HP Pavilion dm4 User Manual

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 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.
Performing a recovery
NOTE: You can recover only files that you have previously backed up. HP recommends that you
use HP Recovery Manager to create 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 or from a dedicated recovery
partition (select models only) on the hard drive. However, if your computer includes a solid-state drive
(SSD), you 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.
NOTE: 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.
NOTE: Recovery Manager recovers only software that was preinstalled at the factory. Software not
provided with this computer must be downloaded from the manufacturer's 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 dedicated recovery partition (select models only)
NOTE: 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.
