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

Troubleshooting the Problem

Record pertinent information about the unit: 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. 3-2 Troubleshooting and Diagnostics HP OmniBook XE2, • Consider Causes. Keep in mind possible causes for each problem. Use the diagnostic tools and troubleshooting suggestions to help find possible causes. The OmniBook diagnostic program is the primary troubleshooting tool—it tests most components using automatic and interactive tests. The table on page 3-4 shows how you can use the different diagnostic tools to isolate the cause. The troubleshooting suggestions on page 3-5 include general suggestions for repairing units with certain failure symptoms. Swapping easily replaced modules with known-good modules is an ideal way to isolate the cause down to the module level. It is rare for more than one module to be responsible for one failure symptom. Therefore, replacement of more than one module for a particular symptom should be the exception rather than the normal expectation. After replacing a module, it is normal for the unit to be in a confused state and lock up when power is applied. If this occurs, press the system-off button to restart the computer in a known state.

Verifying the Repair

Before returning the repaired unit to the customer, verify the repair by running the following tests: • Basic Diagnostic Test. Run the basic test of the OmniBook diagnostic program (page 3-11). –and– • Function Tests. Run tests that check the repaired function, such as in the OmniBook diagnostic program (page 3-11). –and– • Failed Tests. Run any other tests that failed during troubleshooting.

Diagnostic Tools

This section describes the following diagnostic tools you can use for troubleshooting and repairing the OmniBook: • OmniBook hardware diagnostic program (below). • Power-on self-test (page 3-16). • Desktop Management Interface (page 3-20). • BIOS Setup utility (page 3-22).

OmniBook Diagnostic Program

The OmniBook hardware diagnostic program provides two levels of testing: • User-level testing using the basic hardware test. • Advanced testing using the individual hardware tests. Figure 3-2. OmniBook Diagnostic Screens, Basic and Advanced The tests are designed to run after the system reboots. This ensures that the computer will be in a predictable state, so the diagnostic program can properly test the hardware components. The tests are non-destructive and are intended to preserve the state of the computer. The OmniBook reboots when you exit the program so drivers can be loaded. Creating a Diagnostic Floppy Disk After inserting a formatted floppy disk in the floppy drive, do one of the following to create a diagnostic floppy disk: • On an OmniBook with a factory software installation, run diaginst from the \Dmi\Hpdiags directory on the hard disk. –or– If TopTools is installed, use the DiagTools page to create the disk. • On any computer with a CD-ROM drive, run diaginst from the \Omnibook\Drivers\Hputils directory on the OmniBook Recovery CD. HP OmniBook XE2 Troubleshooting and Diagnostics 3-11, • On any computer with World Wide Web access, download the diagnostic software package from the OmniBook website (see page vi), run this file to unpack the files, then run diaginst to create the diagnostic disk. Running the Diagnostic Test 1. Insert the diagnostic disk in the floppy drive—or press F10 in the next step. 2. Reboot the OmniBook. 3. Go through the first several screens. 4. When the hardware detection finishes, check the list of detected hardware. The following information and devices should be listed if applicable: Product name Cache memory Graphics adapter Processor type Main memory Serial ports BIOS version IDE drives Parallel port Serial number Audio device Note If a device is not detected or fails its test below, it may be configured incorrectly in the BIOS Setup utility (page 3-22). You can confirm the problem by running BIOS Setup and checking the settings. 5. Run the basic test. Press F2 to start the basic hardware test. 6. If you intend to exit without running advanced tests, press F4 to save system and test information in the Support Ticket log file, HPSUPPT.TXT. Then remove the diagnostic disk and press F3 to exit. 7. Run the advanced tests. Press F2 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 or unmarks the highlighted test. F6 Marks or unmarks all tests in the current menu. F7 Marks or unmarks all tests in all menus. F10 Runs all marked tests. If any test fails, the error is logged (error code and description) and displayed temporarily (error code). If several errors occur, look for patterns that might indicate a common cause. See the table on page 3-13 for repair suggestions. Consider these suggestions in combination with other troubleshooting information. 9. When you are finished running tests, press ESC to exit the advanced tests. 10. Press F4 to save system and test information in the Support Ticket log file, HPSUPPT.TXT. 11. Exit. Press F3 to exit and reboot. 12. Optional: Check the log. On any computer, open the HPSUPPT.TXT log file on the diagnostic disk using Notepad or other text editor. It contains a hardware summary and a list of all test results and errors. 3-12 Troubleshooting and Diagnostics HP OmniBook XE2,

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 computer 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. If possible, error messages are displayed. You should not interpret the failure of one or more POST tests as a hardware, software, or firmware failure. First, confirm the failure with a “clean” boot: • Remove all accessories, including RAM boards, floppy drive, 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 button to start from a known state. If the computer fails to boot with a clean boot, it requires repair. If an error message is displayed, confirm the problem using other diagnostic tools. Not all POST messages indicate a hardware, software, or firmware failure—some messages are informational messages. If the BIOS detects a terminal error condition, it halts POST after issuing a terminal error beep code— up to four groups of 1 to 4 short beeps. The beep code indicates the POST routine in which the terminal error occurred. The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (no card installed or faulty) or if an external ROM module does not properly checksum to zero. 3-16 Troubleshooting and Diagnostics HP OmniBook XE2,

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 a personal computer, the operating system that is being used, and the number of accessory board slots that are available. Using the DMI interface, a local or remote application program can check what hardware and software components are installed on your computer, 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 personal computer as part of the DMI package. Installing the DMI Package The DMI package is included with the OmniBook, but it must be properly installed before it can be used. The following steps explain how. To install the DMI preloaded on the hard disk: 1. Start Windows, if it is not already running. 2. Click Start, Programs, HP DMI, Setup. To install the DMI from the OmniBook Recovery CD or from floppy disks: 1. If you do not have a CD-ROM drive, create installation floppy disks • On any computer with a CD-ROM drive, copy the DMI software from the dmi directory of the Recovery CD (under \omnibook\drivers) to two or more floppy disks (for example, copy the contents of the \disk1 subdirectory to disk #1). • On any computer with World Wide Web access, download the Top Tools package from the OmniBook website (see page vi), then create the floppy disks as directed. 2. Start Windows, if it is not already running. 3. Insert the Recovery CD into the CD-ROM drive, or insert disk #1 into the floppy drive. 4. Select and run the SETUP program from the dmi\disk1 directory on the CD (under \omnibook\drivers), or from floppy disk #1. Uninstalling the DMI Package 1. Click Start, Programs, HP DMI, Uninstall DMI. 2. Reboot the PC. Using the DMI Interface For a complete explanation of how to fully take advantage of DMI, the following documentation is provided with the OmniBook: • A README.TXT file. • A Windows online help file describing Hewlett-Packard’s implementation of DMI (group and attribute definitions). Since not all Hewlett-Packard enhanced features are supported on all models, 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). This task force was founded in 1992 by a group of leading computer 3-20 Troubleshooting and Diagnostics HP OmniBook XE2, 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 the enhanced features of HP OmniBook computer to be managed with DMI, including features such as 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 meaning of the fields of groups and attributes and how to write an application program that accesses this information, you can access the DMTF FTP server ftp.dmtf.org or the DMTF web pages at the http://www.dmtf.org. Contents of the DMI Package The DMI software and associated documentation is supplied either preinstalled on the OmniBook’s hard disk drive or on two floppy disks. The contents of the package are the same in both cases. Since the information accessed by the DMI software is specific to a particular computer, it must be installed on each computer separately. The DMI package included with the OmniBook can be used only with the OmniBook. The following software is supplied with the DMI package: • 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 be used to display information about the computer through the DMI. • A Management Information Format (MIF) file. This file contains information about everything on the computer 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 OmniBook 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 will appear on the screen when it is running. HP OmniBook XE2 Troubleshooting and Diagnostics 3-21,

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 shut down Windows and reboot the OmniBook. If necessary, you can press CTRL+ALT+DEL to reboot. 2. During reboot, press F2 to start the BIOS Setup utility. 3. The pointing device or mouse is not active in the BIOS Setup utility. Press the RIGHT and LEFT arrow keys to move among menus. Press the DOWN and UP arrow keys to move among parameters in a menu. Press ENTER to change a setting. See the table below for more information. 4. After you select the options you want, press F10 or use the Exit menu to exit the BIOS Setup utility.

Password removal policy. • Display quality statement. • Technology Codes.

Password Removal Policy

If the user forgets the system password, the user calls Technical Support to determine the proper removal procedure. The user must provide proof of ownership, and the OmniBook must be operated during the procedure. The password removal procedure is protected as HP Company Private information. There are a restricted number of locations that can perform password removal. It may not be disclosed or distributed outside those locations. Password removal is strictly controlled. Hewlett-Packard and authorized support providers must ensure with written evidence that the OmniBook being “cleansed” is actually in the possession of the unit’s actual and current owner. This requires a sales receipt showing the unit serial number and owner’s name, or a written statement from the owner attesting that he or she is the owner of the unit. The statement can be a fax copy of the document. The fact that the unit is in the hands of an HP representative on behalf of the customer is not evidence of ownership. In addition, HP will not remove the password of a unit for any non-owner, even if it is requested by law enforcement agencies. If you receive such a request, you should notify management and HP Corporate Legal immediately. (These requests may require a court order prior to our participation.) Further, the entity removing the password must log the name, serial number and date of the removal, and file the written backup with the log. The log and backup are subject to standard record retention process and review. The final issue relating to removal of passwords is that HP cannot provide information to users that would assist them in improperly removing a password and opening a unit.,

Hewlett-Packard Display Quality Statement

TFT display manufacturing is a high precision but imperfect technology, and manufacturers cannot currently produce large displays that are cosmetically perfect. Most, if not all, TFT displays will exhibit some level of cosmetic imperfection. These cosmetic imperfections may be visible to the customer under varying display conditions and can appear as bright, dim, or dark spots. This issue is common across all vendors supplying TFT displays in their products and is not specific to the HP OmniBook display. HP OmniBook TFT displays meet or exceed all TFT manufacturer’s standards for cosmetic quality of TFT displays. HP does not warrant that the displays will be free of cosmetic imperfections. TFT displays may have a small number of cosmetic imperfections and still conform to the display manufacturer’s cosmetic quality specifications. Here are some guidelines to use in determining what action to take on customers’ complaints of cosmetic imperfections in their TFT displays: 1. The unit should be viewed in the customer’s normal operating condition. This means if the customer uses the unit predominately in DOS, in Windows, or in some other application or combination of applications, that is where you should make the determination. Self test is not a normal operating condition and is not a sufficient tool to interpret display quality. 2. Use the table below to determine whether the display should be considered for replacement. These are the only conditions in this guideline that may call for a replacement due to a defect in material or workmanship based on the HP Limited Warranty Statement. 3. If a display is considered for replacement, it should be clear to the customer that cosmetic variations on the replacement display may also exist, and may require the customer to use a work- around to obscure the cosmetic imperfection. 4. Customers with cosmetic-based complaints only, that do not conform to the above conditions and tests, will not normally be considered for display replacement. It will be left to the judgment of the HP-responsible person working with the customer, to identify work-arounds that are reasonable and appropriate for the individual customer. Customers who must have a more perfect display solution should consider switching to an OmniBook with a DSTN display. We expect over time that the industry will continue to improve in its ability to produce displays with fewer inherent cosmetic imperfections, and we will adjust our HP guidelines as the improvements are implemented. Table 5-1. OmniBook XE LCD Guidelines (TFT) Type of Imperfection Imperfections Not Allowed 13.3" TFT, SVGA Electrical Imperfections: • 7 or more single bright dots.

Caused by foreign circular matter on the backlight. c Line: A line on the display that appears dark or light and does not change in size. Caused by contamination (lint, hair) behind the display. d Polarizer scratch: A light line that is visible on a darker background and does not change in size. e Polarizer dent or bubble: A light spot with a darker border that appears on a lighted display and does not change in size.,

OmniBook XE Technology Codes

HP does not change the product name every time the product technology changes. While this helps ensure continuing market momentum for the products, it complicates the technology deployment and support processes. To help with these processes, HP has chosen to add a technology code (sometimes also referred to as sub-branding") to the serial number label. The chart below, shows the technology codes and the changes they signify for the Products based on the Omnibook XE2 technology. Since the BIOS needs to be matched to the hardware in the system, the team has chosen to use the same code to indicate the BIOS technology and the hardware technology. Note that systems produced before the Omnibook XE2-DD technology will NOT have this code printed on the serial number label, but the first two characters of the BIOS ID (e.g. DB.M1.04) still gives an indication of the hardware technology. Product Technology Product Details Name Code Number(s) OmniBook DB F1756W, F1755W Same motherboard as Typhoon XE2 F1779D 1 - increase BIOS chip to 512K for ACPI BIOS DD F1962W, F1774W New motherboard - design F1775W based on micro PGA-1 - F1671N, F1672W derived from Typhoon-2.x F1673W design
