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. 
						

							3-18 Troubleshooting and Diagnostics HP OmniBook XE3
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.
 7. 
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.

 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.
 11. 
Exit. Press F3 twice to exit and restart the notebook.
 12. 
Optional: Check the log. The log file contains a hardware summary and a list of all test results
and errors. Run C:\Dmi\Hpdiags\Hpsuppt.exe to retrieve the log file to this directory and open it
in Notepad.
Note that the serial and parallel port tests are more thorough if you connect a loop-back connector to
the port before running the test for that port. See the wiring diagrams below.
