5Removal and replacement
procedures
Preliminary replacement requirements
Tools required
You will need the following tools to comple te the removal and replacement procedures:
● Magnetic screwdriver
● Phillips P0 and P1 screwdrivers
● Flat-bladed screwdriver
Service considerations
The following sections include some of the considerations
 that you should 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 th e work area to prevent damage.
Plastic parts
Using excessive force during disassembly and reassembly can dama ge plastic parts. Use care when
handling the plastic parts. Apply pressure only at  the points designated in the maintenance instructions.
30 Chapter  5   Removal and replacement procedures ENWW 
						

							
Cables and connectors
CAUTION:When servicing the computer, be sure th at 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 avoi d damage. Apply only the tension required to unseat
or seat the cables during removal and insertion. Ha ndle 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 remo ved 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 lo ss 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 disk ette 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 temp erature extremes or liquids.
If a drive must be mailed, place the drive in a bubb l e  p a c k  m a i l e r  o r  o t h e r  suitable form of protective
packaging and label th e package “FRAGILE.”

Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitiv e to electrostatic discharge (ESD). Circuitry design and structure
determine the degree of sens itivity. Networks built into many integr ated 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 fr om 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 electr ostatic-safe containers until you area 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 el ectrostatic voltage levels generated by different
activities.
CAUTION: A product can be degraded by as little as 700 V.

Packaging and transporting guidelinesFollow 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 co
nductive or approved containers or packaging.
● Keep ESD-sensitive parts in their containers unti
l 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 ground ing is not possible, use an ionizer to dissipate electric charges.
Workstation guidelines Follow these grounding workstation guidelines:
●Cover the workstation with approv
ed 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 material
s, 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 insert
ing or removing connectors or test equipment.
ENWW Preliminary replacement requirements 33 
						

							
Equipment guidelinesGrounding equipment must include either a wrist st rap or a foot strap at a grounded workstation.
● When seated, wear a wrist strap connected to a gr
ounded 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 time s. 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 workstatio
ns 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 reco mmended 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.

Metallized laminate Floor mats 5,000 V
