• Troubleshooting Tips
Power-On Self-Test
The OmniBook 2000, 5500, and 5700 BIOS includes a Power-On Self-Test (POST) facility that
tests a number of hardware and firmware items in the unit at each cold-start (BOOT or RESET).
The OmniBook self-test alone should not be used to diagnose a hardware problem. If the selftest results are absolutely clear and repeatable, confirm the results with at least two other nonself-test troubleshooting tools.
Within POST, there are three kinds of messages:
• Error Messages – These messages appear when there is a failure in hardware,
software, or firmware.
• Informational Messages – These messages provide information to the user but
require no action.
• Beep Codes – This kind of warning sounds when POST errors occur and the screen
is not yet available.
Beep Codes
These multiple beep codes indicate a failure in a simple test of:
• a portion of base memory
• flash BIOS checksum
• a portion of conventional memory
• a portion of extended memory
If the unit fails to boot
• all accessories are removed, including:
memory, floppy drive, docking station, modems and other PC Cards, printers,
external displays, pointing devices, and keyboard
• clean AC power is provided (no "chained" battery chargers or auto adapters), and
press reset.
If the unit still fails to boot, it requires service.
Beep codes are used to identify a POST error that occurs when the screen is not available.
Once the screen is operating, diagnostic messages are reported to the screen. There are beep
codes for both fatal and nonfatal system board errors.
Table 4 - POST Beep Codes
Beep Code Description
S-S-S-P-S-S-L-P The DMA page registers are faulty.
S-S-S-P-S-L-S-P The refresh circuitry is faulty
S-S-S-P-S-L-L-P The ROM checksum is incorrect
S-S-S-P-L-S-S-P The CMOS RAM test failed
S-S-S-P-L-S-L-P The DMA controller is faulty

S-S-L-P-S-S-S-P No video adapter was found
S-S-L-P-S-S-L-P No RAM installed. No message is displayed.
26
Display Codes
There are a number of Power On Self Test (POST) tests that are performed after the Beep Code
tests. Failure of one or more of these tests will result in a displayed failure code (such as
03044). It is extremely important not to interpret a failure code immediately as a hardware
failure. The failure should be confirmed with a clean boot. A clean boot is defined as pressing
the reset button after removing all accessories (including memory, floppy drive, modems, PC
cards, and printers) and providing a reliable power source. Note, make sure the display is
adjusted to be visible.

OmniBook Diagnostics
The OmniBook diagnostics program provides a tool for diagnosing and isolating a hardware
problem. The diagnostics software is intended for use in concert with additional troubleshooting
methods to accurately determine the cause of trouble. The diagnostics program is not designed
for unassisted customer use. Unless otherwise indicated, all diagnostic tests and features are
available on the OmniBook 2000, 5500, and 5700.
All tests provided in the diagnostics program are designed to run following a clean boot of the
OmniBook. This ensures that the environment of the computer will be In a dependable state for
the diagnostics program to properly test the hardware components. The individual tests are nondestructive and are intended to preserve the state of the OmniBook. Reboot after completion of
any test to ensure proper loading of necessary drivers.
Running diagnostics
The diagnostic software must be executed from a DOS command-line following a clean boot.
For a system that normally boots to Windows for Workgroups, press F5 at bootup after the BIOS
displays the CPU speed. This will boot the OmniBook to a DOS command-line. For a Windows
95 system, press Shift-F5. The user interface may be invoked or individual tests can be initiated
from the command-line. When executed from the command-line, a test may or may not display
results, but always terminates with either a zero for success or a non-zero for failure (the DOS
errorlevel will be set accordingly). Non-zero results can be unique for each test (a result of 2
from a RAM test has a different meaning than a 2 from the serial test).
The diagnostic program is located in the c:\omnibook\diag directory. The main diagnostic
program (user interface) is invoked by typing diag at the command-line. The main program
looks for executables to perform individual tests using the same path with which it was invoked.
For example, if the program was initiated by typing c:\omnibook\diag\diag from the root
directory, then the diag directory will be searched for individual test programs.
Logging Test Results
Results can be logged to a file in the current drive and directory by pressing Alt-L. Only failures
are written to the file. The log file is in ASCII format with the following layout:
date time test label failure description
The main program performs the logging. When logging is enabled for the first time (via the
keyboard), the specified file is opened. If the file already exists, it is truncated. When logging is
disabled or the program is terminated, the file is closed.
Looping Tests
Any test, or selection of tests, can be made to repeat or loop. The loop count can be changed by
pressing Alt-C. The default count is 1; the maximum count is 9,999. A count of zero (0)
indicates infinite looping. The count that is set applies to all tests until DIAG is terminated or the
count is changed again.
Pressing the Backspace key will abort the looping sequence. The diagnostics program will check
the keyboard for the Backspace key between each test and each iteration. However, since many
29
tests also read the keyboard and discard unexpected key presses, this feature may not work as
Version mm/dd/yy
Press ESC to exit
expected.
When looping is enabled (count 0 or greater than 1), the date and time is displayed as each test
is executed. The timestamp is displayed as the test begins and is over-written at completion.
The DIAG.INI file, located in the c:\omnibook\diag directory, contains a “Loop” entry for each
test. The value of the entry determines whether the test can be placed in looping mode as part
of a group of tests. A value of “1” enables looping in a group, while a ”0” disables this feature.
Regardless of this setting, looping will always be available when a test is initiated individually;
the Loop entry in DIAG.INI only affects looping on groups of test. In general, group looping is
disabled for the tests that require action by the tester such as the keyboard, mouse, and joystick
tests.
User Interface
The main diagnostic program provides a user interface where the following actions can be
performed:
• launch individual or groups of tests
• loop through a given set of tests n times or indefinitely
• optionally log failures to disk
An example of the user interface screen is displayed below. Note, on the OmniBook 5500, the
Full 2 Unit IR and Fan tests are not available. Also, the Internal IR test is referred to as the Fast

results are OK, Done, User Abort, Failed or a brief message indicating the type of failure. OK
indicates that the test passed. Done indicates that the test has completed. See Details on
Individual Diagnostic Tests beginning on page 33 for more information on each individual test.
Special test hardware requirements
Several tests within the OmniBook diagnostics program require special hardware. If the
hardware is not present, the diagnostics will fail or not function properly. The below table lists
the tests that require special hardware.

Loop Back Connectors
In order to run the RS232 serial port or parallel port self-test, a loop back connector is needed.
The loop back may be placed on either the OmniBook port or at the end of the corresponding
cable. This feature is also helpful in diagnosing a defective serial or parallel cable.
Loop back connectors may be purchased or easily constructed. The following illustrations
identify the correct pin-out configurations for the serial and parallel loop back connectors.

Details on Individual Diagnostic Tests
This section explains each test within the diagnostics program. Each test is listed along with its
command-line file name. A brief description of the test, command-line parameters, valid
keystrokes available during the test, and corresponding failure messages with error codes are
also given.
Note, the term “flushed” that is used in the keystrokes sections indicates that the key is read from
the key buffer and then discarded.
Test All
This is an easy way to run all the tests in sequence. However, looping does not work as
expected with the Test All selection. For example, if three tests are tagged for looping and Test
All is initiated, then the first two tests are executed only once. The last test in the sequence is
the only test that will be looped.
Display - (DISP.COM)
The Display test executes a sequence of patterns on the screen:
1. Tests video RAM, which leaves vertical lines in groups of 4.
2. Draws a box around the outside edge of the display, filling the center with black.
3. Fills the entire display with white.
4. Fills the entire display with a 10-pixel checkerboard.
5. Fills the display with horizontal lines on every 4th pixel, then steps the lines 3 times.
6. Fills the display with vertical lines on every 4th pixel, then steps the lines 3 times.
7. Draws 16 horizontal bars of different colors.
8. Draws 16 vertical bars of different colors.
9. Draws 4 horizontal shaded bands (red, green, blue, and white) with vertical tick marks.

Full 2 Unit IR Test - (FIRTEST.EXE)
The Full 2 Unit IR test is not available on the OmniBook 5500. This test requires two
OmniBooks: one on which the IR is known to be good, and the computer to be tested. The
computer that is being tested will transmit IR packets to the known good computer, which will
transmit (reflect) the packets back. This method ensures both transmitting and receiving
functions are checked on the computer under test.
The test checks 115200 baud, 1.152 Mbps, and 4 Mbps by sending 20 packets at each speed
and looping through the 3 speeds three times for a total of 60 packets at each speed. Every
received packet is checked byte for byte against the packet that was sent. Every packet must
pass or the test will fail.
To run the "Full 2 Unit IR" test, perform the following steps:
1. Clean boot both computers.
Windows 95 -- reboot and press <shift><F5> shortly before or after the
computer displays "Starting Windows 95".
Windows for Workgroups -- reboot and press <F5> while the boot menu
is displayed.
After clean booting, change to the c:\omnibook\diag directory.
2. Prepare the known good computer to reflect packets to the test unit.
Run DIAG.EXE and highlight "Full 2 Unit IR" and press
<CTRL> + <ENTER>. (When desired testing duration is
complete, press any key to abort the reflecting end of the test.)
3. Position the computer to be tested so that the IR port is in line with the IR port on the
known good unit. For a simple pass/fail test, run DIAG.EXE, highlight "Full 2 Unit IR"
and press <ENTER>.
DOS Parameter Explanation
Internal Performs the internal (standalone) loopback
test. This option does not test as much of
the IR hardware, but will work with just one
computer. Do not use this parameter with
any of the other parameters.
Reflect Initiates the "known good" reflecting end of
the full 2 unit test.
Baud=xxxxxx Sets the baud for the first speed tested
(defaults to 115200 baud). Unless
/PHYTEST is also used, the 1.152M and
4M speeds will always be tested. Type in
the full number for the baud to be tested
(type 1152000 for 1.152Mbps, 4000000 for
4Mbps). Note -- This parameter must be
used on both the known good reflecting
computer and the computer under test.
Both computers must start at the same
speed to be able to communicate.
Loops=xxxxx Sets the number of times to loop through
36
the 3 speeds under test. Default = 3.
Phytest Limits the test to just one speed which can
be set with /BAUD. It also uses all null
bytes rather than random data. Default
speed = 115200 baud
Valid Keystrokes Action
any key Any keystroke will abort The Full 2 Unit IR
test.
Failure Message Explanation
OK The test passed.
Must clean boot A clean boot is required prior to the test
(see step 1 above).
User abort The test was aborted.
Must undock The test cannot run when the OmniBook is
docked.
No reflector unit The computer under test did not receive
back any of the packets it transmitted.
Either the known good computer is not
positioned properly or is not running the test
(see step 2 above).
Fail The test failed.
RS-232 Port - (RS232.COM)
NOTE:
The RS-232 Port test reads/writes to the COM1 serial port IER, baud divisor registers, and LCR.
It also checks for the loopback connector and sends a byte through the loopback connector at
each of the baud rates. The RS-232 Port test is hardcoded to test the UART at 3F8, therefore, it
can test only COM1.
DOS Parameter Explanation

Keyboard - (KEYBD.EXE)
The Keyboard test consists of two types of tests: a full keyboard test, and a short keyboard test.
For the full test, press the keys from left to right, top to bottom starting with Esc. For the short
test, start with Pause/Break key and go clockwise around the outside of the keyboard and finish
at the Scroll Lock key. Both tests skip the Fn key.
A high-pitched beep after a key press means it was the correct key and a low-pitched beep
means it was incorrect. After an incorrect key is entered (low-pitched beep), the test allows four
more attempts at entering the correct key.
The “Display Mode” of the keyboard test will display the number of the key as each key is
pressed. The keys may be entered in any order. This mode is entered by pressing Esc during
the test (as long as Esc is not the next key in the key sequence to be tested). Pressing Esc
again exits display mode and resumes the keyboard test.

Desktop Management Interface (DMI)
The Desktop Management Task Force (DMTF) was 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. The result of these efforts is the
Desktop Management Interface (DMI). The DMI package is pre-installed on the OmniBook 2000
and 5700.
Description of DMI
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,
how well they are working, and 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. The MIF file specifies information about
components at two levels:
• Groups contain all the information concerning a particular hardware or software
component. If more than one component of the same type is present, as is often the
case with serial ports and hard disk drives, a group is repeated.
• Attributes are specific items of information relating to a group. Attributes of the Mouse
group, for example, include the number of mouse buttons and the name and version
number of the mouse driver being used.
Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced features
of HP OmniBook Notebook PCs to be managed with DMI. These extensions cover:
• Administrator and user passwords.
• Tattooing: a string of characters that uniquely identifies the computer.
Note: The DMI software package included with the OmniBook can only be used with the HP
OmniBook Notebook PC.
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
URL www.dmtf.org .
Contents of the DMI Package
The DMI software and associated documentation is supplied either pre-installed on the
OmniBook's hard disk drive or on two flexible 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.

• 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 Notebook PCs.
• 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.
Figure 11 provides a visual representation of the many components of the DMI package.
Figure 11 - DMI Components
46
Installing the DMI Package from Windows 95
The DMI package is included with the OmniBook, but it must be properly installed before it can
be used. The following steps explain how.
Alternatively, to install the DMI from floppy disks:
• Copy the DMI software from the \omnibook\dirvers\win95\dmi directory of either the hard
disk or Recovery CD to two floppy diskettes (copy the contents of the \disk1 subdirectory to
diskette #1 and the contents of the \disk2 subdirectory to diskette #2).
• Start Windows 95, if it is not already running.
• Insert diskette #1 into the floppy drive.
• Select and run the SETUP program from the diskette #1.
To install the DMI preloaded on the hard disk:
• Start Windows 95, if it is not already running.
• Click on "Start".
• Go to "Programs - HP DMI".
• Select and run "SETUP".
Uninstalling the DMI Package from Windows 95
• Go to the HP DMI group.
• Launch the program "Uninstall DMI".
• 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.

System Configuration Utility
The System Configuration Utility (SCU) can be used to troubleshoot both software and hardware
issues. Settings in the SCU may cause unexpected results in the operation of the OmniBook or
installed applications. Battery charge and other system settings also can be verified with the
SCU. The SCU settings are identical for the OmniBook 2000, 5500, and 5700, except where
noted below.
The SCU is operating system independent and can be accessed by pressing F2 at boot-up or
Fn+F2 at any other time. Use the <Alt> key to activate the menus and the cursor keys to
navigate. The left mouse button, spacebar, and <Enter> key can also be used. The right mouse
button and the <Esc> key will cancel the current action.
Main Configuration Screen
The main configuration screen of the SCU reports several system settings. See Figure 12 for an
example of the main screen. The reported settings cannot be modified from the main screen;
the changes must be made from the corresponding menu.

Troubleshooting Tips
Presented below is a table showing general guidelines for repairing units with specific failure
symptoms. The order of likely causes is based upon data gathered by HP from analysis of failed
modules. The suggested order of investigation is not mandatory but reflects the priority HP
would currently place on looking for the root cause.
Swapping of easily replaced modules with known good reference modules is the ideal way to
isolate the cause down to the module level. It is rare for more than one module to be
responsible for the same failure symptom. Therefore, replacement of more than one module for
a particular symptom should be the exception rather than the normal expectation.
After replacing modules, it is normal for some units to end up in a confused state and lock up
when ac power is applied. If this occurs, the reset button should be pressed to bring the
computer to a known state. If the unit still locks up or continues to lock up each time ac power is
applied, the unit needs additional analysis.

Logic PCA Board (PCA PB-586/IO Bracket)
(HP Authorized Service Providers Only)
The OmniBook 2000 and 5700 are shipped with an electronic serial number programmed in
EEPROM on the Logic PCA Board. This built-in serial number will help MIS managers in
tracking assets and software configuration. Serial numbers can also be used for security and in
tracking lost or stolen notebooks. The Desktop Management Interface (DMI) TopTools
application shipped with the OmniBook can be used to read the serial number locally and across
a network (requires HP OpenView network administration software architecture).
Programming the Electronic Serial Number
All replacement Logic PCA Boards will arrive without a serial number programmed in EEPROM.
The following procedure provides the steps necessary to program the electronic serial number
1. After installation of the replacement Logic PCA Board and upon reboot, the OmniBook will
halt with this prompt:
INVALID ELECTRONIC SERIAL NUMBER
PRESS ANY KEY TO CONTINUE
2. After a key is pressed, the OmniBook will continue a normal boot process. The HP
Authorized Service Provider must program a valid serial number before the OmniBook can
be shipped to the customer.
3. Boot the OmniBook to the DOS command-line an run the ESN.EXE program located in the
c:\omnibook\diag directory.
4. The ESN program will prompt for a valid serial number.
5. Enter the serial number located on the bottom of the OmniBook. Use uppercase letters to be
consistent with the appearance of the serial number on the OmniBook. The ESN program
will burn the serial number into EEPROM.
Overriding an Incorrect Electronic Serial Number
If an incorrect serial number is inadvertently burned into EEPROM, it can be corrected. Perform
the following steps:
1. Run the ESN.EXE program located in the c:\omnibook\diag directory.
2. The ESN program will prompt to confirm that the serial number is incorrect. It will then
generate a five (5) digit number key.
3. The HP Authorized Service Provider must contact Hewlett-Packard Technical Support at this
point.
4. HP Technical Support will ask for a CZ authorization number, or comparable credentials, and
the five (5) digit number (from step 2).
5. HP Technical Support will provide a validation key to the HP Authorized Service Provider.
6. Enter the validation key. This will erase the existing electronic serial number and prompt for
a new number.
7. Follow the above steps in Programming the Electronic Serial Number to enter the correct
serial number.
Note, updating the BIOS or software on the OmniBook will not affect the electronic serial
number.
