ACPI + PowerButton

NTDEV
1

Hi all,

I’d like to handle the power button on atx box. I tried to do the
following:

  • write a functional driver and install it wit hwid ACPI/PNP0c0c ( and
    ACPI/FixedButton too )
  • in driver’s AddDevice function, get ACPI_INTERFACE_STANDARD table
  • call RegisterForNotification function
    Unfortunately, no notifications arrive :frowning: I tried to connect to various
    GPEs, and caught moments when USB devices was plugged in and out, but
    got no events when POWER on box was pressed ! Heeelp please :slight_smile:

What does “handle the power button” mean? You want notification when it has
been pressed? You want to supercede its behavior? You want to emulate
behavior that the underlying system doesn’t actually implement?
