							●To use the Factory Reset option (select models only), you must use HP Recovery media. If you
have not already created recovery media, see 
Creating HP Recovery media (select models only)
on page 48.
●If your computer does not allow the creation of HP Recovery media or if the HP Recovery media
does not work, you can obtain recovery media for your system from support. See the 
Worldwide
Telephone Numbers
 booklet included with the computer. You can also find contact information
from the HP website. Go to 
http://www.hp.com/support, select your country or region, and follow
the on-screen instructions.

data. Before beginning recovery, back up any personal data you want to retain.
Using HP Recovery media, you can choose from one of the following recovery options:
NOTE:Only the options available for your computer display when you start the recovery process.
●System Recovery—Reinstalls the original operating system, and then configures the settings for
the programs that were installed at the factory.
●Minimized Image Recovery (select models only)—Reinstalls the operating system and all
hardware-related drivers and software, but not other software applications.
●Factory Reset—Restores the computer to its original factory state by deleting all information
from the hard drive and re-creating the partitions. Then it reinstalls the operating system and the
software that was installed at the factory.
The HP Recovery partition (select models only) allows System Recovery and Minimized Image
Recovery (select models only).
Using the HP Recovery partition (select models only)

							13 Electrostatic Discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:
●If removal or installation instructions direct you to unplug the computer, first be sure that it is
properly grounded.
●Keep components in their electrostatic-safe containers until you are ready to install them.
●Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●Use nonmagnetic tools.
●Before handling components, discharge static electricity by touching an unpainted metal surface.
●If you remove a component, place it in an electrostatic-safe container.
