HP Insight Diagnostics

The HP Insight Diagnostics utility allows you to view information about the hardware configu-
ration of the computer and perform hardware diagnostic tests on the subsystems of the com-
puter. 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 cur-
rent 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 recog-
nized 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 avail-
able before placing a call to the Customer Support Center.
Insight Diagnostics may be found on the Documentation and Diagnostics CD that shipped with
the computer. The tool may also be downloaded from the HP Web site using the following pro-
cedure:
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. Click the Diagnostics link.
7. Select HP Insight Diagnostics Offline Edition.
8. Select the proper language and click Download.
NOTE: The download includes instructions on how to create a bootable CD.

Clearing CMOS

1. Turn off the computer and any external devices, and disconnect the power cord from the
power outlet.
2. Remove the access panel.
3. Remove the RTC battery.
4. On the system board, move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear
CMOS). Keep the cap on pins 1-2 for about 5~10 seconds, and then move the cap back to
pins 2-3.
5. Replace the access panel, external devices, reconnect the power cord, and then turn on the
computer.
6. Hold down F1 during the boot process to enter BIOS setup and re-enter data.
CAUTION: Other than when clearing CMOS, never remove the cap from the default position.
Removing the cap will cause system boot failure.
Recommended Action
Upgrade the BIOS to proper version.
1. Verify the correct ROM.
2. Flash the ROM if needed.
3. If an expansion board was recently
added, remove it to see if the problem
remains.
4. Clear CMOS.

be a problem with the expansion card.
6. Replace the system board.
No action required.
