REMOVAL & REPLACEMENT

Preliminary Considerations

Electrostatic Discharge

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 (ESD) may not be affected at all and will work perfectly
throughout a normal cycle. Or it may function normally for a while, then degrade in the internal layers,
reducing its life expectancy.

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.

Generating Static

The table below shows the different amounts of static electricity generated by different activities .

Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V

NOTE: 700 volts can degrade a product!

Preventing Electrostatic Damage to Equipment

Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
sensitivity. The following proper packaging and grounding precautions are necessary to prevent damage:

■ Protect all electrostatic parts and assemblies with conductive or approved containers

or packaging.

■ Keep electrostatic sensitive parts in their containers until they arrive at static-free

stations.

■ Place items on a grounded surface before removing them from their container.

■ Always be properly grounded when touching a sensitive component or assembly.

■ Place reusable electrostatic-sensitive parts from assemblies in protective packaging

or conductive foam.

Use transporters and conveyors made of antistatic belts and metal roller bushings. Mechanized
equipment used for moving materials must be wired to ground and proper materials selected to avoid
static charging. When grounding is not possible, use an ionizer to dissipate electric charges.

top of the page.

Preventing Damage to Drives

To prevent static damage to hard drives, use the following precautions:

■ Handle drives gently, using static-guarding techniques.

Grounding Methods

The method for grounding must include a wrist strap or a foot strap at a grounded workstation. When
seated, wear a wrist strap connected to a grounded system. When standing, use footstraps and a

■ Store drives in the original shipping containers.

■ Avoid dropping drives from any height onto any surface.

■ Handle drives on surfaces that have at least one inch of shock-proof foam.

■ Always place drives PCB assembly side down on the foam.

grounded floor mat.

Static-Shielding Protection Levels

Method

Grounding Workstations

To prevent static damage at the workstation, use the following precautions:

Voltages

■ Cover the workstation with approved static-dissipative material. Provide a wrist strap

Antistatic Plastic Carbon-Loaded

Plastic

connected to the work surface and properly grounded tools and equipment.

■ Use static-dissipative mats, heel straps, or air ionizers to give added protection.

■ Handle electrostatic sensitive components, parts, and assemblies by the case or PCB

laminate. Handle them only at static-free workstations.

■ Avoid contact with pins, leads, or circuitry.

■ Turn off power and input signals before inserting and removing connectors or test

equipment.

■ Use fixtures made of static-safe materials when fixtures must directly contact

dissipative surfaces.

■ Keep work area free of nonconductive materials such as ordinary plastic assembly

aids and Styrofoam.

■ Use field service tools, such as cutters, screwdrivers, and vacuums, that are

conductive.

■ Use a portable field service kit with a static dissipative vinyl pouch that folds out of a

work mat. Also use a wrist strap and a ground cord for the work surface. Ground the
cord to the chassis of the equipment undergoing test or repair.

Grounding Equipment

Use the following equipment to prevent static electricity damage to the equipment:

Wrist Straps are flexible straps with a minimum of 1 megohm ±10% resistance to the ground cords. To
provide proper ground, a strap must be worn snug against the skin. On grounded mats without banana­plug connectors, connect a wrist strap with alligator clips.

Heelstraps/Toestraps/Bootstraps can be used at standing workstations and are compatible with most
types of boots and shoes. On conductive floors or dissipative floor mats, use them on both feet with a
minimum of 1 megohm resistance between operator and ground. To be effective, the conductive strips
must be worn in contact with the skin.

Recommended Materials and Equipment

Other materials and equipment that are recommended for use in preventing static electricity include:

■ Antistatic tape

■ Antistatic smocks, aprons, or sleeve protectors

■ Conductive bins, and other assembly or soldering aids

■ Conductive foam

■ Conductive tabletop workstations with ground cord of 1 megohm of resistance

■ Static dissipative table or floor mats with hard tie to ground

■ Field service kits

■ Static awareness labels

■ Wrist straps and footwear straps providing 1 megohm ±10% resistance

■ Material handling packages

■ Conductive plastic bags

■ Conductive plastic tubes

■ Conductive tote boxes

■ Metal tote boxes

■ Opaque shielding bags

■ Transparent metallized shielding bags

Service Particulars

Listed below are some details that should be kept in mind during the disassembly and reassembly of the
computer.

Tool Requirements

■ Phillips screwdriver

■ Needle-nose pliers

■ Flat-bladed screwdriver

■ Compaq Utilities software

Screws

The screws used in these products are not interchangeable. If an incorrect screw is used during the
reassembly process, it could cause damage to the unit. Compaq strongly recommends that all screws
removed during the disassembly process be kept with the part that was removed, then returned to their
proper locations.

IMPORTANT: As each subassembly is removed from the computer, it should

be placed away from the work area to prevent damage.

Cables and connectors

Most cables used throughout the unit are ribbon cables. These must be handled with extreme care to
avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal
from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending,
twisting, or tearing the cables, and ensure that they are placed in such a way that they cannot be caught
or snagged by parts being removed or replaced.

l

CAUTION: When servicing these computers, ensure that cables
are placed in their proper location during the reassembly process.
Improper cable placement can cause severe damage to the unit.

TROUBLESHOOTING

Power-On Self Test (POST)

POST is a series of diagnostic tests that run automatically when the system is turned on. After the

computer is turned on, POST checks the following assemblies to ensure that the computer system is
properly functioning:

■ Keyboard

■ System board

■ Memory modules

■ Video memory

■ Diskette drives

■ Hard drive

■ Power supply

POST also detects the type of mass storage devices installed in the computer.

If POST finds an error in the system, an error condition is indicated by an audible and/or visual
message. The table below gives explanations of the error codes and a recommended course of action.

NOTE

If your model doesn't have internal speakers, an external speaker must
be plugged into the speaker output connector to hear any beeps during
POST.

Click a link below to find the probable cause and recommended action for a given error message.

IMPORTANT

Retest the system after completing each step. If the problem has
been resolved, do not proceed with the remaining steps.

Resolving Hardware Conflicts

Hardware conflicts may occur when two or more peripheral devices attempt to use the same hardware
resources. Interrupts, I/O addresses, and DMA channels are the most common hardware resources
used by peripheral devices. For example, the factory default settings for the MIDI port audio interface
are:

loaded.

Restart the system and make sure the DVD
drive drivers are loaded.

Base I/O address 220H
MIDI Port Base I/O address 330H
Interrupt IRQ 5
8-bit DMA Channel 1

When different peripheral devices use the same hardware resources at the same time, the devices
and/or the system may not function properly. Although PCI devices are required to be capable of
sharing IRQs with other PCI devices, conflict may still arise at the software level. In this case, contact
the vendor for updated drivers.

You can resolve hardware conflicts by ensuring that no devices are configured to use the same
hardware resources. These resources can either be dipswitch or jumper settings on the peripheral
card or software configurable resources. The
