4 Removal and replacement

procedures

Preliminary replacement requirements

Tools required

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

●

Flat-bladed screwdriver

●

Magnetic screwdriver

●

Phillips P0 and P1 screwdrivers

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.

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.

Preliminary replacement requirements

29

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.”

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.

30 Chapter 4 Removal and replacement procedures

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

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

Preliminary replacement requirements

31

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, screwdrivers, and vacuums.

●

When fixtures must directly contact dissipative surfaces, use fixtures made only of static­safe 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.

32 Chapter 4 Removal and replacement procedures

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

7 Backup and recovery

Your computer includes tools provided by the operating system and HP to help you safeguard your
information and restore it if ever needed.

This chapter provides information on the following topics:

●

Creating a set of recovery discs or a recovery flash drive (Recovery Manager software feature)

●

Performing a system restore (from the partition, recovery discs, or a recovery flash drive)

●

Backing up your information

●

Recovering a program or driver

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.

Restore

89

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, and double-layer DVD±RW discs, are not

compatible with the Recovery Manager software.

●
