DANGER
To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector.
You can only connect an Ethernet cable to this connector.
The Ethernet connector has two indicators that show the status of the network connection. When the
green indicator is on, the computer is connected to a LAN. When the yellow indicator blinks, data is being
transmitted.
Note: If the computer is connected to the ThinkPad OneLink Dock or ThinkPad OneLink Pro Dock, use the
Ethernet connector on the docking station instead of the one on the computer.
4 ac power connector
5 Lenovo OneLink connector
When the ac power adapter is connected to the ac power connector, it provides power to the computer
and charges the battery. When a supported ThinkPad OneLink Dock or ThinkPad OneLink Pro Dock is
connected to the Lenovo OneLink connector, it 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.
Note: Ensure that you keep the connector cover. Reattach it to the Lenovo OneLink connector when
you are not using the Lenovo OneLink connector.
