  • Page 29: Power-On Self-Test

    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 self- test results are absolutely clear and repeatable, confirm the results with at least two other non- self-test troubleshooting tools.

  • Page 30: Display Codes

    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.

  • Page 32: Omnibook Diagnostics

    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.

  • Page 33: User Interface

    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 IR test on the OmniBook 5500.

  • Page 35: Loop Back Connectors

    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.

  • Page 36: Details On Individual Diagnostic Tests

    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.

  • Page 39: Full 2 Unit Ir Test - (Firtest.exe)

    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.

  • Page 41: Printer Port - (Lpt.com)

    Printer Port - (LPT.COM) 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.

  • Page 42: Floppy Disk - (Fdc.exe)

    Floppy Disk - (FDC.EXE) 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).
