HP Z8 G4 Maintenance And Service Guide

Using HP PC Hardware Diagnostics UEFI
HP PC Hardware Diagnostics UEFI (Unied Extensible Firmware Interface) allows you to run diagnostic tests to
determine whether the computer hardware is functioning properly. 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.
If your PC will not boot into Windows, you can use HP PC Hardware Diagnostics UEFI to diagnose
hardware issues.
When HP PC Hardware Diagnostics UEFI detects a failure that requires hardware replacement, a 24-digit Failure
ID code is generated. For assistance in correcting the problem, contact support, and provide the Failure ID code.
NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode, and you
must use the attached keyboard.
NOTE: If you need to stop a diagnostic test, press esc.
Starting HP PC Hardware Diagnostics UEFI
To start HP PC Hardware Diagnostics UEFI, follow these steps:
1. Turn on or restart the computer, and quickly press esc.
2. Press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive
NOTE: To download the HP PC Hardware Diagnostics UEFI tool to a USB drive, see Downloading HP
PC Hardware Diagnostics UEFI to a USB device on page 86.
b. Hard drive
c. BIOS
3. When the diagnostic tool opens, select the type of diagnostic test you want to run, and then follow the on-
screen instructions.
Downloading HP PC Hardware Diagnostics UEFI to a USB device
Downloading HP PC Hardware Diagnostics UEFI to a USB device (ash drive) can be useful in the
following situations:
●
HP PC Hardware Diagnostics UEFI is not included in the preinstall image.
●
HP PC Hardware Diagnostics UEFI is not included in the HP Tool partition.
●
