Service Manual Troubleshooting and Diagnostics 3-17 Diagnostic Tools This section describes the following diagnostic tools you can use for troubleshooting and repairing the notebook: • Notebook e-Diagtools diagnostic program (below). • Power-on self-test (page 3-18). • Sycard PCCtest 450 PC card (page 3-24). • Windows Management Instrumentation (page 3-25). • BIOS Setup utility (page 3-25). e-Diagtools Diagnostic Program The hardware diagnostic programs provide two levels of testing: • User-level testing using a basic hardware test. • Advanced testing using individual hardware tests. The tests are designed to run after the system reboots, 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 reboots when you exit the program so drivers can be loaded. Updating e-Diagtools You can download the latest version of e-Diagtools using e-Diagtools for Windows. Running e-Diagtools The following procedure describes how to run e-Diagtools. The individual steps might differ slightly for different versions of e-Diagtools. 1. Click Start > Turn Off Computer (or Shut Down), Restart. 2. When the HP logo appears, press F10 to start the diagnostic test. The first time you run the program, you are prompted to select the language for the program. 3. When the menu appears, press F2 to run e-Diagtools. 4. When the Configuration Description appears, check the list of detected hardware. 5. Run the basic test . Press F2 to start the basic hardware test. The results appear when the test is complete. 6. If you intend to exit without running the advanced tests, press F4 to view the Support Ticket. Press F3 to exit e-Diagtools. 7. Optional: run the advanced tests . Press F2 to open the advanced test screen. 8. Use the arrow keys and ENTER to select the test you want to run. Tests are listed only for detected hardware. 9. Press F2 to run the selected tests and add the results to the Support Ticket.
3-18 Troubleshooting and Diagnostics Service Manual 10. After each run, press F2 to return to the advanced test screen, or press F4 to view the Support Ticket. 11. Exit. Press F3 and then any key to exit and reboot. 12. Optional: open the Support Ticket. In Windows, click Start > All Programs (or Programs) > Hewlett-Packard > Notebook > HP e-Diagtools > e-Diagtools for Windows. 13. Click View to display the Support Ticket. 14. To add information about your problem, click Comments, type the information, and then click OK. To save or print the Support Ticket, click Save As or Print. To e-mail the Support Ticket to your support agent, click e-Mail. The first time you make an e-mail connection from this program, click Change Settings in the Connect window and enter the settings recommended by your support agent. e-Diagtools for Windows can also update the version of e-Diagtools on your notebook’s hard disk. In e-Diagtools for Windows, use the e-Diagtools menu. If you have trouble running e-Diagtools diagnostics from the hard disk, you can also run it from the Recovery CD or DVD . Boot from the CD or DVD and select the diagnostics option. Interpreting the Results The e-Diagtools diagnostic program returns test groups, error codes, and suggestions for repair and/or follow-up actions. The basic hardware test shows a recommended replacement part. To help interpret the results of the e-Diagtools tests, refer to the following: • e-Diagtools Support Ticket on page 3-18. • Replaceable Module Diagram on page 1-14 • Functional Structure Description on page 1-15 This combined information should enable you to determine which of the notebook’s components require service. Power-On Self-Test Note If Quiet Boot is enabled in BIOS Setup (the default setting), press Esc during boot to see POST messages. When the notebook boots, its system BIOS runs a series of initialization routines and diagnostic tests called POST (Power-On Self-Test). The BIOS will not boot the notebook’s operating system if the system memory, CPU, DMA, or interrupt controller fails the POST diagnostic tests. POST indicates progress by a sequence of codes; if an error occurs, the BIOS displays a message and/or issues a beep code. Note that not all POST messages indicate a failure in the notebook—some messages are for information only. You should not necessarily interpret the failure of one or more POST tests as a hardware, software, or firmware failure. If POST displays an error message or issues a beep code indicating an error, confirm the problem using other diagnostic tools.
Service Manual Troubleshooting and Diagnostics 3-19 First, confirm the failure by performing a “clean” boot, as described below. Note that if the notebook fails to restart with a clean boot, it requires repair. 1. Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external monitor, pointing device, and keyboard. 2. Provide “clean” AC power—no auto adapter or unusual AC adapter configuration. 3. Press the reset button to return the notebook to a known state. 4. Press the power button to start the notebook. If the BIOS detects a terminal error condition, it halts POST after issuing a beep code and/or displaying a message (see the following table). The beep code indicates the POST routine in which the terminal error occurred. Table 3-4.
