11 Using 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 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 code is generated. This ID code 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, and quickly press esc.
2. Press f2.
The BIOS searches three places for the diagnostic tools, in the following order:
a. Connected USB drive

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.
