Having the same issue with an NM-D472, led blinks for 12 times and occasionally when it stops blinking and pressing the power button 3v_alw becomes .8v while the enable pin for pu5601 is pulled low, pu5601 also gets hot because something is drawing too much current from 3VLP, so far I have replaced super io/ec and lv5116a and it has made no difference, I'm starting to think its a dead CPU/PCH but it seems to properly load the new ec firmware onto a blank ec, disconnecting 3v pch with a blank chip it doesn't program a blank ec

3vlp is 130k ohm
3v_alw is 9.2k ohm
