							Backing up
Backup tips
●Connect the computer to AC power during the backup process.
●Store personal files in the Documents folder and back them up regularly.
●Back up templates that are stored in their associated programs.
●Save customized settings that appear in a window, toolbar, or menu bar by taking a screen shot
of your settings. The screen shot can be a time-saver if you have to reset your preferences.
To create a screen shot:
1.Display the screen you want to save.
2.Copy the screen image:
To copy only the active window, press alt+fn+prt sc.
To copy the entire screen, press fn+prt sc.
3.Open a word-processing document, and then select Edit > Paste.
The screen image is added to the document.
4.Save the document.
Backing up your information
Recovery after a system failure is as complete as your most current backup. You should create your
initial backup immediately after software setup. As you add new software and data files, you should
continue to back up your system on a regular basis to maintain a reasonably current backup.
To create a backup using Backup and Restore Center, follow these steps:
1.Select Start > All Programs > Maintenance > Backup and Restore Center.
2.Follow the on-screen instructions to back up your entire computer (select models only) or your files.
NOTE: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.

							Performing a recovery
In case of system failure, use the f11 recovery tool to recover your original hard drive image. The image
includes the Windows operating system and software programs installed at the factory.
NOTE:Windows Vista provides additional recovery tools through the operating system. For additional
information, go to Help and Support.
NOTE:If you are unable to boot (start up) your computer, you must purchase a Windows Vista
operating system DVD to reboot the computer and repair the operating system. For additional
information, refer to the “Recovering information using a Windows Vista operating system DVD
(purchased separately)” section in this guide.
Recovering the hard drive using f11
CAUTION:Using f11 completely erases hard drive contents and reformats the hard drive. All files you
have created and any software installed on the computer are permanently removed. The f11 recovery
tool reinstalls the original operating system and HP programs and drivers that were installed at the
factory. Software not installed at the factory must be manually reinstalled. Personal files must be restored
from a backup.
To recover the original hard drive image, follow these steps:
1.If possible, back up all personal files.
2.If possible, check for the presence of the HP Recovery partition. To find the partition, select Start
> Computer.
NOTE:If the HP Recovery partition has been deleted, you will need to recover your operating
system and programs using the Windows Vista operating system DVD and the Driver Recovery
disc (purchased separately). For additional information, refer to the “Recovering information using
a Windows Vista operating system DVD (purchased separately)” section in this guide.
3.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.
4.Press f11 while the “Press for recovery” message is displayed on the screen.
5.Follow the on-screen instructions.

							Recovering information using a Windows Vista operating
system DVD (purchased separately)
If you are unable to boot (start up) your computer, you must purchase a Windows Vista operating system
DVD to reboot the computer and repair the operating system. Make sure that your most recent backup
(stored on discs or on an external drive) is easily accessible. To order a Windows Vista operating system
DVD, go to

be permanently removed. When reformatting is complete, the recovery process will help you restore the
operating system, as well as drivers, software, and utilities.
