HP Insight Diagnostics 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. 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. You can find Insight Diagnostics on the Documentation and Diagnostics CD that shipped with the computer. You can also download the tool from the HP Web site as follows: 1. Go to www.hp.com 2. Click the Software & Download driver link. 3. Enter the product number (for example, dx2400) in the text box and press the Enter key. 4. Select the specific product. 5. Select the OS. 6.
