A sudden discharge of static electricity from your or other conductor can destroy static-sensitive devices nger

or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to

electrostatic discharge (ESD) may not appear to be at all and can work perfectly throughout a normal aected

cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its

life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the discharge contains

enough power to alter device parameters or melt silicon junctions.

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of

sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric

components and accessories.

●To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.

●Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers

or packaging.

●Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.

●Place items on a grounded surface before removing them from their containers.

●Always be properly grounded when touching a sensitive component or assembly.

●Avoid contact with pins, leads, or circuitry.

●Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam.

This computer supports two security password features that are established through the Computer Setup

Utilities menu: administrator password and power-on password. When you establish only an administrator

password, any user can access all the information on the computer except Computer Setup. When you establish

only a power-on password, the power-on password is required to access Computer Setup and any other

information on the computer. When you establish both passwords, only the administrator password will give you

access to Computer Setup.

When both passwords are set, the administrator password can also be used in place of the power-on password

as an override to log in to the computer. This is a useful feature for a network administrator.

If you forget one or both passwords, you can clear all passwords by powering the system, opening the cover, o

temporarily removing the CLR_PSWD jumper, and booting once. This will erase the administrator and power-on

passwords. You must restore the jumper to create new passwords.

The computer’s memory (CMOS) stores information about the computer’s conguration conguration.

The CMOS jumper resets CMOS but does not clear the power-on and setup passwords.

CAUTION:

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 89. For information on the recovery options that are available using the recovery media, see

the computer. You can also contact information on the HP website. Go to nd 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 90.

●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 congures

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

the factory image if you replace the hard drive.

○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 high-quality

blank USB drive.ash

○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 nd

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 creating all of the recovery DVDs. HP nished
