✎The backup process may take over an hour, depending on the file size and the speed of the computer.
1.Select Start > All Programs > Maintenance > Backup and Restore.
2. Follow the on-screen instructions to set up and create a backup.
✎Windows®includes the User Account Control feature to improve the security of your computer. You may be 
prompted for your permission or password for tasks such as installing software, running utilities, or changing 
Windows settings. Refer to Help and Support for more information.
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.
✎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.
✎If you revert to a restore point and then change your mind, you can reverse the restoration.
Create a system restore point
1. Click Start > Control Panel > System and Security > System.
2. In the left pane, click System Protection.
3. Click the System Protection tab.
4. Under Protection Settings, select the disk for which you want to create a restore point.
5. Click Create.
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. Click Start > Control Panel > System and Security > System.
2. In the left pane, click System protection.
3. Click the System Protection tab.
4. Click System Restore.
5. Follow the on-screen instructions.

Backup and Recovery
Per fo rm in g  a rec over y
✎You can recover only files that you have previously backed up. HP recommends that you use Recovery Manager 
to create an a set of recovery discs (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 
(select models only) on the hard drive. However, computers that include a solid-state drive (SSD) may not have a 
recovery partition. If that is the case, recovery discs have been included with your computer. Use these discs to 
recover your operating system and software.
✎Windows has its own built-in repair features, such as System Restore. If you have not already tried these 
features, try them before using Recovery Manager.
✎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 using 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 using the partition on the hard drive (select models only)
✎Computers with an SSD may not have a recovery partition. If the computer does not have a recovery partition, 
you will not be able to recover using this procedure. Recovery discs have been included for computers that do 
not have a partition. Use these discs to recover your operating system and software.
On some models, you can perform a recovery from the partition on the hard drive, accessed by pressing either the 
Start button or 
f11. This restores the computer to its factory condition.
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 –
a. Turn on or restart the computer, and then press 
esc while the “Press the ESC key for Startup Menu” message 
is displayed at the bottom of the screen. Then press 
f11 while the “Press  for recovery” message is 
displayed on the screen.
2. Click System Recovery in the Recovery Manager window,.
3. Follow the on-screen instructions.
