4 Removal and replacement procedures

preliminary requirements

Tools required

You will need the following tools to complete the removal and replacement procedures:

Flat-bladed screw driver

●

Magnetic screw driver

●

Phillips P0 and P1 screw drivers

●

Service considerations

The following sections include some of the considerations that you must keep in mind during
disassembly and assembly procedures.

NOTE: As you remove each subassembly from the computer, place the subassembly (and all

accompanying screws) away from the work area to prevent damage.

Plastic parts

CAUTION: Using excessive force during disassembly and reassembly can damage plastic parts.

Use care when handling the plastic parts. Apply pressure only at the points designated in the
maintenance instructions.

Tools required 27

Cables and connectors

CAUTION: When servicing the computer, be sure that cables are placed in their proper locations

during the reassembly process. Improper cable placement can damage the computer.

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.

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, turn the computer on, and then shut it down through the operating
system.

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

Before removing a diskette drive or optical drive, be sure that a diskette or disc is not in the drive and
be sure that the optical drive tray is closed.

Handle drives on surfaces 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 an internal 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.”

28 Chapter 4 Removal and replacement procedures preliminary requirements

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.

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 little 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 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

Walking across vinyl floor 12,000 V 5,000 V 3,000 V

Motions of bench worker 6,000 V 800 V 400 V

Removing DIPS from plastic tube 2,000 V 700 V 400 V

Removing DIPS from vinyl tray 11,500 V 4,000 V 2,000 V

Removing DIPS from Styrofoam 14,500 V 5,000 V 3,500 V

Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V

Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V

Grounding guidelines 29

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 nonconductive

●

foam.

Use transporters and conveyors made of antistatic belts and roller bushings. Be sure that

●

mechanized equipment 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, screw drivers, and vacuums.

●

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

●

materials.

Keep the work area free of nonconductive 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.

●

30 Chapter 4 Removal and replacement procedures preliminary requirements

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 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 provided by antistatic bags and floor mats.

Material Use Voltage protection level

Antistatic plastics Bags 1,500 V

Carbon-loaded plastic Floor mats 7,500 V

Metallized laminate Floor mats 5,000 V

Creating recovery media with HP Recovery Disc Creator

HP Recovery Disc Creator is a software program that offers an alternative way to create recovery
media. After you successfully set up the computer, you can create recovery media using HP
Recovery Disc Creator. This recovery media performs a system recovery if the hard drive becomes
corrupted. A system recovery reinstalls the original operating system and the software programs
installed at the factory, and then configures the settings for the programs.

HP Recovery Disc Creator can create two kinds of recovery DVDs as follows:

Windows DVD—Installs the operating system without additional drivers or applications.

●

Choosing this selection creates a DVD that restores the original operating system and the
software programs installed at the factory.

Driver DVD—Installs specific drivers and applications only, in the same way that the HP

●

Software Setup utility installs drivers and applications.

Creating recovery media

NOTE: Operating system recovery media can be created only once. Thereafter, the option to create

that media will not be available.

1. Select Start > All Programs > Security and Protection > HP Recovery Disc Creator.

2. Select Driver DVD or Windows DVD.

3. From the drop-down menu, select the drive for burning the recovery media.

4. Click the Burn button to start the burning process.

Backing up your information

Recovery after a system failure is as good as your most recent backup. Immediately after software
setup, you should create system repair discs (select models only) using HP Recovery Disc Creator
using the installed optical drive (select models only) or an optional external optical drive and back up
your system. 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. The system repair discs (select models only)
are used to start up (boot) the computer and repair the operating system in case of system instability
or failure. Your initial and subsequent backups allow you to restore your data and settings if a failure
occurs.

You can back up your information to an optional external hard drive, a network drive, or discs.

Note the following when backing up:

Store personal files in the Documents library, and back it 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.

When backing up to discs, use any of the following types of discs (purchased separately): CD-R,

●

CD-RW, DVD+R, DVD+R DL, DVD-R, DVD-R DL, or DVD±RW. The discs you use will depend
on the type of optical drive you are using.

Creating recovery media with HP Recovery Disc Creator 89

NOTE: DVDs and DVDs with double-layer (DL) support store more information than CDs, so

using them for backup reduces the number of recovery discs required.
