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.

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