Using HP PC Hardware Diagnostics (UEFI)
HP PC Hardware Diagnostics is a
8QLƬHG
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.
