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 has been 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 to that device. Click the Safely Remove Hardware
and Eject Media icon in the Windows notification area to remove the device
before disconnecting.
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.
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. Recovery system
Lenovo provides Lenovo OneKey Recovery system or Push-button reset for
system recovery, which depends on the pre-installed software. Refer to the
actual product. You can perform either to start the system recovery.
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.
Backing up the system partition
You can back up the system partition to an image file. This image file can be
used to restore the system partition. To back up the system partition:
1In Windows, press the Novo button or double-click OneKey Recovery
icon to start the Lenovo OneKey Recovery system.
2Click System Backup.
3Select a back-up location and click Next to start the backup.
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.
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.

Push-button reset - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Push-button reset is a built-in recovery tool that enables users to restore
their operating system to its original state. This preserves their data and
important customizations, without the need to back up their data in advance.
The following Push-button reset features are available to users from
multiple locations within Windows:
Refreshing the computer
Fixes software problems by reinstalling the factory default configuration.
This preserves the user’s data, important settings, and any Windows Store
apps previously purchased from the Windows Store.
Resetting the computer
Prepares the computer for recycling or transfer of ownership. This reinstalls
the factory default configuration and returns all user data and applications to
the state of their original Out-of-Box Experience (OOBE).
Using Push-button reset
Push-button reset can be launched using one of the following methods:
• Novo button:
- Shut down the computer and wait at least five seconds. Press the Novo
button and then select System Recovery.
• Settings:
-Settings → Update & security → Recovery → Advanced startup → select
Restart now.
For more instructions, see the Windows Help and Support file on your
computer.
When I purchased my computer, it included a copy of Windows. How can I
determine whether the copy of Windows is preinstalled by Lenovo?
On the outside of the sales package of your computer, you should find a
label containing configuration information for your computer. Check the
printed string next to OS. If it contains Windows or WIN, the copy of
Windows was preinstalled by Lenovo.
Chapter 3. Recovery system
24
What is the Recovery Partition?
If your computer is preinstalled with any version of Windows 10, the
storage device of your computer contains a Recovery Partition. This
partition contains the image file of the preinstalled Windows operating
system. In cases of system failure, you can use the Lenovo OneKey
Recovery system or the Windows Reset feature to restore the operating
system to its factory status.
I uninstalled a preinstalled software, but there is no significant increase in the
free drive space.
The copy of Windows running on your computer may be Compact
technology enabled. For computers with Compact technology enabled
Windows, the majority of files needed for preinstalled software are
installed on the Recovery Partition and won’t be deleted through normal
uninstallation.
What happens if I attempt to delete or modify the Recovery Partition?
Attention: Do not delete or modify the Recovery Partition on a Compact
technology enabled computer.
If the Recovery Partition is deleted or modified, you may not be able to
restore Windows to the factory status. For computer models on which
Compact technology is enabled, deleting the Recovery Partition may cause
Windows to fail to start.
How can I determine whether the Windows running on my computer is
Compact technology enabled?
Compact technology is normally enabled on copies of Windows 10 Update
running on SSD (or eMMC) -only computer models. To check your
computer,
1Right-click the Start button in the lower-left corner and select Disk
Management.
2The Disk Management program starts.
Note: The Recovery Partition is not assigned a drive letter and cannot be accessed through
Windows File Explorer.
Chapter 3. Recovery system
25
If Wim Boot is labeled on the Windows partition (as illustrated), Compact
technology is enabled on your copy of Windows.
Where can I find drivers for the various hardware devices of my computer?
If your computer is preinstalled with a Windows operating system, first
check the installation program on the D partition of your hard disk (for
select models, on the C partition). If you cannot find the drivers for all the
hardware devices that you need there, download the drivers from the
Lenovo consumer support website.
Note: The Lenovo support Web site contains the latest drivers.

What can I do if the back-up process fails?
If you can start the backup but it fails during the back-up process, try the
following steps:
1Close all open programs, and then restart the back-up process.
2Check to see if the destination media is damaged. Select another path

When do I need to restore the system to its factory status?
Use this feature when the operating system fails to start up. If there is
critical data on the system partition, back it up before starting recovery.
BIOS setup utility
What is the BIOS setup utility?
The BIOS setup utility is ROM-based software. It displays basic computer
information and provides options for setting boot devices, security,
hardware mode, and other preferences.
How can I start the BIOS setup utility?

mode, start the BIOS setup utility and set boot mode to UEFI or Legacy
Support on the boot menu.
When do I need to change the boot mode?
The default boot mode for your computer is UEFI mode. If you need to
install a legacy operating system, such as Windows, Linux or Dos, etc (that
is, any operating system before Windows 8) on your computer, you must
change the boot mode to Legacy Support. The legacy operating system,
such as Windows, Linux or Dos, etc cannot be installed if you don't change
the boot mode.
