[Bug Report]: Power button suppression when fingerprint scanner is polling does not function on Framework 13 AMD

[TheBlueKingLP]

The Problem

I sometimes presses the power button accidentally(putting a bit too much pressure on it and triggered the button under the sensor) when my intention was to use the fingerprint reader.

Proposed solution

An option for enabling a delay that requires the user to hold the power button for maybe 0.5 second to 1 second, would be appreciated. This is the behavior on some of my other laptops that has the fingerprint sensor on the power button.

When the fingerprint reader is in use, i.e. when OS requests authentication, the power button functionality is already disabled.
There is no need for the workaround you describe.

Could you describe the exact situation that you are having issues with?

[JohnAZoidberg]

Which device are you using? Maybe there's a bug on the particular system that you are using?
Here you can see the code that is responsible for this on the Intel Core Ultra Series 1 system:

EmbeddedController/zephyr/program/framework/src/board_function.c

Lines 116 to 132 in 74a8e9a

	/**
	* Ignore the power button signal when fp control enable
	*
	* If user removes the fingerprint module, the fp control signal is always high.
	* Only enable this feature when the system does not enable the standalone mode,
	* and system state in S0.
	*/
	if (gpio_pin_get_dt(GPIO_DT_FROM_ALIAS(gpio_check_fp_control)) &&
	chipset_in_state(CHIPSET_STATE_ON) && !get_standalone_mode()) {
	if ((get_time().val < stime.val + 4 * SECOND) && !power_button_state) {
	hook_call_deferred(&power_button_signal_deferred_data, 100 * MSEC);
	return;
	} else if ((get_time().val > stime.val + 4 * SECOND) && !power_button_state)
	chipset_force_shutdown(CHIPSET_SHUTDOWN_BOARD_CUSTOM);
	else
	stime.val = 0;
	}

Here you can see me trying it on the new AMD Ryzen AI 300 system. The power button does not react, while the system is requesting fingerprint authentication.

Interesting, that is not the case for me. I just tried the fprintd-verify command as well, however unlike in your case, my Framework laptop went into sleep mode.
My unit is a Framework 13 AMD.

In this case, I assume this would be a bug instead of a feature request then?

That's right, will try to reproduce on AMD Ryzen 7040.
