Audio connector
Connect a headphone or a headset that has a 3.5-mm (0.14-inch) 4-pole plug to the audio connector to
listen to the sound from the computer.
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 the switch, the headset microphone
will be disabled, and the integrated microphones on the computer will be enabled instead.
• The audio connector does not support a conventional microphone. For more information, see “Using
audio features” on page 42.
2 SIM-card tray (on some models)
If your computer has a wireless Wide Area Network (wireless WAN) feature, a Subscriber Identification
Module (SIM) card might be required to establish wireless WAN connections. Depending on the country of
delivery, the SIM card might be already installed in the SIM-card tray. For more information, see “Installing
or replacing the SIM card” on page 73.
3 Media card reader slot
Your computer has a media card reader slot. Insert your flash media card into this slot to read the data
on the card. For more information about the supported cards, see “Using a flash media card or a smart
card” on page 43.
