6. HP Hardware Diagnostics and Tools

HP offers different diagnostics and tools to diagnose hardware failure. This section describes how to use

some of these tools. Make sure to check for the latest versions before use.

HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run diagnostic

tests to determine whether the computer hardware is functioning properly. The HP PC Hardware Diagnostics

(UEFI) tool is built within BIOS (basic memory and hard drive diagnostics only), or within new hard drives

themselves. These drives contain more advanced versions of the diagnostic tool than the BIOS-based version.

In addition, for HP authorized service partners and IT professionals who need to support a mixed environment

of older and newer HP/Compaq PCs, the

diagnostic tool that supports a wide range of HP Desktop and Notebook computers.

The tool runs outside the operating system so that it can isolate hardware failures from issues that are

caused by the operating system or other software components. In reality, many problems can be determined

using this tool if the issue is a defective part or a loose connection (i.e., reseating keyboard cable after the

tool reports a keyboard error).

The tool has three major functions:

System Tests - Check the computer's hardware to assure everything is functioning properly. If your

system won't boot into Windows, try the Quick System Test. For more comprehensive testing, use the

Extensive System Test option. If the System Test did not detect a hardware problem, continue with the

Component Tests.

●

Component Tests – Focus on selected hardware components in your computer.

●

Firmware Management – Update your computer's BIOS to the latest version (available separately) or roll

back to a previous version.

To start HP PC Hardware Diagnostics (UEFI):

Turn on or restart the computer, quickly press the
