							Self-troubleshooting with HP Vision Field Diagnostics
Hewlett-Packard Vision Field Diagnostics is a diagnostic tool that can be used by the end user or
technical support personnel to view information about the hardware configuration of the computer and
perform hardware troubleshooting on HP Desktop and Workstation systems. This diagnostic tool should
be used to help determine hardware failures. Accessible by either CD or USB key, these diagnostics
run outside the operating system and so make it easy to isolate potential issues that may be operating
system related versus hardware.
HP Vision Field Diagnostics benefits are:
●Capture complete system configuration information that can be shared as an HTML file, including:
◦System serial number
◦System product number
◦System BIOS revision
◦Memory size and configuration
◦Processor information
◦Storage device information and configuration
◦Graphics / audio / communications information and configuration
◦And more...
●Comprehensive list of diagnostic test available with new added features:
◦Highly configurable testing options: quick / complete / custom / interactive / non-interactive
◦Specific failing memory DIMM identification
◦Tests video card memory
◦Launches DST Smart tests for both SATA and SAS drives
◦Many other tests and diagnostics
●Warranty Code output – A unique warranty code is generated for each failure which can be used
to validate diagnostic use for a specific system
●Easy to use - uses similar user interface as previous field diagnostics, HP Insight Diagnostics
●True End2End diagnostics – same diagnostics modules used in factory
●Easy to obtain
◦Download from Web
◦USB key bootable or CD bootable
◦Included with restore media
It is expected that these Vision diagnostics will be run on supported products when attempting to
troubleshoot system issues.
Overview
The HP Vision Field Diagnostics utility allows you to view information about the hardware configuration
of the workstation and perform hardware diagnostic tests on the subsystems of the workstation. The
utility simplifies the process of effectively identifying, diagnosing, and isolating hardware issues.
ENWW Self-troubleshooting with HP Vision Field Diagnostics 183 
						

							The Survey tab is displayed when you invoke HP Vision Field Diagnostics. This tab shows the current
configuration of the workstation. From the Survey tab, there is access to several categories of
information about the workstation. Other tabs provide additional information, including diagnostic test
options and test results. The information in each screen of the utility can be saved as an html file and
stored on a diskette or USB flash drive.
Use HP Vision Field Diagnostics to determine if all the devices installed on the workstation are
recognized by the system and functioning properly. Running tests is optional but recommended after
installing or connecting a new device.
You should run tests, save the test results, and print them so that you have printed reports available
before placing a call to the Customer Support Center.
NOTE:Third-party devices may not be detected by HP Vision Field Diagnostics.

							User interface
The HP Vision Field Diagnostics application provides six major functions, accessible through Tabs.
These functions are:
●Survey — Your current system hardware information.
●Test — List all diagnostics available for your system. Tests are started there.
●Status — This screen shows progress and status of currently running diagnostics.
●History — All past diagnostics runs and status are listed there.
●Errors — All past diagnostics failures are listed there.

diagnostics without the need to restart your entire system.
●Save button — If available, save your system survey, test history or error data as an HTML file to
a floppy disk or a USB key drive.
Survey tab
The Survey tab shows your system hardware information, organized into eleven Categories (for example
Processors) and device instances (for example Processor 1).
The amount of information displayed can be controlled by selecting a combination of View Level and
Category.
The View Levels include:
●Overview — shows high level summary of the system hardware. This is the default view level.
●Summary — gives limited configuration data for each specific Category.
●Advanced — offers more technical and low-level data for the computer-savvy user.
The Categories Levels include:
●All — Shows all Categories.
●Architecture — Shows system architecture information such as high level PCI devices, low level
SMBIOS, CMOS and PCI configuration space data.
●Audio — Shows all embedded and add-on audio devices.
●Asset Control — Shows asset control related information such as product name, serial number,
asset tag, and universal unique ID information.
●Communication — Shows communication devices such as serial, parallel, USB, network,
Firewire, modem, and Bluetooth ports and devices.
●Graphics — Shows all embedded and add-on video cards.
●Input Devices — Shows user input devices such as all connected mice and keyboards.

							Test tab
The Test tab lists all available diagnostics. The lists have been tailored according to your system
configuration. Individual test may be selected or unselected. The following Test Modes exist:
●Quick — This test selection was picked to perform quickly while covering your entire hardware.
Test parameters cannot be modified.
●Complete — This test selection offers all available tests and may take a long time to complete.
Test parameters cannot be modified.
●Custom — Like Complete this test selection offers all available tests. The test parameters may be
modified to fit specific needs. For advanced users only!
By default, the three test modes do not display prompts and require no interaction. If errors are found,
they are displayed when testing is complete.
However, for each test type, you may also optionally add interactive tests by clicking the Include
interactive tests box under Test mode. Selecting interactive tests provides the maximum control over
the testing process. The diagnostic software will prompt you for input during tests.
NOTE:Memory can not be tested from within the HP Vision Field Diagnostics application. To test the
memory in your workstation, exit HP Vision Field Diagnostic, boot to either the CD or USB flash drive
and select HP Memory Test from the boot menu.
The Duration of Test options control the duration of the test sequence. The following options are
available:
●Number of loops — A test selection will run once by default. Enter a positive number to make a
test selection run many times.
●Total test time (hours:minutes) — Alternatively, the test selection can be set to run for a specified
amount of time. This does not guarantee that all tests will run if the entered time is less than the
necessary time to run all the tests
●Stop at first error— Check this option to stop test execution as soon as one error is encountered.
The following Test Controls exist:
●Select All, Unselect All button — This button toggles to select or unselect all the tests from the
test selection tree.
●Expand, Collapse button — This button toggles to expand or collapse the test selection tree.
●Start Test button — Click this button to start executing all selected tests. HP Vision Field
Diagnostics will automatically switch to the Status tab in order to keep track of the test execution
and status.
WARNING!Once started, do not reboot or power off your computer until all the tests have been
completed.
To begin testing:
1.Select the Test tab.
2.Select the type of tests you want to run: Quick, Complete, or Custom.
3.Include optional interactive tests by selecting Include interactive tests.
4.Choose how you want the test to be executed, either Number of Loops or Total Test Time. When
choosing to run the test over a specified number of loops, enter the number of loops to perform. If
you want the diagnostic test for a specified time period, enter the amount of time in minutes.
