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 3-27).
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.

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.
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.

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:
 1. Start Windows, if it is not already running.
 2. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Setup.
Using WMI
For a complete description of how to use WMI, see the following documentation provided with the
notebook:
 • A README.TXT file: click Start, Programs, Hewlett-Packard, HP Toptools Agent, Read me.
 • A Windows online help file describing Hewlett-Packard’s implementation of WMI (group and
attribute definitions): click Start, Programs Hewlett-Packard, HP Toptools Agent, HP Toptools
Help.
Uninstalling the WMI Package
 1. Click Start, Programs (or All Programs), Hewlett-Packard, HP Toptools Agent, Uninstall WMI.
 2. Restart the notebook.
