✎
Not all features are available on all Compaq products.
Troubleshooting Procedures
The flowcharts listed in Chapters 2 and 3 use the building-block concept, where flowchart 1 is the
first flowchart to which you should refer. If, during the debug process, you find yourself in a bind,
refer back to flowchart 1 to determine which potential problems you can rule out.

Protecting Yourself and the Computer
T
Turn the computer off before disconnecting or installing any cables.
T
When the computer is connected to an AC power source there is always voltage applied to
the system board. You must disconnect the power cord from the power source before
opening the computer to prevent system board or component damage.
T
For personal safety and to ensure that the computer does not overheat, Compaq
recommends that you install the computer cover or access panel before turning on the
computer.

If the system board uses jumpers, remove the E50 jumper from pins 1 and 2 for
60 seconds; then replace the jumper.
Customer Responsibilities
Check the service contract and verify that the customer has taken care of these items:

Reformatting the hard drive as required.
General Service Information
POST Power-On Sequence
When a Compaq Personal Computer or workstation is turned on, the computer reads its first
instructions from memory. It finds the instructions from the power-on restart vector addressed in
ROM and begins executing those instructions. The instructions begin with a series of ROMresident diagnostic tests called the Power-On Self-Test (POST) to determine if the computer is
operational and ready to accept an operating system. The normal checking procedure for POST
includes:
1. BIOS memory is tested and initialized (the first 128K of RAM is not displayed). If the system
does not pass the first memory check, an immediate error message is displayed and the
initialization process stops. The cause of a failure at this stage might be a problem with the
ROM, the system board, the CPU, or memory.
2. The system board and bus devices are quick-tested to determine if the interrupt controllers,
DMA controllers, keyboard controller, video display controller, interval timers, diskette drive
controller, serial and parallel port controller, and fixed disk controller are all properly installed
and are functioning properly.
3. The remaining memory is tested and the count displayed on the monitor only when starting the
machine from the off mode. You should verify that the memory displayed corresponds with the
memory installed in the computer.
4. The keyboard, drives, and their controllers are initialized and tested. Test results are shown via
the LEDs on the keyboard and computer case.
5. CMOS memory is checked for configuration, time, and date. If the CMOS memory parameters
do not match the actual system configuration, a "162-System Options" error or a “System
CMOS” error will be displayed with instructions for restarting the computer.
6. The speaker will sound two short beeps or will display the Compaq splash screen when the
POST has been successfully completed. Refer to the POST error messages when error messages
are displayed on the screen or when beep patterns are sounded.
Compaq Drive Protection System
The Compaq Drive Protection System (DPS) is a diagnostic tool built into the hard drives
installed in select Compaq Deskpro computers and workstations. DPS is designed to help
diagnose problems that might result in unwarranted hard drive replacement.
When Compaq Deskpro Computers and workstations are built, each installed hard drive is tested
using DPS and a permanent record of key information is written onto the drive. Each time DPS is
run, test results are written to the hard drive. This information may be used to help diagnose the
hard drive and the computer system.
Running DPS will not affect any programs or data stored on the hard drive. The test resides in the
hard drive firmware and can be executed even if the computer will not boot to an operating
system. The time required to execute the test depends on the manufacturer and size of the hard
drive; in most cases, the test will take approximately 2 minutes per gigabyte.
DPS should be used when you suspect a hard drive problem. If the computer reports a SMART
Hard Drive Detect Imminent Failure message, there is no need to run DPS; instead, back up the
information on the hard drive and replace the hard drive.
Quick Troubleshooting Guide
1-3
Accessing DPS Through Compaq Diagnostics for Windows
To access DPS through Compaq Diagnostics for Windows, perform the following steps:
1. Turn on the computer and select My Computer→Control Panel→Compaq Diagnostics.
A choice of five possible headings appears in the Diagnostics screen: Overview, Test, Status,
Log, and Error.
2. Select Test→Type of Test
A choice of three tests appear: Quick Test, Complete Test, and Custom Test.
3. Select Custom Test.
A choice of two test modes is offered: Interactive Mode and Unattended Mode.
4. Select Interactive Test→Storage→Hard Drives.
5. Select the specific drive(s) to be tested→Drive Protection System Test→Begin Testing.
When the test has been completed, one of three messages will be displayed for each of the drives
tested:
T
Test Succeeded. Completion Code 0.
T
Test Aborted. Completion Code 1 or 2.
T
Test Failed. Drive Replacement Recommended. Completion Code 3 through 14.
If the test failed, the completion code should be recorded for help in diagnosing the computer
problem.
Compaq Configuration Record Utility
Compaq Configuration Record Utility is an online information-gathering tool similar to other
Compaq management tools that run on computers. It gathers critical hardware and software
information from various sources to give a complete view of the computer. Configuration Record
Utility delivers comprehensive configuration capture, provides a means for automatically
identifying and comparing configuration changes, and has the ability to maintain a computer
configuration history. The information can be saved as a history of multiple sessions.
This utility was developed to allow resolution of problems without taking the computer off-line
and to assist in maximizing computer availability. The information obtained by the utility is useful
in troubleshooting computer problems, and streamlines the service process by enabling quick and
easy identification of computer configurations, which is the first step in resolving service cases.
The Compaq Configuration Record Utility is accessed via an icon in the Control Panel. When
running the utility, information is automatically gathered on such items as the operating system
version number, operating system parameters, and the operating system startup files. The utility
then combines this information with information on the hardware configuration to deliver a
comprehensive view of the computer.
