13 HP PC Hardware Diagnostics (UEFI)

HP PC Hardware Diagnostics is a Unied 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.

NOTE: To start BIOS on a convertible computer, your computer must be in notebook mode and you must use

the keyboard attached to your tablet. The on-screen keyboard, which displays in tablet mode, cannot access

BIOS.
