following situations:
• When your computer is on or in sleep mode
• When your computer is off or in hibernation mode, but connected to ac power
Attention: When you attach a USB cable to this connector, ensure that the USB mark is facing upward.
Otherwise the connector might get damaged.
To charge these devices when the computer is off or in hibernation mode, and the computer is not connected
to ac power, do the following:
1. Start the Lenovo Settings program. See "Accessing Lenovo programs" on page 11.
2. Click POWER.
3. Follow the instructions on the screen to make your preferred setting.
3 Ethernet connector

DANGER
To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector.

The Ethernet connector has two indicators that show the status of the network connection. When the green
indicator is on, it indicates that the computer is connected to a LAN and a session with the network is
available. When the indicator blinks yellow, data is being transmitted.
