This is output of 'sysctl hw.acpi' (minus battery, acline and thermal
objects, not relevant here):

hw.acpi.cpu.cx_lowest: C1
hw.acpi.reset_video: 0
hw.acpi.handle_reboot: 1
hw.acpi.disable_on_reboot: 0
hw.acpi.verbose: 1
hw.acpi.s4bios: 0
hw.acpi.sleep_delay: 1
hw.acpi.suspend_state: S3
hw.acpi.standby_state: NONE
hw.acpi.lid_switch_state: NONE
hw.acpi.sleep_button_state: S3
hw.acpi.power_button_state: S5
hw.acpi.supported_sleep_state: S3 S4 S5

Setting hw.acpi.verbose to 1 did not achieve anything in console log,
i.e. pressing power button does not geenrate any event logged there.
