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.
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. Make sure you properly eject the device from the Windows operating system, to avoid data corruption.
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.
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 F7 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.

system is not available.
To utilize the features of the OneKey Recovery system, your hard disk already includes a
hidden partition by default to store the system image file and the OneKey Recovery system program files. This default partition is hidden for security reasons, which explains why the available disk space is less than the stated capacity.

1
Press the Novo button to start the Lenovo OneKey Recovery system.
2
Click System Backup.

Notes:
You can choose a back-up location on the local hard disk drive or an external storage
device.
Remove the removable hard disk drive before starting the Lenovo OneKey Recovery
system. Otherwise, data from the removable hard disk drive might be lost.
The back-up process may take a while.
The back-up process is only available when Windows can be started normally.
Restoring
You can choose to restore the system partition to its original status or to a previously created back-up point. To restore the system partition:
1
Press the Novo button to start the Lenovo OneKey Recovery system.
