I was wondering if it's possible to have Panther (Asus
ChromeBox - Haswell/Lynxpoint) power on when AC power
connected regardless of the previous power state.
Currently, the box will power on if AC power is lost and
the device was powered on, but not if powered off. I have
a use case where it would be convenient to be able to
power on the boxes by toggling AC power (eg, the boxes are
not within physical reach). I modified the CMOS default
setting for 'power_on_after_fail' to be enabled and
verified its status with nvramtool. I also tried
modifying lpc.c/smihandler.c in the southbridge code to
force MAINBOARD_POWER_ON (rather than
MAINBOARD_POWER_KEEP) in all cases, to no avail.<br>
<br>
Am I approaching this from the wrong angle, or is it
perhaps not possible with these boxes?<br>

<div>This might be due to the SuperIO instead of the
Southbridge. Panther does call
it8772f_ac_resume_southbridge() which *should* be making
the southbridge the one responsible for the power behavior
when AC is applied, but as a first test you could try
removing that call to see if the default SuperIO behavior
is closer to what you want.</div>

Hi Duncan, I tried removing the call as suggested, but it didn't
change the behavior at all. Any thoughts as to where to look next?<br>
<br>
thanks!<br>
