Using 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 tablet hardware is functioning properly. The tool runs

the operating system or other software components.
To start HP PC Hardware Diagnostics UEFI:
1.
Turn on or restart the tablet, quickly press the Windows button on the tablet, and then press
+f2.
The BIOS searches three places for the diagnostic tools, in the following order:
