Hi Kobeto,

Yes you are right, this is likely because your board isn't listed in
the hp_wmi_feature_boards[] array. Can you share the output of:

Embedded Controller:
# modprobe ec_sys
# xxd /sys/kernel/debug/ec/ec0/io

DMI information:
# dmidecode

ACPI tables:
# acpidump

I think these should be sufficient to build a patch for you to test.
