Restoring the factory contents by using OneKey Recovery
Restore of factory default
The Lenovo computers come with pre-installed OneKey Rescue System. In order to save application files
and the initial backup files of the system, the hard disk in a Lenovo computer includes a hidden partition
when it is shipped. If you need to restore the system to the point of your first boot up, just enter Lenovo
OneKey Rescue System and run Restore to factory default. For more information, refer to the help
information system about the program.
Note: This will delete all the new data on the system partition (C drive), which is not recoverable. Be sure to
back up your critical data before you perform this action.
Using recovery discs
When you replace a hard disk drive in your computer, you are unable to use the preinstalled Lenovo OneKey
Recovery and OneKey Rescue. However, you can use the recovery discs that store your backup data to
restore your new hard drive to a previous backup status.
Note: You can create recovery discs by burning the backup image to a CD/DVD as recovery discs. For more
information, refer to the help information system about the program.
When you use the recovery discs to boot your computer, the system will enter the user interface of system
recovery automatically. You will be prompted to insert the backup discs to complete the whole recovery
process.
Note: The recovery process might take up to 2 hours.
Passwords
As many as two passwords might be needed for a Lenovo notebook computer: the power-on password, the
hard disk password, and the supervisor password.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.
Power-on password
A power-on password (POP) protects the system from being powered on by an unauthorized person. The
password must be entered before an operating system can be booted.
