4 Always On USB 3.1 connector Gen 1
By default, the Always On USB 3.1 connector Gen 1 enables you to charge the USB-compatible devices in
the 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.

connected to ac power, do the following:
1. Start the Lenovo Companion program. See “Accessing Lenovo programs” on page 16.
2. Click Hardware Settings ➙ Always On USB.

5 High-Definition Multimedia Interface (HDMI) connector
The HDMI connector is a digital audio and video interface. It enables you to connect your computer to a
compatible digital audio device or video monitor, such as an HDTV.
6 Nano-SIM-card tray
If your computer supports the wireless wide area network (wireless WAN) feature, a nano Subscriber Identity
Module (SIM) card might be required to establish wireless-WAN connections. Depending on the country or
region of delivery, the nano-SIM card might be already installed in the nano-SIM-card tray. For more
information, see “Using the wireless-WAN connection” on page 33.
7 MicroSD card slot
You can insert a microSD card into the microSD card slot for data access or storage. For more information,
see “Using a media card or a smart card” on page 37.
8 Ethernet connector
The Ethernet connector enables you to connect the computer to a local area network (LAN).
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 network status indicators. 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 a docking station, use the Ethernet connector on the docking station
instead of the one on the computer.
9 Smart-card slot (available on some models)
You can use smart cards for authentication, data storage, and application processing. Within large
organizations, you might also use smart cards for strong security authentication of single sign-on (SSO). For
more information, see “Using a media card or a smart card” on page 37.
