HP e-DiagTools Hardware Diagnostics
The first step in solving a problem with a workstation is diagnosis.
HP’s e-DiagTools helps you diagnose hardware-related problems on a HP computer. It is
a series of tools designed to help you to:
• Distinguish between software and hardware problems
• Verify the correct functioning of a HP computer
• Diagnose hardware-related problems
• Provide precise information to support providers so that they can solve any problem
quickly and effectively.
e-DiagTools is not a repair tool.
Overview Of e-DiagTools
e-DiagTools has three main components:
• The Pre-Boot Diagnostics, which emit a buzzing sound followed by an audible set of
beeps that helps diagnose a problem when the computer cannot boot. Refer to
“Pre-boot Diagnostics” on page 160.
• The e-DiagTools core tests, which provide hardware detection, basic and advanced
system tests, and the possibility to generate a Support Ticket with a complete record
of the test results and the PC’s configuration.
• A set of functions to forward the Support Ticket to your authorized support provider
via e-mail, and to retrieve and flash the latest BIOS version for your computer.
HP e-DiagTools is supplied on the following media:
• The Utility Partition pre-installed on your hard disk (recommended). This does not
apply to FastRaid models.
• The HP Recovery CD-ROM that was supplied with your workstation.
• The HP DiagTools CD-ROM.
NOTE Only the Utility Partition version of e-DiagTools supports the full range of e-features.
When you run e-DiagTools from a CD-ROM you will not be able to send the Support
Ticket via e-mail or to update the BIOS.
If you are running e-DiagTools from a CD-ROM, the option to start from the CD-ROM is
enabled and the CD-ROM is configured to be the first device to boot from. After running
e-DiagTools, restore the original Setup values.
Alternatively, you can set the boot device priority by pressing the F8 key when the logo
screen is displayed after restarting your computer.
