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 3-19). 
• Sycard PCCtest 450 PC card (page 3-25). 
• Windows Management Instrumentation (page 3-26). 
• BIOS Setup utility (page 3-26). 
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.

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 3-19. 
• Replaceable Module Diagram on page 1-27 
• Functional Structure Description on page 1-28 
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. 
2. 
3. 
4. 
Remove all accessories, including SDRAM modules, port replicator, PC cards, printer, external 
monitor, pointing device, and keyboard. 
Provide “clean” AC power—no auto adapter or unusual AC adapter configuration. 
Press the reset button to return the notebook to a known state. 
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.

Sycard PCCtest 450/460 PC Card (Optional) 
The PCCtest 450 and 460 cards (version 1.05) from Sycard Technology are the only recommended 
diagnostic tools that test the functionality of the PCMCIA slots using a PCMCIA card. Each is a 
Type II PC card that works with test software to exercise PCMCIA functions. (For details, see the 
Sycard Technology Web site: http://www.sycard.com). 
The PCCtest product contains these components: 
• PCCtest 450 or 460 (revision 1.05) PC card. 
• PCCtest 450/460 software disk. (Software updates are available at the Sycard Technology 
Web site.) 
• Configuration headers (PC card/16-bit and CardBus/32-bit) that attach to the card. 
You will also need a CardBus extender card (such as the Sycard PCCextend 70) to avoid wear on the 
Sycard PCMCIA connector. 
Use the following tests to check the function of the notebook’s PCMCIA slots. See the Sycard 
documentation for details about running the tests.

Windows Management Instrumentation (WMI) 
The Windows Management Instrumentation is basically sets of rules for accessing information about a 
notebook. WMI allows an application to determine, for example, the operating system being used, 
which hardware and software components are in the notebook, and possibly whether any of the 
components need replacing. A local or remote application can use the WMI interface to check which 
hardware and software components are installed on your notebook, and might be able to tell how well 
they are working or if they need replacement. 
Installing the WMI Package 
The WMI package is either preinstalled on the notebook’s hard disk or\
 can be downloaded from 
http://www.hp.com/toptools (the contents are the same in both cases). The package must be properly 
installed before it can be used. 
To install the WMI preloaded on the hard disk:
