4 Removal and replacement procedures

preliminary requirements

Tools required

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

●

Flat-bladed screwdriver

●

Phillips P0 and P1 screwdrivers

●

Torx T8 screwdriver

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 29

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 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.”

30 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, and 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 nonmagnetic 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 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

Service considerations 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 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.

32 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 strips must be worn in contact with
the skin.

The following grounding equipment is recommended to prevent electrostatic damage:

●

Antistatic tapes

●

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 plastic Bags 1,500 V

Carbon-loaded plastic Floor mats 7,500 V

Metallized laminate Floor mats 5,000 V
