Compaq Deskpro 2000 Series of Personal Computers. All replaceable components are identified in
Chapter 3, and removal/replacement instructions are presented in Chapters 5 and 6.
1.3.1 Design Overview
The desktop models of the Compaq Deskpro 2000 Series of Personal Computers have a conventional
design that uses a pan-type chassis to house the system board, expansion cards, power supply, and
mass storage devices. The chassis is supplemented by a riser board attached to the riser brace. The
riser board provides a mounting location for the expansion cards.
All internal components are accessible when the hood, held in place by two thumbscrews, is
removed. The front bezel is mounted to the front of the chassis. Torx T-15 screws are used
throughout the system.
The system board is easily removed from the side of the chassis after the hood and riser board are
removed. Details of the disassembly procedure for desktop models are found in Chapter 5, “Removal
and Replacement Procedures.”
The riser board mounts perpendicularly to the system board. Expansion boards are installed
horizontally into the riser board. A single screw attaches each expansion board to the rear panel of the
chassis.
The power supply is mounted in the right rear corner of the chassis. The power supply is held in
place by three Torx screws that are installed through the rear panel of the chassis.
The minitower models have a chassis designed to house the system board, riser board, option cards,
power supply, and mass storage devices. The use of a riser brace to hold the riser board, and any
expansion boards installed, allows for easy access to the system board. The power supply is mounted
in the top of the unit.
All internal components are immediately accessible when the side panel is removed.
The minitower’s tray-mounted system board is easily removed after taking off the side panel and
riser brace. Details of the disassembly procedure for minitower models are found in Chapter 6,
“Removal and Replacement Procedures.”
Detailed descriptions of the system components are presented in the sections that follow.

1.3.2 System Board
The desktop and minitower models of the Compaq Deskpro 2000 Series of Personal Computers have
a single system board configuration. The Pentium system board uses an Intel Pentium processor. The
Pentium II system board uses the Intel Pentium II processor. The processors are designed using
MMX technology. The desktop units of both systems have the I/O panel mounted to the system board
and is spared with the I/O panel. On the minitower, the system board is attached to a sliding tray and
is spared with the tray.
1.3.3 Processor
The Pentium system boards run at processor speeds of 166 MHz, 200 MHz, or 233 MHz depending on
the model. A computer with a processor speed of 166 MHz can be upgraded to a processor speed of
either 200 MHz or 233 MHz. A computer with processor speed 200 MHz can be upgraded to a
processor speed of 233 MHz.
The Pentium II system boards run at speeds of 233 MHz, 266 MHz, or 300 MHz. A Pentium II system
with a processor speed of 233 MHz can be upgraded to a processor speed of either 266 MHz or 300
MHz, and a Pentium II system with a processor speed 266 MHz can be upgraded to a processor speed
of 300 MHz.
Utilizing MMX technology in the design of the processors enhances the systems’ ability to take
advantage of the MMX instructions while preserving compatibility with existing software and
operating systems
1.3.4 System Memory
The system supports base (conventional) and extended memory. Operating systems such as MS-DOS,
OS/2, UNIX, and all application programs use base memory. For better performance, Windows NT,
OS/2, and UNIX, as well as many MS-DOS applications, use extended memory.
For proper system operation, the DIMMs must be industry standard 168-pin, 66-MHz or faster
unbuffered SDRAM DIMMs. The memory modules may also be unbuffered extended data out (EDO)
DIMMs. SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3) with a data access
time (clock to data out) of 9.0 ns or less. The DIMMs must also contain Joint Electron Device
Engineering Council (JEDEC) Serial Presence Detect (SPD) information. SDRAMS on DIMMs must
have a data width of x8, x16, or x32; x4 is not supported. The system will not start using unsupported
DIMMs or incompatible DIMM configurations. See Appendix H, “Intel 440LX Chipset Memory
limitations,” for incompatible and unsupported DIMM configurations. Refer to Chapters 5 and 6,
“Removal and Replacement Procedures,” for information on how to upgrade system memory.
1.3.5 Cache Memory
Cache memory is very fast memory used for temporarily storing data for fast access by the processor.
The faster the processor, the more need there is for faster temporary data storage. A 256 KB writethrough, direct-mapped secondary (L2) cache is integrated onto the system board on all Pentium
models. The L2 cache memory for the Pentium models may be increased to 512 KB with the addition
of an optional plug-in module on the system board.
1-6 Product Description
Page 19
L2 cache memory for all Pentium II models is integrated in the processor module with a capacity of
512 KB and is not upgradable.
1.3.6 Graphics Controllers
The purpose of a graphics controller is to generate the text and graphics images for the monitor
screen. The quality of the picture you see depends on the resolution of the monitor, the number of
colors the graphics controller can display, and the amount of graphics memory available. High
resolution graphics with many colors require that the graphics controller have its own memory
system.
The Pentium computers come with the S3 Trio64V2/GX Enhanced 64-bit graphics controller
integrated onto the system board and have 1 MB of SGRAM installed. Graphics memory on these
models may be upgraded to 2 MB with the addition of an optional memory module.
The Pentium II computer comes with the Matrox MGA-1064SG graphics accelerator integrated onto
the system board and has 2 MB of SGRAM installed. Graphics memory on these models may be
upgraded to 4 MB with the addition of an optional memory module.
Supported screen resolutions for the controller are listed in Chapter 8, “Specifications.”
1.3.7 Chipsets
VIA Chipset
The Pentium system uses the VIA Apollo VP2/AMD-640 chipset. This provides a high-speed, 32-bit
PCI/IDE (EIDE) interface, which supports the following:
■
Up to four PCI/IDE (EIDE) devices on the PCI bus
■
SDRAM and EDO DIMM support
■
ECC DIMM support
440LX Chipset
The Intel 440LX chipset is designed specifically for the Pentium II system. This provides support for
the latest technologies, including the following:
■
Up to four PCI/IDE (EIDE) devices on the PCI bus or four Ultra ATA devices

Page 20
1.3.8 System I/O
The onboard I/O controller integrates the functions for the serial and parallel ports, diskette drives,
the keyboard and mouse. This component provides support for the following:
■
Multimode bidirectional parallel port
❏
Standard mode: Centronics-compatible operation
❏

■
Integrated 8042-compatible keyboard controller
■
Industry-standard diskette drive controller that supports 360-kilobyte and 1.2-megabyte
5.25-inch drives
1.3.9 System BIOS
The system BIOS provides ISA and PCI compatibility. Contained in a flash memory device on the
system board, the BIOS provides both the Power-On Self-Test (POST) and PCI and EIDE autoconfiguration utilities.
The system BIOS is always “shadowed.” Shadowing allows any BIOS routines to be executed from
fast 64-bit onboard DRAM instead of from the slower 8-bit flash device.
PCI Auto-Configuration
The PCI auto-configuration utility works in conjunction with the Setup program to support using PCI
expansion boards in the system. When you turn on the computer power after installing a PCI board,
the BIOS automatically configures interrupts, I/O space, and PCI devices. If problems arise or you
wish to reconfigure the device, refer to Chapter 2, “Compaq Utilities,” which explains how to use the
Setup program. The PCI auto-configuration program complies with version 2.1 of the PCI BIOS
specification.
IDE/EIDE Auto-Configuration
If you install an IDE/EIDE drive into the computer, the IDE/EIDE auto-configuration utility
automatically detects and configures the drive for operation in the computer. This utility eliminates
the need to run the Setup program after you install an IDE/EIDE drive.
ISA Plug and Play Capability
ISA Plug and Play capability provides auto-configuration of Plug and Play ISA boards and resource
management for legacy (non–Plug and Play) ISA boards when used with Computer Setup or a Plug
and Play–compatible operating system like Microsoft’s Windows 95.
1-8 Product Description
Page 21
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS without
having to disassemble the system. The flash upgrade process can be accomplished by running a
utility from a diskette, a hard drive, or over a network.
The section on Flash ROM in Chapter 2, “Compaq Utilities,” explains how to run the BIOS upgrade
utility.
1.3.10 Expansion Slots
The computer has two dedicated 16-bit ISA-compatible slots, two dedicated PCI-compatible
expansion slots, and one “combination slot” that can be used by either a PCI or an ISA board. For
more information about expansion slots and installing expansion boards, see Chapters 5 and 6,
“Removal and Replacement Procedures.”
1.3.11 Power Supply
The power supply provides power for system requirements including onboard resources, expansion
boards, and drives. The desktop system supports a maximum of 145-watts of continuous power. The
minitower system supports a maximum of 185-watts of continuous power. The same power supply,
rated at 200-watts maximum output, provides for both system requirements. The power supply has
integrated surge protection to withstand a 2,000 volt power surge. A switch on the computer back
panel sets the power supply to operate at:
■
115 VAC (in the range of 100-120 VAC)
■
230 VAC (in the range of 200-240 VAC)
1.3.12 Diskette Drive Interface
The diskette drive interface is 8477 compatible and supports two storage devices (diskette or tape
drive).
1.3.13 Serial Port
The serial port is RS-232C compatible.
1.3.14 Parallel Port
The following parallel support modes are supported:
■
Bidirectional Standard Parallel Port (SPP)
■
Enhanced Parallel Port (EPP)
■

1.3.15 System Security
The system BIOS provides a power-on password option that is enabled through the Setup program.
The computer includes a cable lock provision that makes it possible to lock the computer cover in
place to prevent unauthorized access to the system jumpers and other internal components (a padlock
is not included). For more information on this and additional security features, refer Chapter 2,
“Compaq Utilities.”
1.3.16 Keyboard/Mouse Controller
The onboard 8042 I/O controller stores the keyboard and mouse controller code. Connectors for the
keyboard and mouse are located on the back panel.
1.3.17 Real-Time Clock and CMOS RAM
The onboard I/O controller provides a real-time clock and CMOS RAM. Chapters 5 and 6, “Removal
and Replacement,” provide information about installing a new battery.
You can set the time for the clock and the CMOS values by using the Setup program described in
Chapter 2, “Compaq Utilities.”
1.3.18 Power Supply Fan
For cooling, a fan is incorporated as part of the power supply at the rear of the computer chassis. The
fan draws air in through the front of the chassis and exhausts air out the rear of the chassis. This
provides adequate air flow across the processor.
To insure that the processor in a Pentium II minitower system receives adequate ventilation, an
internal air duct is installed in the front of the unit.
1.3.19 Speaker
An internal piezo speaker is mounted on the system board. The speaker provides audible error code
information (beep codes) during the Power-On Self-Test (POST) and as required by the software. See
Appendix F, “POST Error Messages,” for beep code information.

2.11.2 Fault Management
Fault Management features combine innovative hardware and software technology to prevent the loss
of critical data and minimize unplanned downtime.
When a fault occurs, the computer displays a Local Alert message containing a description of the
fault and any recommended actions. You can then view current system health by using Compaq
Insight Personal Edition. If the computer is connected to a network managed by Compaq Insight
Manager or other simple network management protocol (SNMP)–based management products (e.g.,
HP OpenView or IBM Tivoli TME10 NetView), the computer also sends a fault notice to the
network management application.
SMART II Hard Drive Fault Prediction
The SMART II hard drive monitors hard drive activity to predict failures before they occur. Fault
prediction and failure indication parameters, such as abnormal variations in spinup and seek times, or
non-correctable read and write errors, are tracked to determine the hard drive condition. Should these
errors become significant, the computer displays a warning message. The warning gives you time to
back up the hard drive and replace it prior to experiencing downtime or loss of data. The Prefailure
Warranty for SMART II hard drives allows you to replace these drives, free of charge, before the
drives fail.
SMART II hard drives are compliant with the Small Form Factor Committee Specification for SelfMonitoring, Analysis, and Reporting Technology (SMART) Version II. SMART is the industry
standard technology, pioneered by Compaq and originally called IntelliSafe, that allows you to
prevent data loss and minimize downtime, in concert with Compaq Insight Management Agents.
ECC Fault Prediction and Prefailure Warranty
When the computer encounters an excessive number of error checking and correcting (ECC) memory
errors, the screen displays a Local Alert message. This message contains detailed information about
the errant memory module, allowing you to take action before you experience non-correctable
memory errors. The Prefailure Warranty for ECC memory modules allows you to replace these
modules, free of charge, before the modules actually fail. ECC memory modules are optional on all
Compaq Deskpro personal computers.
✎
To use this feature, you must replace the standard DIMMs with ECC DIMMs.
Monitor Fault Diagnosis
New Compaq monitors detect when the operating temperature exceeds the normal range or when a
hardware fault occurs. Hardware faults may include the following:
■
Power voltage out of range
■
Power current out of range
■
Horizontal deflection
■
Vertical deflection
■
I/O controller operation failure
2-16 Compaq Utilities
Page 55
If the monitor detects one of these conditions, the computer will send an alert over the network to the
system administrator.
Proactive Backup
Proactive Backup software initiates a tape or PD-CD backup upon receiving notice of an impending
SMART hard drive failure.
The Seagate Backup Exec SMART Client works with Seagate Backup Exec tape backup software on
the server, or with Seagate Backup Exec software supporting the PD-CD drive. Together with the
Insight Management Agents, this software offers a Proactive Backup solution. For instructions on
configuring the Backup Exec SMART Client, contact your systems administrator or refer to the
Seagate Backup Exec documentation.
Cheyenne has also created an agent to support the Proactive Backup solution. The SMART Drive
Agent is the component that recognizes and reacts to the SMART II hard drive fault alerts. This agent
is an extension to the Microsoft Windows 95 tape backup agent for the standalone application
ARCsolo for Windows. This agent works with the SMART II hard drive to ensure that critical data
will be protected in the event of a hard drive failure.
Surge-Tolerant Power Supply
An integrated, surge-tolerant power supply provides greater reliability when the computer is hit with
an unpredictable power surge. This power supply is rated to withstand a power surge of up to 2,000
volts without incurring any system downtime or data loss.
2.11.3 Security Management
As access to a network increases, so does the risk of unauthorized access to critical information and
theft of valuable components. The Compaq personal computer provides a robust set of security
features to protect the computer and data from unauthorized access.
■
Physical security features such as the cable lock provision help prevent theft or unauthorized
access to internal components such as processor and memory.
■
Setup and Power-On Passwords help prevent unauthorized access to information stored on the
computer or the network.
■
DIMM configuration changes will trigger local and remote alert messages, providing timely
notice of unauthorized additions, changes, or removals. (This feature is supported on all Compaq
DIMMs and others that comply with the DIMM SPD standard.)
■
The Ownership Tag displays ownership information during system restart. The Ownership Tag
information can be entered or modified in Computer Setup and is protected by the Setup
Password.
■
Drive and media security features control access to the information stored on the computer and
can prevent unauthorized transfer of data to a diskette drive or other removable storage media
(e.g. LS-120, PD-CD). These features can also prevent startup from the removable media drives.
■
Device disabling features can prevent unauthorized transfer of data over fax/modems, serial
ports, parallel ports, or infrared ports.

✎
Remote ROM Flash
Your computer comes with reprogrammable flash ROM (Read Only Memory). By establishing a
Setup Password in Security Management, you can protect the ROM from being unintentionally
updated or overwritten. This is important to ensure computer operating integrity. Should you need or
want to upgrade your ROM, you may:
■
Order an upgraded ROMPaq diskette from Compaq.
■
Order the Support Software CD for Compaq Desktop, Portable, and Workstation Products.
■
Download the latest ROMPaq images from the Compaq World Wide Web site
(www.compaq.com).
CAUTION:
Password prevents unauthorized ROM upgrades.
For maximum ROM protection, be sure to establish a Setup Password. The Setup
2-18 Compaq Utilities
Page 57
Upgrading Flash ROM
To upgrade the ROM after you receive an upgraded ROMPaq diskette, complete the following steps:
1. Insert the ROMPaq diskette in the diskette drive, enter the correct command, and the computer
will prompt for the Setup Password.
2. Enter the Setup Password.
3. If the Setup Password is entered correctly, the ROMPaq utility will take over and run the flash
ROM upgrade.
✎
Do not turn off the power to your computer until the ROMPaq utility has completed the
upgrade process.
If the Setup Password is incorrectly entered, the procedure will terminate and no changes
will be made to the ROM.
4. When the utility finishes upgrading the ROM, remove the diskette from the diskette drive and
restart your computer.
Using Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote Compaq
Deskpro personal computers, directly from the centralized network management console. Enabling
the system administrator to perform this task remotely, on multiple computers, results in a consistent
deployment of and greater control over Deskpro ROM images over the network. It also results in
greater productivity and lower total cost of ownership.
Compaq created the Remote ROM Flash capability to be secure and fail-safe. All Deskpro ROMPaq
ROM images from Compaq are digitally signed to ensure authenticity and minimize potential
corruption. The ROM firmware includes a Boot Block that is protected during the flash process and
allows the Deskpro to be restarted, in the unlikely event of an unsuccessful ROM flash.
Remote ROM Flash is performed in two stages:
1. System administrator uses the Remote Management Setup software on a centralized
management console to prepare a Deskpro ROMPaq file.
2. System administrator uses a PC LAN management product, such as Microsoft SMS, Intel
LANDesk Manager, or Symantec Norton Administrator for Networks, to distribute and execute
the file over the network to remote Deskpros.
✎
Use of Remote ROM Flash requires an established Setup Password.
For more information on enabling Remote ROM Flash, refer to the online Remote Management Help.
Compaq Deskpro 2000 Series of Personal Computers 2-19
Page 58
FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash
failure, for example, if a power failure occurs during a ROM upgrade. The Boot Block is a flashprotected section of the ROM that checks to validate the system ROM each time power to the system
is turned on.
■
If the system ROM is valid, the system starts normally.
■
If the system ROM fails the validation check, the FailSafe Boot Block ROM provides enough
support to start the system from a ROMPaq diskette, which will program the system ROM with a
valid image.
Because there is no video or hard drive support from the Boot Block ROM, the keyboard lights
communicate information. When the Boot Block detects an invalid system ROM, the system sounds
a series of beeps (one long and three short) and flashes the three keyboard lights.
To recover the system after hearing the FailSafe Boot Block beeps, complete the following steps:
1. Remove any diskettes from the diskette drive and turn off the power.
2. Insert a ROMPaq diskette into the diskette drive.
3. Turn on power to the system
If a Setup Password has been established, the Caps Lock light will turn on.
4. Enter the Setup Password.
When the system successfully starts from the diskette and reprograms the ROM, the three
keyboard lights will turn on.

RELIMINARIES
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
4.1 Electrostatic Discharge Information
A sudden discharge of static electricity from your finger or other conductor can destroy staticsensitive 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 can work
perfectly throughout a normal cycle. The device 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.
4.1.1 Generating Static
Table 4-1 shows how different activities generate static electricity at different electrostatic voltage
levels.
Table 4-1
Typical Electrostatic Voltages
Relative Humidity
Event 10% 40% 55%
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl floor 12,000 V 5,000 V 3,000 V

Removing bubble pack from PCB 26,500 V 20,000 V 7,000 V
Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V
*Dual Inline Packaging (DIP) is the packaging around individual microcircuitry. These are then multi-packaged inside plastic
tubes, trays, or Styrofoam.

4.1.2 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 to electric components and accessories.
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 stations.
Place items on a grounded surface before removing them from their container.
Always be properly grounded when touching a sensitive component or assembly.
Avoid contact with pins, leads, or circuitry.
Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
4.1.3 Personal Grounding Methods
The method for grounding 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. When standing, use foot straps and
a grounded floor mat.

4-2 Removal and Replacement Preliminaries
Page 96
4.1.4 Grounding Workstations
To prevent static damage at the workstation, use the following precautions:
Cover the workstation with approved static-dissipative material. Provide a wrist strap connected
to the work surface and properly grounded tools and equipment.
Use static-dissipative mats, foot 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.
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.
4.1.5 Personal Grounding Equipment
Use the following equipment to prevent static electricity damage to equipment:
Wrist straps are flexible straps with a minimum of one-megohm +/- 10% resistance in the ground
cords. To provide proper ground, a strap must be worn snug against bare skin. The ground cord must
be connected and fit snugly into the banana plug connector on the grounding mat or workstation.
Heel straps/Toe straps/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.
4.1.6 Recommended Materials and Equipment
Other materials and equipment that are recommended for use in preventing static electricity include:
Antistatic tape

4.2 Routine Care
4.2.1 General Cleaning Safety
Precautions
1. Never use solvents or flammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and
then use the cloth on the component.
3. Always turn off the computer when cleaning with liquids or damp cloths.
4. Always turn off the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.
4.2.2 Cleaning the Computer Case
Follow all safety precautions in Section 4.2.1 before cleaning the computer.
To clean the computer case, follow the procedures described below:
To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping with
a cloth or swab dampened with clear water.
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will
evaporate quickly and not leave a residue.
After cleaning, always wipe the unit with a clean, lint-free cloth.
Occasionally, clean the air vents on the computer. Lint and other foreign matter can block the
vents and limit the airflow.

Use safety glasses equipped with side shields before attempting to clean debris from under the
as too much air pressure can dislodge lubricants applied under the wide keys.
If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool
is available through many electronic supply outlets.
CAUTION:
improperly removed or installed, the keyboard may not function properly.
Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed
Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are
out. Be careful not to wipe away lubricants necessary for proper key functions. Use tweezers to
remove any fibers or dirt in confined areas. Allow the parts to air dry before reassembly.
4.2.4 Cleaning the Monitor
Wipe the monitor screen with a clean cloth moistened with water or with a towelette designed for
cleaning monitors. Do not use sprays or aerosols directly on the screen, the liquid may seep into
the housing and damage a component. Never use solvents or flammable liquids on the monitor.
To clean the monitor body, follow the procedures in Section 4.2.2
4.2.5 Cleaning the Mouse
Before cleaning the mouse, ensure that the power to the computer is turned off.

4.3 Service Considerations
Listed below are some of the considerations that you should keep in mind during the disassembly and
assembly of the computer.
4.3.1 Tools and Software Requirements
To service the computer, you need the following:
Torx T-15 screwdriver
Flat-bladed screwdriver
Diagnostics software
Tool kit, Compaq part number 100767-001 (includes case utility tool, connector removal tool,
and loop-back plugs)
4.3.2 Screws
The screws used in the computer are not interchangeable. They may have standard or metric threads
and may be of different lengths. The standard screws have a silver finish, while the metric screws
have a black finish. If an incorrect screw is used during the reassembly process, it can damage the
unit. Compaq strongly recommends that all screws removed during disassembly be kept with the part
that was removed, then returned to their proper locations.
✎
As each subassembly is removed from the computer, it should be placed away from the
work area to prevent damage.
4.3.3 Cables and Connectors
Most cables used throughout the unit are flat, flexible cables. These cables must be handled with 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 the cables are routed in such a way that they
cannot be caught or snagged by parts being removed or replaced.
CAUTION:
reassembly process. Improper cable placement can damage the computer.
When servicing this computer, ensure that cables are placed in their proper location during the
