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. >Please CC me on any patches.
