Cables must be handled with extreme care to avoid damage. Apply only the tension required to
unseat or seat the cables during removal and insertion. Handle cables by the connector whenever
possible. In all cases, avoid bending, twisting, or tearing cables. Be sure that cables are routed in
such a way that they cannot be caught or snagged by parts being removed or replaced. Handle flex
cables with extreme care; these cables tear easily.

ENWW Preliminary replacement requirements 25

Drive handling

CAUTION: Drives are fragile components that must be handled with care. To prevent damage to

the computer, damage to a drive, or loss of information, observe these precautions:

Before removing or inserting a hard drive, shut down the computer. If you are unsure whether the
computer is off or in Hibernation mode, turn on the computer, and then shut it down using the
operating system.

Before handling a drive, be sure that you are discharged of static electricity. While handling a drive,
avoid touching the connector.

Handle drives on surfaces that are covered with at least one inch of shock-proof foam.

Avoid dropping drives from any height onto any surface.

After removing a hard drive, an optical drive, or a diskette drive, place it in a static-proof bag.

Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers.

Avoid exposing a drive to temperature extremes or liquids.

If a drive must be mailed, place the drive in a bubble pack mailer or other suitable form of protective
packaging and label the package “FRAGILE.”

Grounding guidelines

Electrostatic discharge damage

Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure
determine the degree of sensitivity. Networks built into many integrated circuits provide some
protection, but in many cases, ESD contains enough power to alter device parameters or melt
silicon junctions.

A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is neither felt nor heard, damage may have occurred.

An electronic device exposed to ESD may not be affected at all and can work perfectly throughout a
normal cycle. Or the device may function normally for a while, then degrade in the internal layers,
reducing its life expectancy.

CAUTION: To prevent damage to the computer when you are removing or installing internal

components, observe these precautions:

Keep components in their electrostatic-safe containers until you are ready to install them.

Use non-magnetic tools.

Before touching an electronic component, discharge static electricity by using the guidelines
described in this section.

Avoid touching pins, leads, and circuitry. Handle electronic components as infrequently as possible.

If you remove a component, place it in an electrostatic-safe container.

The following table shows how humidity affects the electrostatic voltage levels that are generated by
different activities.

CAUTION: A product can be degraded by as little as 700 V.

Typical electrostatic voltage levels

Relative humidity

Event 10% 40% 55%

Walking across carpet 35,000 V 15,000 V 7,500 V

ENWW Preliminary replacement requirements 27

Packaging and transporting guidelines

Follow these grounding guidelines when packaging and transporting equipment:

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

Protect ESD-sensitive parts and assemblies with conductive or approved containers or

●

packaging.

● Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.

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

●

Always be properly grounded when touching a component or assembly.

●

Store reusable ESD-sensitive parts from assemblies in protective packaging or non-conductive

●

foam.

Use transporters and conveyors made of anti-static belts and roller bushings. Be sure that

●

mechanized equipment that is used for moving materials is wired to ground and that proper
materials are selected to avoid static charging. When grounding is not possible, use an ionizer to
dissipate electric charges.

Workstation guidelines

Follow these grounding workstation guidelines:

● Cover the workstation with approved static-shielding material.

Use a wrist strap connected to a properly grounded work surface and use properly grounded

●

tools and equipment.

● Use conductive field service tools, such as cutters, screwdrivers, and vacuums.

When fixtures must directly contact dissipative surfaces, use fixtures made only of static-safe

●

materials.

● Keep the work area free of non-conductive materials, such as ordinary plastic assembly aids and

Styrofoam.

● Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle

these items only at static-free workstations.

Avoid contact with pins, leads, or circuitry.

●

● Turn off power and input signals before inserting or removing connectors or test equipment.

28 Chapter 4 Removal and replacement procedures ENWW

Equipment guidelines

Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.

● When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible

straps with a minimum of one megohm ±10% resistance in the ground cords. To provide proper
ground, wear a strap snugly against the skin at all times. On grounded mats with banana-plug
connectors, use alligator clips to connect a wrist strap.

When standing, use foot straps and a grounded floor mat. Foot straps (heel, toe, or boot straps)

●

can be used at standing workstations and are compatible with most types of shoes or boots. On
conductive floors or dissipative floor mats, use foot straps on both feet with a minimum of one
megohm resistance between the operator and ground. To be effective, the conductive strips
must be worn in contact with the skin.

The following grounding equipment is recommended to prevent electrostatic damage:

Antistatic tape

●

Antistatic smocks, aprons, and sleeve protectors

●

Conductive bins and other assembly or soldering aids

●

Nonconductive foam

●

● Conductive tabletop workstations with ground cords of one megohm resistance

● Static-dissipative tables or floor mats with hard ties to the ground

Field service kits

●

Static awareness labels

●

Material-handling packages

●

Nonconductive plastic bags, tubes, or boxes

●

● Metal tote boxes

● Electrostatic voltage levels and protective materials

The following table lists the shielding protection that is provided by antistatic bags and floor mats.

ENWW 73

Restore

In the event of hard drive failure, to restore your system to its factory image you will need a set of
recovery discs or a recovery flash drive that you can create using HP Recovery Manager. HP
recommends that you use this software to create either a set of recovery discs or a recovery flash
drive immediately after software setup.

If for some other reason you need to restore your system, this can be achieved using the HP
Recovery partition (select models only), without the need for recovery discs or a recovery flash drive.
To check for the presence of a recovery partition, click Start, right-click Computer, click Manage,
and then click Disk Management. If the recovery partition is present, a Recovery drive is listed in the
window.

CAUTION: HP Recovery Manager (partition, or discs/flash drive) restores only software that was

preinstalled at the factory. Software not provided with this computer must be reinstalled manually.

NOTE: Recovery discs have been included if your computer does not have a recovery partition.

Creating restore media

HP recommends that you create either a set of recovery discs or a recovery flash drive to be sure that
you can restore your computer to its original factory state if the hard drive fails, or if for any reason
you cannot restore using the recovery partition tools. Create these discs or the flash drive after setting
up the computer for the first time.

NOTE: HP Recovery Manager allows the creation of only one set of recovery discs or one recovery

flash drive. Handle these discs or flash drive carefully and keep them in a safe place.

NOTE: If your computer does not include an integrated optical drive, you can use an optional

external optical drive (purchased separately) to create recovery discs, or you can purchase recovery
discs for your computer from the HP Web site. If you use an external optical drive, it must be
connected directly to a USB port on the computer, not to a USB port on an external device, such as a
USB hub.

Guidelines:

Purchase high-quality DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs.

●

NOTE: Read-write discs, such as CD-RW, DVD±RW, double-layer DVD±RW, and BD-RE

(rewritable Blu-ray) discs, are not compatible with the Recovery Manager software.

The computer must be connected to AC power during this process.

●

Only one set of recovery discs or one recovery flash drive can be created per computer.

●

NOTE: If you are creating recovery discs, number each disc before inserting into the optical

drive.

If necessary, you can exit the program before you have finished creating the recovery discs or

●

recovery flash drive. The next time you open Recovery Manager, you will be prompted to
continue the backup creation process.

To create a set of recovery discs or a recovery flash drive:

1. Select Start > All Programs > Recovery Manager > Recovery Media Creation.

2. Follow the on-screen instructions.

74 Chapter 7 Backup and recovery ENWW

Performing a system restore

Recovery Manager software allows you to repair or restore the computer to its original factory state.
Recovery Manager works from recovery discs, a recovery flash drive, or from a dedicated recovery
partition (select models only) on the hard drive.

NOTE: A system restore needs to be performed if the computer hard drive has failed or if all

attempts to correct any functional computer issues fail. A system restore should be used as a final
attempt to correct computer issues.

Note the following when performing a system restore:

You can restore only the system that you have previously backed up. HP recommends that you

●

use HP Recovery Manager to create either a set of recovery discs or a recovery flash drive as
soon as you set up the computer.

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.

Recovery Manager restores 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.

Restoring using the dedicated recovery partition (select models only)

When using the dedicated recovery partition, there is an option to back up pictures, music and other
audio, videos and movies, recorded TV shows, documents, spreadsheets and presentations, e-mails,
Internet favorites and settings during this process.
