4 Removal and replacement 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 screw driver
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 ex cables with extreme care; these cables tear
easily.
18 Chapter 4 Removal and replacement preliminary requirements
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 drive, shut down the computer. If you are unsure whether the computer is o
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 drive, place it in a static-proof bag.
Avoid exposing a drive to products that have magnetic elds, such as monitors or speakers.
Avoid exposing a drive to temperature extremes or liquids.

Service considerations 19
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 nger 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 aected 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 aects the electrostatic voltage levels generated by
dierent activities.
CAUTION: A product can be degraded by as little as 700 V.
Typical electrostatic voltage levels

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 eld service tools, such as cutters, screw drivers, and vacuums.
●
When xtures must directly contact dissipative surfaces, use xtures 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 o power and input signals before inserting or removing connectors or test equipment.
Grounding guidelines 21
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 exible 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 oor 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
oors or dissipative oor mats, use foot straps on both feet with a minimum of one megohm resistance
between the operator and ground. To be
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 computerop workstations with ground cords of one megohm resistance
●
Static-dissipative tables or oor mats with hard ties to the ground
●
Field service kits
eective, the conductive must be worn in contact with the skin.
●
Static awareness labels
●
Material-handling packages
●
Nonconductive plastic bags, tubes, or boxes
●
Metal tote boxes
●

The following table lists the shielding protection provided by antistatic bags and oor mats.

Antistatic plastics Bags 1,500 V
Carbon-loaded plastic Floor mats 7,500 V
Metallized laminate Floor mats 5,000 V
