4 Combo audio jack<br />

To listen to the sound from your computer, connect a headphone or a headset, that has a 3.5mm 4-pole<br />

plug, to the combo audio jack.<br />

Notes:<br />

• If you are using a headset with a function switch, for example, a headset for an iPhone mobile digital<br />

device, do not press this switch while using the headset. If you press it, the headset microphone will<br />

be disabled, and the internal microphone will be enabled instead.<br />

• The combo audio jack does not support a conventional microphone. For more information about the audio<br />

devices supported by the combo audio jack of your computer, see “Using audio features” on page 77.<br />

5 Ethernet connector<br />

Connect your computer to a LAN with the Ethernet connector.<br />

DANGER<br />

To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector.<br />

You can only connect an Ethernet cable to this connector.<br />

Two indicators, to the upper right and left of the connector, show the status of the network connection.<br />

When your computer connects to a LAN and a session with the network is available, the upper right indicator<br />

is solid green. While data is being transmitted, the upper left indicator blinks yellow.<br />

For details, refer to the instructions in “Access Connections” on page 34.<br />

Note: If you attach your computer to the ThinkPad Ultrabase Series 3 and use an Ethernet connector, use<br />

the Ethernet connector on the ThinkPad Ultrabase Series 3, not the one on the computer.<br />

6 Always On USB connector<br />

The Universal Serial Bus connectors are used for connecting devices compatible with a USB interface,<br />

such as a printer or a digital camera.<br />

By default, even if your computer is in sleep (standby) mode, the Always On USB connector still enables<br />

you to charge some devices, such as iPod, iPhone, and BlackBerry smartphones, by attaching the devices<br />

to the connector.<br />

However, with the ac power adapter attached, if you want to charge these devices when your computer<br />

is in hibernation mode or powered off, you will need to open the Power Manager program and configure<br />

corresponding settings to enable the Always On USB connector function. For details about how to enable<br />

the Always On USB connector function, refer to the on-line help of the Power Manager program.<br />

Note: Your computer is compatible with USB 1.1 and 2.0.<br />

7 Media card reader slot<br />

Depending on the model, your computer may have a media card reader slot. The media card reader<br />

supports the following cards:<br />

• SD card<br />

• SDHC card<br />

• SDXC card<br />

• MultiMediaCard<br />
