GENERAL SERVICE INFORMATION

The information in this book was prepared for the Compaq Deskpro 2000 Series of Personal Computers with MMX technologies and later models as well as Compaq Deskpro Workstations, Compaq Professional Workstations, Compaq Armada Notebooks, and Compaq Prosignia Notebooks.

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.

Tools Required - Desktop Computers and Workstations

TTorx T-15 and flat-blade screwdrivers

TLoopback plugs

TWrite-protected bootable diskette

TAnti-static wrist strap

Tools Required - Notebooks

TMagnetic flat-blade screwdriver, Torx T-8, and T-10 screwdrivers

T3/16-inch and 7-mm hex sockets or nut drivers

TSecurity wrench

TLoopback plugs

TWrite-protected bootable diskette

TAnti-static wrist strap

Protecting Yourself and the Computer

TTurn the computer off before disconnecting or installing any cables.

TWhen 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.

TFor 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.

Quick Troubleshooting Guide

1-1

TThe screws used in the computer are of different thread sizes and lengths; using the wrong screw in an application may damage the unit.

TAll data stored on a hard drive is lost when the drive is formatted.

Clearing CMOS

This procedure does not apply to portable computers.

1.Turn off the computer and any peripheral devices that are connected to it.

2.Disconnect the power cord from the electrical outlet and then from the computer.

CAUTION: The cooling fan is off only when the computer is turned off and the power cable has been disconnected. The cooling fan is always on in all other instances, such as when the computer is “On,” in “Standby,” or “Suspend” mode.

CAUTION: 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.

3.Remove the computer cover.

4.Reset the computer by one of the following methods depending on the model.

TIf the system board has a CMOS reset button, press the button and then release it to reset the CMOS.

TIf 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:

TInstalling the operating system.

TProviding and running all virus check programs.

TRunning Diagnostics on the hard drive.

TReloading the operating system as required.

TCopying over the operating system files as required.

TReformatting the hard drive as required.

1-2 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:

TTest Succeeded. Completion Code 0.

TTest Aborted. Completion Code 1 or 2.

TTest 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.
