Fan louver
The fan louvers and the internal fan enable air to circulate in the computer to ensure proper cooling,
especially the cooling of the microprocessor.
Note: To ensure proper airflow, do not place any obstacles in front of the fan louvers.

USB 3.0 connectors
The Universal Serial Bus (USB) 3.0 connectors are used for connecting devices compatible with a USB
interface, such as a USB printer or a digital camera.
Note: When you attach a USB cable to the connector, make sure that the USB mark is facing upward.
Otherwise the connector might be damaged.

Ethernet connector
Connect your computer to a LAN with the Ethernet connector.
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.
Two indicators, to the upper right and left of the connector, show the status of the network connection.
When your computer connects to a LAN and a session with the network is available, the upper left indicator
is steady green. While data is being transmitted, the upper right indicator blinks yellow.

Combo audio connector
To listen to the sound from your computer, connect a headphone or a headset that has a 3.5 mm 4-pole plug
to the combo audio connector.
Notes:
• If you are using a headset with a function switch, do not press this switch while using the headset. If
you press the switch, the headset microphone will be disabled, and the integrated microphones on
the computer will be enabled instead.
• The combo audio connector does not support a conventional microphone. For more information, see
