Chapter 1. Getting to know your computer

■ Connecting USB devices

You can connect a USB device to your computer by inserting its USB plug (Type A) into the USB port on your computer.

Illustration of a hand inserting a USB into a network device labeled with HDMI port (no text or symbols beyond labels)

The first time you plug a USB device into a particular USB port on your computer, Windows automatically installs a driver for that device. After the driver is installed, you can disconnect and reconnect the device without performing any additional steps.

Note: Typically, Windows detects a new device after connecting it, and then installs the driver automatically. However, some devices may require you to install the driver before connecting. Check the documentation provided by the device's manufacturer before connecting the device.

Before disconnecting a USB storage device, make sure your computer has finished transferring data by that device. Click the Safely Remove Hardware and Eject Media icon in the notification area of the Windows desktop screen to remove the device before disconnecting.

Notes:

- If your USB device uses a power cord, connect the device to a power source before connecting it. Otherwise, the device may not be recognized.

- When in sleep mode, you can only use keyboard instead of mouse to wake up the computer.

■ Connecting a Bluetooth device

If your computer has an integrated Bluetooth adapter card, it can connect to and transfer data wirelessly to/from other Bluetooth enabled devices, such as notebook computers, PDAs and cell phones. You can transfer data between these devices up to 10 meters range in open space.

Note: The actual maximum range may vary due to interference and transmission barriers. For best transfer speed, place the device as near your computer as possible.

Enabling Bluetooth and WLAN communications on your computer

Press to make configuration.

Notes:

• When you do not need to use the Bluetooth function, turn it off to save battery power.
• You need to pair the Bluetooth enabled device with your computer before you can transfer data between them. Read the documentation supplied with the Bluetooth enabled device for details on how to pair the device with your computer.
