2 Setting up your computer

WARNING!

To reduce the risk of electrical shock or damage to your equipment:

Place the computer in a location away from water, dust, moisture, and soot. These environmental factors can increase the temperature inside your computer or cause fire or electrocution.

Do not disable the power cord grounding pin. The grounding pin is an important safety feature.

Plug the power cord into an AC outlet that is easily accessible at all times.

Disconnect power from the equipment by unplugging the power cord from the AC outlet. To prevent direct exposure to the laser beam, do not try to open the enclosure of the CD or DVD drive.

The power supply is preset for the country or region in which you purchased your computer. If you move, check the voltage requirements for your new location before plugging the computer into an AC outlet.

To reduce the risk of serious injury read the Safety & Comfort Guide. To access this guide, go to http://www.hp.com/ergo .

Creating recovery media and backups

The following methods of creating recovery media and backups are available on select products only. Choose the available method according to your computer model.

Use HP Recovery Manager to create HP Recovery media after you successfully set up the computer. This step creates a backup of the HP Recovery partition on the computer. The backup can be used to reinstall the original operating system in cases where the hard drive is corrupted or has been replaced. For information on creating recovery media, see

Creating HP Recovery media (select products only) on page 16 . For information on the recovery options that are available using the recovery media, see

Using Windows tools on page 17 .

Use Windows tools to create system restore points and create backups of personal information.

For more information, see

Recovering using HP Recovery Manager on page 18 .

NOTE:

If storage is 32 GB or less, Microsoft System Restore is disabled by default.

Creating HP Recovery media (select products only)

If possible, check for the presence of the Recovery partition and the Windows partition. From the Start menu, select File Explorer, and then select This PC.

If your computer does not list the Windows partition and the Recovery partition, 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 on the HP website. Go to http://www.hp.com/support , select your country or region, and follow the on-screen instructions.

You can use Windows tools to create system restore points and create backups of personal information, see

Using Windows tools on page 17 .

If your computer does list the Recovery partition and the Windows partition, you can use HP Recovery

Manager to create recovery media after you successfully set up the computer. HP Recovery media can be used to perform system recovery if the hard drive becomes corrupted. System recovery reinstalls the original operating system and software programs that were installed at the factory and then configures the factory image if you replace the hard drive.

the settings for the programs. HP Recovery media can also be used to customize the system or restore

Only one set of recovery media can be created. Handle these recovery tools carefully, and keep them in a safe place.

HP Recovery Manager examines the computer and determines the required storage capacity for the media that will be required.

To create recovery discs, your computer must have an optical drive with DVD writer capability, and you must use only high-quality blank DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs. Do not use rewritable discs such as CD±RW, DVD±RW, double-layer DVD±RW, or BD-RE (rewritable Blu-ray) discs; they are not compatible with HP Recovery Manager software. Or, instead, you can use a highquality blank USB flash drive.

If your computer does not include an integrated optical drive with DVD writer capability, but you would like to create DVD recovery media, you can use an external optical drive (purchased separately) to create recovery discs. If you use an external optical drive, it must be connected directly to a USB port on the computer; the drive cannot be connected to a USB port on an external device, such as a USB hub. If you cannot create DVD media yourself, you can obtain recovery discs for your computer from HP. See the Worldwide Telephone Numbers booklet included with the computer. You can also find contact information on the HP website. Go to http://www.hp.com/ support , select your country or region, and follow the on-screen instructions.

Be sure that the computer is connected to AC power before you begin creating the recovery media.

The creation process can take an hour or more. Do not interrupt the creation process.

If necessary, you can exit the program before you have finished creating all of the recovery DVDs.

HP Recovery Manager will finish burning the current DVD. The next time you start HP Recovery

Manager, you will be prompted to continue.

10 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.
