Computer Diagnostic Features

HP Insight Diagnostics

✎HP Insight Diagnostics is included on CD with some computer

models only.

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.

✎Third party devices may not be detected by HP Insight Diagnostics.

Test Tab

The Test tab allows you to choose various parts of the system to test.

You can also choose the type of test and testing mode.

There are two test modes to choose from:

■Interactive Mode—Provides maximum control over the testing

process. The diagnostic software will prompt you for input during

tests that require your interaction.You may also determine

whether the test passed or failed.

■Unattended Mode—Does not display prompts and requires no

interaction. If errors are found, they are displayed when testing is

complete.

There are three types of tests to choose from:

■Quick Test—Provides a predetermined script where a sample of

each hardware component is exercised and requires no user

intervention in either Unattended or Interactive mode.

■Complete Test—Provides a predetermined script where each

hardware component is fully tested. There are more tests

available in the Interactive mode, but these require user

intervention.

■Custom Test—Provides the most flexibility in controlling the

testing of a system. The Custom Test mode allows you to

specifically select which devices, tests, and test parameters are

run.

To begin testing:

1. Select the Test tab.

2. On the left side of the tab, select the Type of Test to perform

(Quick, Complete, or Custom).

3. On the left side of the tab, select the Test Mode (Interactive or

Unattended).

While testing is in progress, a Cancel Testing button is displayed for

use if you want to cancel the test.

After testing has completed, the Cancel Testing button is replaced

with a Retest button. The Retest button will retest the last set of tests

executed. This enables you to re-run the set of tests without having to

re-enter the data in the Test tab.

The Status tab also shows:

■The devices being tested

■The tests that are running

■The overall elapsed time

■The individual elapsed test times

■The condition status of each test
