Recovering the computer settings

Performing backup and recovery operations using the OneKey Recovery Pro program
The OneKey Recovery Pro program enables you to back up all your hard disk drive contents including the
operating system, data files, software programs, and personal settings. You can designate where the
OneKey Recovery Pro program stores the backup. After you have backed up the contents on the hard disk
drive, you can restore the complete contents of the hard disk drive, restore only the selected files, or restore
only the Windows operating system and applications.
Restoring factory contents using the Product Recovery program
On the Windows 7 operating system, you can use recovery media to restore the computer settings to the
factory contents only.
Attention: When you use the Product Recovery program to restore the computer settings, all the data you
have stored on the hard disk drive will be deleted and the computer settings will be restored to the factory
contents. During the restoring process, you will be given the option to save one or more files currently on the
hard disk drive to other media before the data is deleted.

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.

Supervisor password

A supervisor password (SVP) protects the system information stored in the BIOS. The user must enter the
SVP in order to get access to the BIOS and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the service technician, there is no
service procedure to reset the password. The system board must be replaced for a scheduled fee.
