%, the USB-C accessories connected to the USB-C connectors
might not work correctly.

connections" on page 24.
