    Nope, it is "Hardware Reduced (V5) : 0". Now the FADT is also at
    https://linuxtv.org/~js/e200ha/

    I added CONFIG_INPUT_SOC_BUTTON_ARRAY=y, but no joy.
    Maybe because the _HID is INTCFD9, only _CID is PNP0C40?
    It also has a _DSM with UUID dfbcf3c5-e7a5-44e6-9c1f-29c76f6e059c.

    BTW, lsinput already lists two "Power Button" devices,
    phys : "PNP0C0C/button/input0"
    phys : "LNXPWRBN/button/input0"

    None of them generates events in input-events.


    Thanks,
    Johannes
