4Removal and Replacement

Preliminaries

This chapter provides essential information for proper and saferemoval and replacement service.

4.1 Tools RequiredYou will need the following tools to complete the removal andreplacement procedures:

Magnetic screwdriver

Phillips P0 screwdriver

Torx T8 screwdriver

Tool kit (includes connector removal tool, loopback plugs,and case utility tool)



65/148


Removal and Replacement Preliminaries

4.2 Service ConsiderationsThe following sections include some of the considerations that

you should keep in mind during disassembly and assemblyprocedures.

As you remove each subassembly from the notebook, place thesubassembly (and all accompanying screws) away from the workarea to prevent damage.

Plastic Parts

Using excessive force during disassembly and reassembly candamage plastic parts. Use care when handling the plastic parts.Apply pressure only at the points designated in the maintenanceinstructions.

Cables and ConnectorsCables must be handled with extreme care to avoid damage.Apply only the tension required to unseat or seat the cablesduring removal and insertion. Handle cables by the connector

whenever possible. In all cases, avoid bending, twisting, ortearing cables. Ensure that cables are routed in such a way thatthey cannot be caught or snagged by parts being removed orreplaced. Handle flex cables with extreme care; these cables teareasily.

CAUTION: When servicing the notebook, ensure that cables areplaced in their proper locations during the reassembly process.Improper cable placement can damage the notebook.



66/148



4.3 Preventing Damage toRemovable Drives

Removable drives are fragile components that must be handledwith care. To prevent damage to the notebook, damage to aremovable drive, or loss of information, observe the followingprecautions:

Before removing or inserting a hard drive, shut down thenotebook. If you are unsure whether the notebook is off or inHibernation, turn the notebook on, then shut it down.

Before removing a diskette drive or optical drive, ensure thata diskette or disc is not in the drive. Ensure that the opticaldrive tray is closed.

Before handling a drive, ensure that you are discharged ofstatic electricity. While handling a drive, avoid touching theconnector.

Handle drives on surfaces that have at least one inch ofshock-proof foam.

Avoid dropping drives from any height onto any surface.

After removing a hard drive, CD-ROM drive, or a diskettedrive, place it in a static-proof bag.

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

Avoid exposing a drive to temperature extremes or to liquids.

If a drive must be mailed, place the drive in a bubble packmailer or other suitable form of protective packaging andlabel the package Fragile: Handle With Care.



67/148



4.4 Preventing Electrostatic DamageMany electronic components are sensitive to electrostatic

discharge (ESD). Circuitry design and structure determine thedegree of sensitivity. Networks built into many integrated circuitsprovide some protection, but in many cases the discharge containsenough power to alter device parameters or melt silicon junctions.

A sudden discharge of static electricity from a finger or otherconductor can destroy static-sensitive devices or microcircuitry.Often the spark is neither felt nor heard, but damage occurs.

An electronic device exposed to electrostatic discharge may notbe affected at all and can work perfectly throughout a normal

cycle. Or the device may function normally for a while, thendegrade in the internal layers, reducing its life expectancy.

4.5 Packaging and TransportingPrecautions

Use the following grounding precautions when packaging andtransporting equipment:

To avoid hand contact, transport products in static-safecontainers, such as tubes, bags, or boxes.

Protect all electrostatic-sensitive parts and assemblies withconductive or approved containers or packaging.

Keep electrostatic-sensitive parts in their containers until theparts arrive at static-free workstations.

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

Always be properly grounded when touching a sensitivecomponent or assembly.



68/148



Store reusable electrostatic-sensitive parts from assemblies inprotective packaging or nonconductive foam.

Use transporters and conveyors made of antistatic belts androller bushings. Ensure that mechanized equipment used formoving materials is wired to ground and that proper materialsare selected to avoid static charging. When grounding is notpossible, use an ionizer to dissipate electric charges.

4.6 Workstation PrecautionsUse the following grounding precautions at workstations:

Cover the workstation with approved static-dissipativematerial (refer to Table 4-2).

Use a wrist strap connected to a properly grounded worksurface and use properly grounded tools and equipment.

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

When using fixtures that must directly contact dissipativesurfaces, only use fixtures made of static-safe materials.

Keep the work area free of nonconductive materials, such asordinary plastic assembly aids and Styrofoam.

Handle electrostatic-sensitive components, parts, andassemblies by the case or PCM laminate. Handle these itemsonly at static-free workstations.

Avoid contact with pins, leads, or circuitry.

Turn off power and input signals before inserting or removingconnectors or test equipment.



69/148



4.7 Grounding Equipment and MethodsGrounding 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 ofone megohm 10% resistance in the ground cords. Toprovide proper ground, wear a strap snugly against the skinat all times. On grounded mats with banana-plug connectors,connect a wrist strap with alligator clips.

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 shoesor boots. On conductive floors or dissipative floor mats, usefoot straps on both feet with a minimum of one-megohmresistance between the operator and ground. To be effective,the conductive strips must be worn in contact with the skin.

Other grounding equipment recommended for use in preventingelectrostatic damage includes:

Antistatic tape

Antistatic smocks, aprons, and sleeve protectors

Conductive bins and other assembly or soldering aids

Nonconductive foam

Conductive tabletop workstations with ground cords ofone-megohm resistance

Static-dissipative tables or floor mats with hard ties tothe ground

Field service kits

Static awareness labels

Material-handling packages
