1 Monitor connector
The monitor connector is used to connect an external monitor or projector to your computer.
For details, refer to the instructions in "Attaching an external monitor" on page 39.
2 Fan louvers (left)
The internal fan and louvers enable air to circulate in the computer and cool the central processor.
Note: To avoid impeding airflow, do not place any obstacle in front of the fan.
3 HDMI port
Your computer supports the high-definition multimedia interface (HDMI) port, a digital audio and video
interface that can connect a compatible digital audio device or video monitor such as an HDTV.
4 USB connector
The USB connector is used for connecting USB interface-compatible devices, such as a printer or digital
camera.

Ethernet connector
The Ethernet connector is used to connect your computer to a LAN.
An indicator to the left of the connector shows the status of ac power. When the ac power adapter is
connected, the indicator is on. If a battery is installed in the computer, the indicator is green when the
battery charges.
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.
6 Combo audio jack
To listen to the sound from your computer, connect a headphone or a headset that has a 3.5mm 4-pole
plug to the combo audio jack.
Notes:
• If you are using a headset with a function switch, for example, a headset for an iPhone mobile digital
device, do not press this switch while using the headset. If you press it, the headset microphone will
be disabled, and the internal microphone will be enabled instead.
• The combo audio jack does not support a conventional microphone. For more information about the
