HP Pavilion Dv6800 Special Edition Entertainment Notebook Pc Series Service Guide

							Using system restore points
When you back up your system, you are creating a system restore point. A system restore point allows
you to save and name a snapshot of your hard drive at a specific point in time. You can then recover
back to that point if you want to reverse subsequent changes made to your system. 
NOTE:Recovering to an earlier restore point does not affect data files saved or e-mails created since
the last restore point.
You also can create additional restore points to provide increased protection for your system files and
settings.
When to create restore points
●Before you add or extensively modify software or hardware
●Periodically, whenever the system is performing optimally
NOTE:If you revert to a restore point and then change your mind, you can reverse the restoration.
Create a system restore point
1.Select Start > Control Panel > System and Maintenance > System.
2.In the left pane, click System protection.
3.Click the System Protection tab.
4.Under Automatic restore points, select the disk for which you want to create a restore point.
5.Click Create.
The System Protection window opens.
6.Follow the on-screen instructions.
Restore to a previous date and time
To revert to a restore point (created at a previous date and time), when the computer was functioning
optimally, follow these steps:
1.Select Start > Control Panel > System and Maintenance > System.
2.In the left pane, click System protection.
3.Click the System Protection tab.

							Performing a recovery
NOTE:You can only recover files that you have previously backed up. HP recommends that you use
Recovery Manager to create an entire drive backup as soon as you set up your computer.
Recovery Manager software allows you to repair or restore the system if you experience system failure or
instability. Recovery Manager works from recovery discs that you create or from a dedicated recovery
partition on the hard drive. 
NOTE:Windows has its own built-in repair features, such as System Restore and driver roll-back
capabilities. If you have not already tried these features, try them before using Recovery Manager.
NOTE:Recovery Manager recovers only software that was preinstalled at the factory. Software not
provided with this computer must be downloaded from the manufacturers Web site or reinstalled from
the disc provided by the manufacturer.
Recovering from the recovery discs
To restore the system from the recovery discs:
1.Back up all personal files.
2.Insert the first recovery disc into the optical drive and restart the computer.
3.Follow the on-screen instructions.
Recovering from the partition on the hard drive
You can perform a recovery from the partition on the hard drive from either the Start button or f11.
To restore the system from the partition, follow these steps:
1.Access Recovery Manager in either of the following ways:
●
Select Start > All Programs > Recovery Manager > Recovery Manager.
–or–
●Restart the computer and press f11 while the “Press  for recovery” message is displayed
on the screen. Then select Recovery Manager.
Recovery Manager opens.
2.Click Advanced Options.
3.Click System recovery, and then click Next.
4.Follow the on-screen instructions.
