--- Comment #1 from Jani Nikula <jani.nikula at intel.com> ---
Do you boot in UEFI mode? If not, please switch to UEFI boot.

The VBT (which may be different for UEFI vs. legacy boot) indicates minimum
brightness of 0 which we respect. The vendor could have chosen non-zero and set
it to VBT if so desired.

The i915 kernel driver is not the place to work around hp_wmi hotkey issues.
