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

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 right indicator is solid green. While data is being transmitted, the upper left indicator blinks yellow.

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

Note: If you attach your computer to the ThinkPad Ultrabase Series 3 and use an Ethernet connector, use the Ethernet connector on the ThinkPad Ultrabase Series 3, not the one on the computer.

6

Always On USB connector

The Universal Serial Bus connectors are used for connecting devices compatible with a USB interface, such as a printer or a digital camera.

By default, even if your computer is in sleep (standby) mode, the Always On USB connector still enables you to charge some devices, such as iPod, iPhone, and BlackBerry smartphones, by attaching the devices to the connector.

However, with the ac power adapter attached, if you want to charge these devices when your computer is in hibernation mode or powered off, you will need to open the Power Manager program and configure corresponding settings to enable the Always On USB connector function. For details about how to enable the Always On USB connector function, refer to the on-line help of the Power Manager program.

Note: Your computer is compatible with USB 1.1 and 2.0.

•SD card

•SDHC card
