Part 2 Troubleshooting • • • • • Power-On Self-Test OmniBook Diagnostics Desktop Management Interface System Configuration Utility 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.
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.
Message Possible Cause sequence until you insert the key into the key lock and turn it. NO BOOTABLE FLOPPY DRIVE 0 INSTALLED No bootable floppy drive was detected. Possible solutions: 1) Power down the system and check all appropriate connections, cables, etc. 2) In configurations where no floppy drive is installed, run System Configuration Utility and make sure the diskette drive configuration item is set to "None". 3) Replace the diskette drive if necessary.
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.
tests also read the keyboard and discard unexpected key presses, this feature may not work as 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.
Keys are accepted from the keyboard, an external keyboard, or the serial port. The Alt key, used in conjunction with the appropriate letter, will pop-up each menu on the screen. Refer to Table 6 for a description of each key that is available for use in the user interface. Table 6 - Dianostic Interface Available Keystrokes Space Description run the selected tests (marked or hightlighted) run the alternate selected tests (marked or highlighted). See list of individual tests.
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.
CPU - (CPU.EXE) The CPU test checks the general purpose registers by copying a bit pattern through each register. Then a test of the Translation Lookaside Buffer is performed. DOS Parameter none Explanation Valid Keystrokes n/a Action The CPU test ignores the keyboard. Failure Message User Aborted Failed Failed Error Code 1 2 3 Failed 4 Meaning User aborted test. The register test failed. The CPU is in protected mode, must clean boot. The Translate Lookaside Buffer test failed. RAM - (RAM.
Valid Keystrokes n/a Action The ROM test ignores the keyboard. Failure Message User Aborted Error Code 1 Meaning User aborted test. PCMCIA - (PCMCIA.COM) The PCMCIA test sets up the TI CardBus controller chip, tests IRQ 3, and restores the chip. DOS Parameter 0 1 (or any non-0 value) Explanation Test lower slot Test upper slot Valid Keystrokes n/a Action The PCMCIA test ignores the keyboard. Failure Message User Aborted Failed Error Code 1 2 Meaning User aborted test.
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.
the 3 speeds under test. Default = 3. 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 Phytest Valid Keystrokes any key Action Any keystroke will abort The Full 2 Unit IR test. Failure Message OK Must clean boot Explanation The test passed. A clean boot is required prior to the test (see step 1 above). The test was aborted. The test cannot run when the OmniBook is docked.
Printer Port - (LPT.COM) NOTE: This test requires a parallel loopback connector to be connected to the parallel port. The Printer Port test checks the data port by writing and reading different bytes 1000 times. The loopback connector is tested by toggling data bits 0 and 1 and seeing if the PE bit gets set. Finally, all of the loopback connections are tested. DOS Parameter none Explanation Valid Keystrokes n/a Action The Printer Port test ignores the keyboard.
Floppy Disk - (FDC.EXE) NOTE: This test requires a formatted floppy disk to be inserted in the floppy drive. The Floppy Disk test checks for the presence of a floppy drive with a floppy disk. If a floppy disk is not present in the drive, the test will prompt for one. At this point, a floppy disk must be inserted to continue (a reboot is necessary to abort at this stage). The sectors on the floppy disk are then tested. A complete test (100% of the sectors) takes about 1 minute and 38 seconds.
Valid Keystrokes n/a Action The Audio test ignores the keyboard. Failure Message User Aborted Failed Error Code 1 3 Meaning User aborted test. A sound chip configuration call failed Microphone - (MIKE.EXE) Within the user interface of DIAG, the Microphone test records for a short time and then plays back what was recorded (similar to the “Rec” parameter).
Valid Keystrokes Esc Action The Esc key will abort the Joystick test; all other keys are flushed. Failure Message User Aborted Error Code 1 Failed 2 Meaning Pointer movement test aborted with Esc Joystick button test aborted with Esc Icon LCD - (ICON.EXE) The Icon test illuminates each segment of the icons in the icon LCD, moving from left to right. The test then flashes the entire panel three times. This is a visual test; no error codes are returned.
DOS Parameter 1 any non-1 value Explanation Perform the short test Perform the full test Valid Keystrokes any key Action To abort the keyboard test, press five, consecutive, incorrect keys. Failure Message User Aborted Error Code 1 Meaning User aborted test. Pointing Device - (MOUSE.EXE) The Pointing Device test prompts the tester to move the mouse cursor to four points on the display. The left and right mouse buttons are then tested.
other keys flushed. Failure Message User Aborted CD Not Ready H/W Error Drive Not Present Read Error Error Code 1 2 3 4 5 Meaning User aborted test. CD not ready, no CD in drive Timeout waiting for IRQ CD drive not installed The read failed SCSI - (SCSI.EXE) NOTE: The OmniBook must be docked for this test to function properly. The SCSI test checks for the presence of the PCI BIOS and SCSI controller. The test then checks for the presence of a SCSI hard disk, resets it, and copies the file SCSI.
Failure Message User Aborted 44 Error Code 1 Meaning User aborted 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.
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.
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).
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.
System Menu The system menu of the SCU provides an interface to modify several system settings. See Figure 13 for an example of the system menu. An explanation of each system setting and the corresponding options are provided in Table 8.

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.
Symptom Keyboard Keyboard errors — 2 characters on a keystroke instead of one Keyboard errors — no response from key(s) Keyboard doesn’t respond, audio slow, battery problems Unit Hangs or Won’t Boot up Won’t boot up & no display Unit hangs at Win95 screen during boot Unit locks up after 2-3 minutes Unit goes into suspend after “Bridge controller” message, won’t resume TrackPoint/Cursor Cursor pointer drifts slightly. Cursor pointer “flying” or drifting excessively.
Symptom Call Center • Send in for repair if still losing time. PCMCIA failure Slow audio and display Computer gets hot • Check device manager in Win95 for resource conflicts • Send in for repair • Send in for repair • It is normal for the computer to get warm/hot especially with 150 & 166 MHz MMX CPU and if charging the battery. Try using the fold down legs to raise the back of the machine to promote air flow. • On OB2000 and OB5700, ensure air vents are clear.
