The Armada E500 and Armada V300 computers use an electrical fan for
ventilation. The fan is controlled by a temperature sensor and is designed
to turn on automatically when high temperature conditions exist. These
conditions are affected by high external temperatures, system power
consumption, power management/battery conservation configurations,
battery fast charging, and software applications. Exhaust air is displaced
through the ventilation grill located on the right side of the computer.

The Power-On Self-Test (POST) is a series of tests that run every time
the computer is turned on. POST verifies that the system is configured
and functioning properly.

To run POST, complete the following steps:

1. Complete the preliminary steps (Section 2.1).

2. Turn on the computer.

If POST does not detect any errors, the computer beeps once or twice to
indicate that POST has run successfully. The computer boots from the
hard drive or from a bootable diskette if one is installed in the diskette
drive.

2.4 POST Error Messages

If the system is not functioning well enough to run POST, or if the
display is not functioning well enough to show POST error messages,
refer to the Troubleshooting tables in Section 2.6.

If POST detects an error, one of the following events occur:



A message with the prefix "WARNING" appears, informing you
where the error occurred. The system pauses until you press F1 to
continue.



A message with the prefix "FATAL" appears, informing you where
the error occurred. After the message, the system emits a series of
beeps, then stops.

The system emits a series of beeps, then stops.

Warning messages indicate that a potential problem, such as a system
configuration error, exists. When F1 is pressed, the system should
resume. You should be able to correct problems that produce WARNING
messages.

EMOVAL AND REPLACEMENT

P

RELIMINARIES

This chapter provides essential information for proper and safe removal
and replacement service.

4.1 Tools Required

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

Magnetic screwdriver

■

Torx T-8 screwdriver

■

Phillips screwdriver (for screw securing diskette drive bezel to base

■

assembly on Armada V300 only)
7-mm hex socket (for bushing guides)

■

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

■

utility tool)

4.2 Service Considerations

Listed below are some of the considerations that you should keep in
mind during disassembly and assembly procedures.

IMPORTANT:

place it (and all accompanying screws) away from the work area to
prevent damage.

Plastic Parts

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.

As you remove each subassembly from the computer,

Removal and Replacement Preliminaries"-



Cables and Connectors

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. Ensure 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; they
tear easily.

CAUTION:

placed in their proper location during the reassembly process.

When servicing the computer, ensure that cables are

Improper cable placement can damage the computer.

4.3 Preventing Damage to Removable Drives

Removable drives are fragile components that must be handled with
care. To prevent damage to the computer, damage to a removable 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, then shut it down.

Before removing a diskette drive or CD-ROM drive, ensure that a

■

diskette or disc is not in the drive. Ensure that the CD-ROM tray is
closed.

Before handling a drive, ensure that you are discharged of static

■

electricity. While handling a drive, avoid touching the connector.
Handle drives on surfaces that have at least one inch of shock-proof

■

foam.
Avoid dropping drives from any height onto any surface.

■

After removing a hard drive, place it into a static-proof bag.

■

After removing a CD-ROM drive or a diskette drive, place it into a

■

static-proof bag.
Do not use excessive force when inserting a drive into a drive bay.

■

After inserting a hard drive into the hard drive bay, always reinsert

■

either the original hard drive security plate or the tamper-resistant
security plate to prevent the hard drive from accidentally
disconnecting.

"-

Removal and Replacement Preliminaries

Avoid exposing a hard drive to products that have magnetic fields

■

such as monitors or speakers.
Avoid exposing a drive to temperature extremes or to liquids.

■

If a drive must be mailed, do the following: place the drive into a

■

bubble pack mailer or other suitable form of protective packaging;
label the package “Fragile: Handle With Care.”

4.4 Preventing Electrostatic Damage

Many 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 the discharge contains enough power to
alter device parameters or melt silicon junctions.

A sudden discharge of static electricity from a finger or other conductor
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 not be affected at all and can work
perfectly throughout a normal cycle. It may function normally for a
while, then degrade in the internal layers, reducing its life expectancy.

4.5 Packaging and Transporting Precautions

Use the following grounding precautions when packaging and
transporting equipment:

To avoid hand contact, transport products in static-safe containers

■

such as tubes, bags, or boxes.
Protect all electrostatic-sensitive parts and assemblies with

■

conductive or approved containers or packaging.
Keep electrostatic-sensitive parts in their containers until they arrive

■

at static-free workstations.
Place items on a grounded surface before removing them from their

■

container.
Always be properly grounded when touching a sensitive component

■

or assembly.

Removal and Replacement Preliminaries"-

!

Place reusable electrostatic-sensitive parts from assemblies in

■

protective packaging or non-conductive foam.
Use transporters and conveyers made of antistatic belts and roller

■

bushings. Ensure that mechanized equipment used for moving
materials is wired to ground, and that proper materials were selected
to avoid static charging. When grounding is not possible, use an
ionizer to dissipate electric charges.

4.6 Workstation Precautions

Use the following grounding precautions at workstations:

Cover the workstation with approved static-dissipative material

■

(refer to Table 4-2 later in this chapter).
Use a wrist strap connected to a properly grounded work surface and

■

use properly grounded tools and equipment.
Use field service tools, such as cutters, screwdrivers, and vacuums

■

that are conductive.
When using fixtures that must directly contact dissipative surfaces,

■

use fixtures made of static-safe materials only.
Keep work area free of nonconductive materials such as ordinary

■

plastic assembly aids and Styrofoam.
Handle electrostatic-sensitive components, parts, and assemblies by

■

the case or PCM laminate. Handle them 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.

4.7 Grounding Equipment and Methods

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 megaohm

±

10% resistance in the ground cords. To provide proper ground,
wear a strap snug against the skin at 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 shoes or boots. On
conductive floors or dissipative floor mats, use them 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.

Other grounding equipment recommended for use in preventing

■

electrostatic damage include:
Antistatic tape

■

Antistatic smocks, aprons, or sleeve protectors

■

Conductive bins and other assembly or soldering aids

■

Non-conductive foam

■

Conductive tabletop workstations with ground cord of one-megohm

■

resistance
Static-dissipative table or floor mats with hard tie to ground

■

Field service kits

■

Static awareness labels

■

Material-handling packages

■

Non-conductive plastic bags, tubes, or boxes

■

Metal tote boxes

■
