You can attach the AC adapter to the AC adapter connector. The AC adapter converts AC power to the DC power required by the computer.

You can connect the AC adapter with your computer turned either on or off.

The AC adapter works with electrical outlets worldwide. However, power connectors vary among countries. Before using AC power in a foreign

country, you may need to obtain a new power cable designed for use in that country.

Infrared Sensor

The computer’s infrared (IR) sensor lets you transfer files from your computer to another IR-compatible device without using cable connections.

When you receive your computer, the IR sensor is disabled. You can enable the IR sensor using the system setup program.

To transfer files after you enable the IR sensor:

1. Point the computer’s IR sensor directly at the compatible device’s IR sensor. IR devices transmit data in a 30-degree cone of IR light up to a

distanceof1meter(m)(3.3feet[ft]).

2. Start the data communications software on both devices, and then begin to transfer files. Read the documentation that came with your

compatible device to make sure that you operate the device correctly.

Using the IR Sensor

l The default address of the IR port is COM3. If the address causes resource conflicts with other devices, remap the address of the IR sensor.

l When the computer is connected to a Dell docking device, the IR sensor on the computer is automatically disabled.
