LAN/Network    
General problems.  Check cables and 
connections.  
Try connecting computer to 
another network station (if 
applicable). 
Try connecting cable to 
another computer or network 
station. If green light next to 
LAN port does not light, LAN 
cable may not be connected 
to network or network may be 
down. 
Check settings in Device 
Manager. If network adapter 
is disabled, enable it. If 
conflict exists, try disabling 
another device. 
Check settings in Control 
Panel. 
For W indows 98, open 
Network in Control Panel and 
make sure correct clients and 
protocols are installed. 
Use networking 
troubleshooter in W indows 
Help. 
Make sure LAN cable is 
Category 3, 4, or 5 for

Diagnostic Tools 
This section describes the following diagnostic tools you can use for troubleshooting and repairing the 
notebook: 
• e-DiagTools diagnostic program (below). 
• Power-on self-test (page 3-29). 
• Sycard PCCtest 450 PC Card (page 3-32). 
• Desktop/Windows Management Interface (page 3-33). 
• BIOS Setup utility (page 3-34). 
e-DiagTools Diagnostic Program 
The e-DiagTools hardware diagnostic program provides two levels of testing: 
• Basic user-level hardware test. 
• Advanced individual hardware tests. 
      
Figure 3-2. e-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 e-DiagTools 
You can download the latest version of e-DiagTools from the HP Notebook web site (see page vi). 
Follow the instructions included with the new version.  
						

							3-24  Troubleshooting and Diagnostics  HP Omnibook XE3 (Technology Code GF) 
Running e-DiagTools 
1.  Restart the notebook. 
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 hardware detection finishes, 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 3-34. 
7. 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. 
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. 
  (Press F9 for a list of all function keys.) 
  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 
Table 3-3 on page 3-26 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 restart the notebook.

15. Optional: Open the Support Ticket. In Windows, click Start, Programs (or All 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. 
Note that the parallel port test is more thorough if you connect a loop-back connector to the port 
before running the test for that port. See the wiring diagram below.
