As for the keyboard backlight, it's not available because the driver only supports and older version of the keyboard backlight control interface which does not seem to be available. As for "LUK2019" and "IDEA2004", those devices don't seem to be that interesting (I might be wrong though) at first glance since they seem to contain more or less nothing as far as I can see: Device (HKDV) { Name (_HID, "LHK2019") // _HID: Hardware ID Name (_UID, Zero) // _UID: Unique ID Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0F) } } ... Scope (^^EC0) { Device (ITSD) { Name (_HID, "IDEA2004") // _HID: Hardware ID Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x0F) } } } As for the, I assume, screen backlight and Fn keys, unfortunately I cannot help. --=20 You may reply to this email to add a comment.
