The HP Insight Diagnostics utility allows you to view information about the hardware configuration of
the computer and perform hardware diagnostic tests on the subsystems of the computer. The utility
simplifies the process of effectively identifying, diagnosing, and isolating hardware issues.
The Survey tab is displayed when you invoke HP Insight Diagnostics. This tab shows the current
configuration of the computer. From the Survey tab, there is access to several categories of information
about the computer. 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 HP Drive Key.
Use HP Insight Diagnostics 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.
