preface ABOUT THIS GUIDE This Compaq Service Reference Guide is a troubleshooting and repair guide that can be used for reference when servicing the Compaq Deskpro Personal Computers and Compaq Intel-based Workstations. Only authorized technicians trained by Compaq should attempt to repair this equipment. Compaq Computer Corporation reserves the right to make changes to all Compaq Personal Computers and Workstations without notice.
Technician Notes WARNING: Only authorized technicians trained by Compaq should attempt to repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly/module level repair. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.
chapter 1 INSTALLING THE OPERATING SYSTEM Depending on the model, Microsoft Windows 95, 98, Microsoft Windows 2000 Professional, or Microsoft Windows NT is preinstalled on the computer and will be configured automatically the first time the computer is turned on. CAUTION: Do not add optional hardware devices to your computer until the operating system is successfully installed. Doing so may cause errors and may prevent the operating system from installing properly.
1.2 Microsoft Windows NT Workstation 4.0 or Windows 2000 Professional The first time you turn on your computer, the operating system is automatically installed for you. This takes approximately 10 to 20 minutes, depending on the system hardware configuration. At the beginning of the installation process, the user is prompted to select the appropriate language for the operating system. Read and follow the instructions that appear on the screen to complete the installation. 1.2.
1.3 Converting to NTFS 1.3.1 Windows NT Workstation 4.0 The hard drive included with a Windows NT Workstation 4.0 model contains a primary FAT16 partition on which the operating system and Compaq software are installed. The rest of the hard drive is divided into one or more additional partitions. Because FAT16 only supports partitions up to 2 GB, converting to NTFS will allow hard drives larger than 2 GB to be partitioned as one large drive.
1.4 Registering the Computer The computer should be registered with Compaq. Registration establishes a record of ownership and gives the user an opportunity to receive product announcements, updates, and other communications periodically. To register one machine, just visit Compaq’s Web site at www.compaq.com/products/registration and follow the instructions that appear on the screen.
chapter 2 SETUP UTILITIES AND DIAGNOSTIC FEATURES Compaq Computer Setup Utilities and diagnostic features provide information needed about the computer system when contacting Compaq Customer Support. These tools can also be used to: !" Change factory default settings and to set or change the system configuration, which may be necessary when you add or remove hardware. !" Determine if all of the devices installed on the computer are recognized by the system and functioning properly.
!" Select Post Messages Enabled or Disabled to change the display status of Power-On Self- Test (POST) messages. Post Messages Disabled suppresses most POST messages, such as memory count, product name, and other non-error text messages. If a POST error occurs, the error is displayed regardless of the mode selected. To manually switch to Post Messages Enabled during POST, press any key (except F10 or F12).
4. To apply and save changes, select File # Save Changes and Exit. ✎ ❏ If you selected an option that automatically restarted the computer, changes were applied at that time. ❏ If you have made changes that you do not want applied, select Ignore Changes and Exit. ❏ If you have already applied changes you now want to eliminate, select Set Defaults and Exit. This option will restore the original system defaults.
2.1.2 Computer Setup Menu Heading Option Description File System Information Lists product name, processor type/speed/stepping, cache size, system ROM family and version, installed memory size, system board revision, chassis serial number, integrated MAC for embedded, enabled NIC (if applicable), and asset tracking number.

Supports distributed computing environments (DCE) perspectives. !" Silent Setup Command Line Interface—Provides the functionality of the Graphical User Interface (GUI) in a silent command line interface and provides execution output in a log file.
chapter 3 DESKTOP MANAGEMENT Compaq pioneered intelligent manageability in 1995 with the introduction of the industry's first fully manageable desktop personal computers. Since then, Compaq has led an industry-wide effort to develop the standards and infrastructure required to effectively manage desktop PCs. Compaq Intelligent Manageability provides standards-based solutions for managing and controlling desktops in a networked environment.
3.1 Initial Configuration and Deployment Compaq computers come with a preinstalled system software image. After a very brief software “unbundling” process, the Compaq Deskpro Personal Computer or Workstation is ready to be used. You may prefer to replace the preinstalled software image with a customized set of system and application software. There are several methods for deploying a customized software image.
PC Transplant Pro and PC Transplant for Compaq PC Transplant, designed to assist you in personalizing the new Compaq computer, can be downloaded free from the Compaq Web site. It lets you preserve the “personality”—the customized settings such as Start menu entries, drive and printer mappings, software application options, and so on—of an existing PC, then transfer those unique settings to a Compaq PC so that you don’t have to invest valuable time manually recreating them.
The following table and sections refer to managing security features of your Computer locally through the Compaq Computer Setup Utilities. Refer to the Remote Management Setup Utilities for more information on using the Remote Security Management software. These utilities are available on the Support Software CD or from the Compaq Web site at www.compaq.com/support/files/index.html. For more information on Compaq Insight Manager LC, refer to www.compaq.com/im/lc.
3.2.1 Password Security This computer supports two security password features—a setup password and a power-on password. The power-on password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the power-on password.
Entering a Power-On Password 1. Turn on or restart the computer. If you are in Windows, click Start # Shut Down # Restart the Computer. 2. When the key icon appears on the monitor, enter your current password. ✎ Type carefully; for security reasons, the characters you type do not appear on the screen. If you enter the password incorrectly, a broken key icon appears. Try again. After three unsuccessful tries, you must turn off the computer, then turn it on again before you can continue.
National Keyboard Delimiter Characters Each keyboard is designed to meet country-specific requirements. The syntax and keys that you use for changing or deleting your password depend on the keyboard that came with your computer. / = / / ! é - Arabic Belgian BHCSY* Brazilian Chinese Czech Danish French French Canadian German . / / - Greek Hebrew Hungarian Italian Japanese Korean Latin American Norwegian Polish Portuguese / / / / .
3.2.3 Smart Cover Lock The Smart Cover Lock is a software-controllable cover lock featured on some desktop computers. This lock prevents unauthorized access to the internal components. Computers ship with the Smart Cover Lock in the unlocked position. CAUTION: For maximum cover lock security, be sure to establish a setup password. The setup password prevents unauthorized access to the Computer Setup utility. Locking the Smart Cover Lock 1. Turn on or restart the computer.
3.2.4 Master Boot Record Security The Master Boot Record (MBR) contains information needed to successfully boot from a disk and to access the data stored on the disk. Master Boot Record Security may prevent unintentional or malicious changes to the MBR, such as those caused by some computer viruses or by the incorrect use of certain disk utilities. It also allows you to recover the “last known good” MBR, should changes to the MBR be detected when the system is restarted.
In the unlikely event that the previously-saved MBR has been corrupted, the following message is displayed: 1998 - Master Boot Record has been lost. Press any key to enter Setup to configure MBR Security Upon entering Computer Setup, you must !" Save the MBR of the current bootable disk; or, !" Disable the MBR Security feature. You must know the setup password, if one exists.
3.3 Fault Notification and Recovery Fault Notification and Recovery 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 the Compaq Management Agent.
3.3.5 ECC Fault Prediction and Prefailure Warranty When the computer encounters an excessive number of error checking and correcting (ECC) memory errors, the computer 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.
these utilities to accomplish various remote management functions including ROM flash, changing security settings, and wakeup/shutdown. 3.4.1 Local ROM Flash To upgrade the ROM: 1. Insert the ROMPaq diskette in the diskette drive and turn on the computer. 2. If prompted, enter the Setup Password. ✎ If the Setup password is entered correctly, the ROMPaq utility will take over and run the ROM upgrade.
For more information on enabling Remote ROM Flash, refer to the online Remote Management Administrators Guide. The Remote Management Administrators Guide is included with the Remote Management Administration Tools, and is available on the Support Software CD or at the Compaq Web Site at www.compaq.com. 3.4.3 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 following table lists the various keyboard light combinations as well as the meaning and action associated with each combination. Num Lock Caps Lock Scroll Lock Meaning and Required Action OFF ON OFF System requires setup password. Enter the setup password. The light remains turned on until you enter a valid setup password. ON OFF OFF System could not start from diskette because the ROMPaq diskette is not present, is bad, or the drive is not ready.
3.4.4 Remote Security Management Remote Security Management allows the system administrator to safely set or modify security features on remote Compaq desktops, directly from the centralized network management console. Enabling the system administrator to perform these tasks remotely, on multiple computers, results in consistent deployment of and greater control over desktop security parameters over the network. It also results in greater productivity and lower total cost of ownership.
3.4.7 Replicating Original Setup This procedure gives an administrator the ability to easily copy one setup configuration to other computers of the same model. This allows for faster, more consistent configuration of multiple computers. To replicate the setup: 1. Access the Computer Setup Utilities menu. 2. Click File # Save to Floppy. Follow the instructions on the screen. ✎ This requires an internal diskette drive, a MultiBay LS-120 drive, or a portable, external diskette drive. 3.
3.4.9 Power Management Power Management is a feature that saves energy by shutting down certain components of the computer when they are not in use, saving energy without having to shut down the computer. Timeouts (the period of inactivity allowed before shutting down these components) can be enabled, customized, or disabled using Computer Setup. 1. Access the Computer Setup menu. 2. Select Power#Energy Saver. Select Advanced to turn on the Timeouts menu. 3. Select Power#Timeouts.
3.5 Building Blocks and Partners Compaq management solutions are based on industry standards, including DMI 2.0, Web-Based Enterprise Management, Intel's "Wired for Management" (WfM), SNMP, and Net PC technologies.

appendix B POWER CORD SET REQUIREMENTS The voltage select switch feature on the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. The power cord set received with the computer meets the requirements for use in the country where you purchased the equipment. Power cord sets for use in other countries must meet the requirements of the country where you use the computer.
Country-Specific Requirements Additional requirements specific to a country are shown in parentheses and explained below.
appendix C HARD DRIVES Device 0/Device 1 Relationship A device 0/device 1 relationship exists when there are two hard drives connected to a single port. In this situation, one drive must be designated as the device 0, and the other as the device 1 by the proper use of the drive jumpers. This designation is necessary because both drives cannot work simultaneously. When the computer supports cable-select, the device 0/device 1 designations are determined by each drive’s connector location on the data cable.
Drive Partition Size File System Operating System Maximum Partition Size FAT 16 DOS/Windows 95 2 GB FAT 16 Windows NT 4 GB FAT 32 2 Terabytes NTFS 2 Terabytes For example, an 8-GB drive operating in a Windows 95 environment using FAT 16 would have a total of four 2-GB drive partitions. That same drive operating in Windows NT using FAT 16 would have two 4-GB drive partitions unless the user elected to subdivide it into smaller sections.

A PCI or ISA card that has been installed is defective. Remove any expansion card that was just installed. 3. Reseat drive power, data, and power supply cables. 4. Disconnect all drive cables and reboot.
Solving Minor Problems Continued The Caps Lock LED is flashing; you may hear one long and two short beeps. The video controller is not present or is incorrectly initialized. Clear configuration memory (CMOS). If a video card has been added, remove and reseat it. Computer does not boot up and the Scroll Lock LED is flashing; you may hear two long and one short beeps. System board hardware failure (prior to video). Replace system board.
Diskette Drive Continued A problem has occurred with a disk transaction. The directory structure is bad, or there is a problem with a file. In Windows 95 or 98, run ScanDisk. Click Start # Programs # Accessories # System Tools # ScanDisk. In Windows NT, right click Start, click Explore, and select a drive. Select File # Properties # Tools. Under Error-checking, click Check Now. Non-system disk message. The system is trying to start from a nonsystem diskette. Remove the diskette from the drive.
Display Continued Characters are dim. 1. Adjust the monitor's brightness and contrast controls. 2. Check that the video cable is securely connected to the graphics card and monitor. 3. Set the RGB switch (and sync options, if available) to 75 ohms, with the sync set to External. Refer to the documentation included with the monitor. Monitor does not function properly when used with the energy saver features. Monitor without the energy saver feature is being used with energy saver features enabled.
Printer Problem Possible Solution Printer will not print. 1. Printer is not turned on and online. Turn the printer on and ensure it is online. 2. Run printer self-test. 3. Reseat both ends of the printer cable. 4. Verify that printer port is enabled in BIOS and in Windows using F10 Setup. 5. Try printing using the DOS command C:\ [printer port]. Where [printer port] is the port address to which the printer is connected. If printer works, problem is with the printer driver. Reload driver. 6.
Hard Drive The information provided by the diagnostics tests includes: error code, system serial number, drive serial number, drive model, and drive firmware revision. Specific details of the drive failure are not included. When you run the diagnostics, the test results are stored in a log. After completing the test, you can print this log to a local printer or save it to a file. Alternatively, before running the test, you can configure the test options to send the results to a local printer or file.
Hardware Installation You may need to reconfigure the computer when you add or remove hardware, such as an additional diskette drive. If you install a Plug and Play device, Windows 95 and 98 in most cases will automatically recognize the device and configures the computer. If a third-party Plug and Play device is not recognized, contact the device manufacturer. If you install a non-Plug and Play device, you must reconfigure the computer after completing installation of the new hardware.
DVD- and CD-ROM Problem Possible Solution Cannot read compact disc. 1. CD is not properly seated in the drive. Eject the CD, correctly seat it in the drive, then reload. 2. CD has been loaded upside down. Eject the CD, turn it over, then reload. System will not boot from CD-ROM or DVD drive. 1. The CD-ROM or DVD boot is not enabled through the Computer Setup utility. Run the Computer Setup utility and set the drive priorities. 2. Ensure that drive cabling and jumpers are set correctly.
Memory Problem Possible Solution System won't boot or does not function properly after installing additional memory modules Memory module is not the correct type or speed grade for the system. Replace module with the correct industry-standard device for the computer. Out of Memory error. 1. Memory configuration may not be set up correctly; check memory configuration using Device Manager. 2. The computer has run out of memory for the application.
Network Some common causes and solutions for network problems are listed in the following table. These guidelines do not discuss the process of debugging network cabling. Problem Possible Solution The Remote Wakeup feature is not functioning. 1. The feature is not available when using an AUI network connection; use an RJ-45 network connection. 2. Remote Wakeup is not enabled. Use the network control application to enable Remote Wakeup. Network driver does not detect network controller.
Network Problem Continued Problem Possible Solution Network controller stopped working when an expansion board was added to the computer. 1. Network drivers are not loaded or driver parameters do not match the current configuration. Make sure that the drivers are loaded and that the driver parameters match the configuration of the network controller. 2. The cable is not securely connected or is attached incorrectly.
Resolving Audio Hardware Conflicts Hardware conflicts occur when two or more peripheral devices contend for the same signal lines or channels. Conflicts between the audio interface and another peripheral device may be due to the settings of the base I/O addresses, interrupts, or DMA channels. The audio interface typically has the following settings: Item Setting Base I/O address 220H FM Synthesizer I/O address 388-38Bh Interrupt IRQ 5 8-bit DMA Channel 1 To resolve hardware conflicts: 1.
