Another possibility is that you have excessively deep sleep enabled on too many devices (like if 'tlp' is installed) and some machines can't wake up from that. Make sure you don't have tlp installed and also try adding a USB mouse to wake the machine up with - you can also then see if the mouse is powered when trying to wake the system.
