Diagnostics for Windows

The Diagnostics for Windows (DFW) utility allows you to view

information about the hardware and software configuration of the

computer while running Microsoft Windows XP. It also allows you to

perform hardware and software tests on the subsystems of the

computer.

When you invoke Diagnostics for Windows, the Overview screen is

displayed, which shows the current configuration of the computer.

From the Overview screen, there is access to several categories of

information about the computer and the Test tab. The information in

every screen of the utility can be saved to a file or printed.

✎To test all subsystems, you must log in as the administrator. If you do

not log in as the administrator, you will be unable to test some

subsystems. The inability to test a subsystem will be indicated by an

error message under the subsystem name in the Test window or by

shaded check boxes that cannot be selected.

Use Diagnostics for Windows to determine if all the devices installed

on the computer are recognized by the system and functioning

properly. Running tests is optional but recommended after installing

or connecting a new device.

Third-party devices not supported by HP may not be detected by

Diagnostics for Windows. Save, print, or display the information

generated by the utility. You should run tests and have the printed

report available before placing a call to the Customer Support Center.
