Lenovo recovery system
Where are the recovery discs?
Your computer did not come with recovery discs. Use the Lenovo recovery
system if you need to restore the system to its factory status or to a
previously generated backup.
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:
1 Close all open programs, and then restart the back-up process.
2 Check to see if the destination media is damaged. Select another path
and then try again.
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.
