hi guys
i have two motherboard with same problem
without ram use abour 0.25A
with ram use 0.4A
no display on eDP or crt
screen turnes on but just black
i flash bios but no change
3.3V,5V,1.35V, 1.05V,1.7V is good
what signal or voltage should i check?
how can i find cpu is dead or no?
thanks all

You flashed KB9012/9022 multicontroller? Main bios had clear ME region? How about POST codes on LPC bus?
