Connecting USB device
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 has been installed, you can
disconnect and reconnect the device without performing any additional steps.
Note: Typically, Windows detects a new device after it has been connected, 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 to that device. Click the Safely Remove Hardware and Eject Media icon in the Windows
notification area to remove the device before disconnecting.
Note: 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.

Chapter 3. Lenovo OneKey Recovery System
The Lenovo OneKey Recovery System is software designed to back up and restore your
computer. You can use it to restore the system partition to its original status in case of a system
failure. You can also create user backups for easy restoration as required.
Notes:
•If your computer is preinstalled with a GNU/Linux operating system, OneKey Recovery 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.

•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:
1In Windows, press the Novo button or double-click OneKey Recovery icon to start the
Lenovo OneKey Recovery System.
2Click System Recovery. The computer will restart to the recovery environment.

partition before starting the recovery process.
•The recovery process may take a while. So be sure to connect the AC power adapter to your computer
during the recovery process.
•The above instructions should be followed when Windows can be started normally.
