When the ac power adapter is connected to the ac power connector, the ac power adapter provides ac power to the computer and charges the battery. When a supported ThinkPad OneLink Dock option is connected to the Lenovo OneLink connector, the option can not only extend the computer capabilities but also provide ac power to the computer and charge the battery.

To use the Lenovo OneLink connector, you need to remove the connector cover from the Lenovo OneLink connector first.
