HP PC Hardware Diagnostics (UEFI)

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 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.
When HP PC Hardware Diagnostics (UEFI) detects a failure that requires hardware replacement, a 24-digit
Failure ID is generated. This ID can then be provided to support to help determine how to correct the problem.
NOTE: To start diagnostics on a convertible computer, your computer must be in notebook mode and you
must use the keyboard attached.
To start HP PC Hardware Diagnostics (UEFI), follow these steps:
1. Turn on or restart the computer, quickly press esc.
NOTE:
you must use a Windows computer to download and create the HP UEFI support environment because
only .exe files are offered.
2. Press or tap f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive
NOTE:
HP PC Hardware Diagnostics (UEFI) to a USB device on page

3. When the diagnostic tool opens, select the type of diagnostic test you want to run, and then follow
the on-screen instructions.
NOTE: If you need to stop a diagnostic test, press esc.
