When I choose the shutdown option, my Acer H340 closes and after 2-4 seconds it turns on again (I have two of these h340 and both behave the same way), WOL I have turned off in options, I do not have anything in USB ports (even during shutdown I do not have plugged cable in RJ45), On windows (7, 8, 2003, 2011) I do not have such problems Has anyone met with this or an idea how to solve it?
