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.

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.

Before disconnecting a USB storage device, make sure your computer has

finished transferring data by that device. Make sure you properly eject the

device from the Windows operating system, to avoid data corruption.

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.

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.

Chapter 1. Getting to know your 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.

Enabling Blue tooth and WLAN communications on your computer

Press Fn + F5 to make configuration.

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.

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.
