Technology Codes

HP does not change the name of a product every time the product’s technology changes. While this helps ensure continuing market momentum for HP products, it complicates technology deployment and support processes.

To help solve this problem, HP has added a technology code to the serial number of each of its products. Since the BIOS must be matched to the notebook’s hardware, the same code is used for the BIOS and the hardware. This manual refers to technology code deferences where applicable.

The table below shows the technology codes and the changes they signify for the products. Before downloading software or drivers or performing repairs, note the technology code for the HP notebook model.

Note that the first two characters of the BIOS ID (for example, GC.M1.02) indicate the hardware technology. You can also determine the BIOS ID using the BIOS Setup Utility, or by pressing ESC during the boot process when the HP logo appears.

This manual contains service information for products having the following technology codes.

Troubleshooting

The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality repair, HP recommends that you follow the basic troubleshooting steps shown in the illustration below.

Check the customer’s description of the problem and any supporting information.

Try to duplicate the customer’s problem.

Troubleshoot the problem using

- Diagnostic tools.

- Troubleshooting suggestions.

Verify the repair by testing the functionality of the complete unit.

Figure 3-1. Basic Troubleshooting Steps

3-2 Troubleshooting and Diagnostics HP OmniBook XE3

Troubleshooting the Problem

Record pertinent information about the notebook:

• Model and serial number.

• Operating system and version.

• BIOS version.

• Accessories and peripherals used.

Analyze the problem:

Observe Symptoms. Using the customer’s information, try to duplicate the problem. Determine

•

how the problem differs from proper behavior. Also, take note of the functions that do work properly.

Separate Problems. If there is more than one symptom, separate them into distinct problems.

•

Consider Causes. Keep in mind possible causes for each problem. Use the diagnostic tools and

troubleshooting suggestions to help find the possible causes.

 The DiagTools diagnostic program tests most of the notebook’s components using automatic

and interactive tests, and will be your primary troubleshooting tool. Other tools include the power-on self-test, DMI/TopTools (if installed), the BIOS Setup utility, and the Sycard PCCtest. The table on page 3-4 shows how you can use these tools to isolate the cause of the notebook’s problem.

 The troubleshooting suggestions on page 3-5 include general suggestions for repairing units

that show specific failure symptoms.

Swapping modules that may be defective with others known to be good is generally an ideal way to find the module responsible for the problem. A failure symptom is rarely caused by more than one module, so you will not usually need to replace more than one module to correct a particular failure.

After you replace a module, the notebook will normally be in a confused state and lock up when you apply power. If this happens, press the system-off switch: this resets the notebook, so that you can restart it in a known state.

Verifying the Repair

Before returning the repaired notebook to the customer, verify the repair by running the following tests:

DiagTools Basic Diagnostic Test. Run the basic test of the DiagTools diagnostic program

•

(page 3-17).

–and–

Function Tests. Run tests that check the repaired function, such as in the DiagTools diagnostic

•

program (page 3-17).

–and–

Failed Tests. Run any other tests that failed during troubleshooting.

3-6 Troubleshooting and Diagnostics HP OmniBook XE3

Symptom Call Center:

Suggestions

Battery has short operating time.

Battery indicator is inaccurate.

Display

Dark display, no light.

Turn down display brightness.

Check Intel SpeedStep Technology settings in BIOS Setup Power menu. Try default setting.

Check settings in Power Management in Control Panel.

Certain applications can cause excess CPU and power usage. (User can get Intel Power Monitor from www.intel.com and monitor CPU load.)

When using applications with automatic save feature (such as MS Word), extend save time or disable to reduce hard disk access and power usage.

PCMCIA card use can affect battery life. Some PCMCIA cards draw power even while not in use.

Heavy modem use can affect battery operating time.

Time Remaining is an estimate based on how quickly the notebook is using power at that moment. It therefore depends on the current task, and assumes power will be used at the same rate until the battery runs out. So, for example, if the notebook is performing a task requiring a good deal of power (such as reading from a CD-ROM or DVD), the value will probably show too little time remaining.

Make sure notebook is turned on.

3-16 Troubleshooting and Diagnostics HP OmniBook XE3

Diagnostic Tools

This section describes the following diagnostic tools you can use for troubleshooting and repairing the notebook:

• DiagTools diagnostic program (below).

• Power-on self-test (page 3-24).

• Sycard PCCtest 450 PC Card (page 3-27).

• Desktop Management Interface (page 3-28).

• BIOS Setup utility (page 3-30).

DiagTools Diagnostic Program

The DiagTools hardware diagnostic program (version 2.30G as of this writing) provides two levels of testing:

• Automated testing using a basic hardware test.

• Advanced testing using individual hardware tests.

Figure 3-2. DiagTools Screens — Basic and Advanced

The tests are designed to run after the system restarts, so that the notebook will be in a predictable state during the tests. The tests are non-destructive, and are intended to preserve the state of the notebook. The notebook restarts when you exit the program so drivers can be loaded.

Updating DiagTools

You can download the latest version of DiagTools from the HP Notebook web site (see page vii). Follow the instructions included with the new version.

HP OmniBook XE3 Troubleshooting and Diagnostics 3-17

Running DiagTools

1. Restart the notebook.

2. When the HP logo appears, press F10 to start the diagnostic test.

3. When the initial diagnostics screen appears, press F2 twice to continue.

4. When the hardware detection finishes, check the list of detected hardware. The following

information and devices should be listed if applicable:

Product name Serial number IDE drives

Processor type Cache memory Audio device BIOS version Main memory

Note

If a device is not detected or fails its test, it might be configured incorrectly in BIOS Setup (see page 3-30). You can confirm this by running BIOS Setup and checking the settings.

5. Run the basic test. Press F2 to start the basic hardware test.

If the basic test fails, you can press F6 and start a Wizard that runs a set of advanced tests for the failed component. Then generate a support ticket.

6. If you intend to exit without running the advanced tests, press F4 to save system and test

information in the Support Ticket log file. Then remove the floppy disk, if present, and press F3 to exit.

Run the advanced tests. Press F2 twice to open the advanced test screen.

8. Select and run the appropriate tests. Tests are not listed if no such hardware is detected. Press the

following keys to run tests:

ENTER Runs the highlighted test.

F5 or SPACE Marks/unmarks the highlighted test. F6 Marks/unmarks all tests in the current menu. F7 Marks/unmarks all tests in all menus. F10 Runs all marked tests.

(Press F9 for a list of all function keys.) If any test fails, the error code is displayed temporarily, and the error code description is logged.

If several errors occur, look for patterns that might indicate a common cause. See the table on page 3-20 for repair suggestions. Consider these suggestions in combination with other troubleshooting information.

3-18 Troubleshooting and Diagnostics HP OmniBook XE3

9. When you are finished, press ESC to exit the advanced tests.

10. Press F4 twice (from the advanced test screen) or three times (from the basic test screen) to save

system and test information in the Support Ticket log file. (You can save this to a floppy disk, or

to the notebook’s hard disk.) Press F7 to view the Support Ticket.

Exit. Press F3 twice to exit and restart the notebook.

Power-On Self-Test

Note

If Quiet Boot is enabled in BIOS Setup (the default setting), press ESC during boot to see POST messages.

The POST (Power-On Self-Test) is a series of initialization routines and diagnostic tests that the system BIOS runs when the notebook boots. The system BIOS will not boot the operating system if system memory, the CPU, DMA, or the interrupt controller fails the POST diagnostic tests. POST progress is indicated by a sequence of codes, and error messages are displayed if possible.

You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or firmware failure. First, confirm the failure by performing a “clean” boot:

• Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external

monitor, pointing device, and keyboard.

• Provide “clean” AC power—no auto adapter or unusual AC adapter configuration.

• Press the system-off switch to return the notebook to a known state.

If the notebook fails to boot with a clean boot, it requires repair. If an error message appears, confirm the problem using other diagnostic tools. Not all POST messages indicate a hardware, software, or

firmware failure—some messages are for information only. If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code

(see the following table). The beep code indicates the POST routine in which the terminal error occurred.

Desktop Management Interface (DMI)

The Desktop Management Interface (DMI) is basically a set of rules for accessing information about a personal computer. Using DMI, an application program can determine, for example, which hardware and software components are present in the computer, the operating system being used, and the number of accessory board slots available. Using the DMI interface, a local or remote application program can check which hardware and software components are installed on your notebook, and may be able to tell how well they are working or whether any needs replacing. All this information is stored in a special Management Information Format (MIF) file, installed on each computer as part of the DMI package.

Installing the DMI Package

The DMI package is included with your notebook, but must be properly installed before it can be used. Install the package as follows.

To install the DMI preloaded on the hard disk:

• In Windows, click Start, Programs, HP TopTools for Notebooks, Setup.

To install the DMI from the Recovery CD, or from floppy disks:

1. Insert the Recovery CD, into the CD-ROM/DVD drive, or insert disk #1 into the floppy drive.

2. Select and run the SETUP program from the dmi\disk1 directory on the CD (under \hp\Drivers),

or from floppy disk #1.

Contents of the DMI Package

The DMI software and associated documentation is supplied either preinstalled on the notebook’s hard disk drive or on the Recovery CD. The contents of the package are the same for both.

Since the information accessed by the DMI software is specific to each particular computer, it must be installed on each computer separately. The DMI package included with a notebook can therefore be used only with that notebook.

The DMI package includes the following software:

• A Microsoft Windows utility (SETUP.EXE) to install and initialize the DMI software.

• A Windows utility, HP TopTools. After DMI is installed, this utility can display information

about the notebook through the DMI.

• A Management Information Format (MIF) file. This file contains information about everything on

the notebook that can be controlled using DMI facilities, and is initialized during installation.

• A component code, identifying the version of MIF file to use for specific models of HP notebook

computers.

• Windows-compatible DMTF Service Layer software, which controls access to the DMI.

• A client agent. The HP Remote DMI Agent is a DMI application and also a network server-side

stream-based application. The Remote Agent is listening for Remote Application connection requests. If the main window of the Remote Agent is hidden, then no icon appears on the screen when it is running.

Using the DMI Interface

For a complete explanation of how to take full advantage of DMI, see the following documentation (provided with your notebook):

• A README.TXT file.

• A Windows online help file describing Hewlett-Packard’s implementation of DMI (group and

attribute definitions). Since not all models support all of Hewlett-Packard enhanced features, this document also describes any restrictions that apply.

Description of DMI

The Desktop Management Interface (DMI) is the result of the efforts of the Desktop Management Task Force (DMTF) founded in 1992 by a group of leading computer manufacturers—including Hewlett-Packard—to define a standard method of managing the physical and logical components of personal computers.

Hewlett-Packard has developed a number of extensions to DMI to allow it to manage the enhanced features of HP notebook computers, including passwords and tattooing (identifying a computer using a unique string of characters).

For full details of the structure of the MIF file (including an explanation of the fields of groups and attributes, and how to write an application program that accesses this information), access the DMTF FTP server ftp.dmtf.org or the DMTF web pages at the http://www.dmtf.org.

Uninstalling the DMI Package

1. Click Start, Programs, HP TopTools for Notebooks, Uninstall DMI.

2. Restart the notebook.

BIOS Setup Utility

The BIOS Setup utility provides access to basic configuration settings. It is independent of the operating system.

Running the BIOS Setup Utility

1. Close all applications, then click Start, Shut Down, Reboot. (If necessary, you can press

CTRL+ALT+DEL to reboot.)

2. When the HP logo appears, press F2 to enter the BIOS Setup utility.

3. The pointing devices are not active in BIOS Setup, so you will need to use the keyboard to

navigate:

• Press the LEFT and RIGHT arrow keys to move among menus.

• Press the UP and DOWN arrow keys to move among parameters in a menu.

• Press F5 or F6 to move through values for the current parameter, or press ENTER to change a

setting.

4. After you select the options you want, press F10 or use the Exit menu to exit BIOS Setup. If the settings cause a conflict between devices during reboot, the system prompts you to run

BIOS Setup again, and marks the conflicting settings.
