Diagnostic Tools
This section describes the following diagnostic tools you can use for troubleshooting and repairing the
Omnibook:
 · Omnibook e-Diagtools or Diagtools (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 3-29).
Overview of Diagnostic Tools
The hardware diagnostic programs provide two levels of testing:
 · User-level testing using a basic hardware test.
 · Advanced testing using individual hardware tests.
     
Figure 3-2. Diagnostic Screens — Basic and Advanced
The tests are designed to run after the system reboots, so that the computer will be in a predictable
state during the tests. The tests are non-destructive, and are intended to preserve the state of the
computer. The computer reboots when you exit the program so drivers can be loaded.
Updating e-Diagtools
You can download the latest version of e-Diagtools from the HP Notebook Web site (see page vi),
then follow the included instructions. 
						

							3-18 Troubleshooting and Diagnostics HP Omnibook 6000/6100
Running e-Diagtools
The following steps describe e-Diagtools. Diagtools steps may differ slightly.
 1. Restart the computer.
 2. When the HP logo appears, press F10 to start the diagnostic test.
 3. When the menu appears, press ENTER to run e-DiagTools.
 4. The first time you run the program, you are prompted to select the language for the program.
 5. Press F2 to proceed with the basic tests.
 You can also proceed directly to the advanced tests from this point by pressing CTRL-F9 (in
which case skip to step 10, below).
 6. When the Configuration Description appears, check the list of detected hardware.
 
Note
 
If a device is not detected or fails its test, it might be configured incorrectly in BIOS Setup. You
can confirm this by running BIOS Setup and checking the settings—see “BIOS Setup Utility” on
page 3-29.
 7. Run the basic test. Press F2 to start the basic hardware test.
 8. To exit without running the advanced tests, press F4 to view the Support Ticket. Press F3 to exit.
 9. Optional: Run the advanced tests. Press F2 to open the advanced test screen.
 10. Select and run the appropriate tests. Note that individual tests do not appear if the hardware they
test is not 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.
 If a test fails, the error code and description are logged, and the error code is displayed
temporarily. 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.
 11. Save the Support Ticket. Press T to update and display a Support Ticket containing system and
test information.
 12. When you are finished running tests, press ESC to exit the advanced tests.
 13. Optional: To save the Support Ticket to a floppy disk, press F7 then ALT+C.
 14. Exit.
 Press F3 and then any key to exit and reboot.
 15. Optional for e-Diagtools only: Open the Support Ticket. In Windows, click Start, Programs,
HP e-DiagTools, e-DiagTools for Windows.
 16. Click View to display the Support Ticket.
 17. To add information about the problem, click Comments and type the information, then click OK.
 To save or print the Support Ticket, click Save As or Print.
For Diagtools, to view or edit the support ticket, run c:\Dmi\Hputils\Hpsuppt.exe.
