6. HP Hardware Diagnostics and Tools
HP oers 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 (UEFI)
HP PC Hardware Diagnostics is a Unied 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 HP PC Hardware Diagnostics Tool (http://www8.hp.com/us/en/campaigns/
hpsupportassistant/pc-diags.html?jumpid=va_r602_us/en/any/pps/pl_ot_ob_ds_pd/
HP_PC_Hardware_Diagnostics_cc/dt) supports a wide range of HP computers.
The tool runs outside the operating system so that it can isolate hardware failures from software issues,
whether caused by the operating system or applications. In reality, you can determine many problems using this
tool if the issue is a defective part or a loose connection (for example, reseating the keyboard cable after the tool
reports a keyboard error).
The tool has three major functions:
● System Tests check the computer’s hardware to verify that 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 rolls
back to a previous version.
1. Turn on or restart the computer, quickly press the esc key on the computer, and then press f2. The BIOS
searches three places for the diagnostic tools, in the following order:
●
1. Connected USB drive
2. Hard drive
3. BIOS
