2 is not equal 4!
Even if you ad RTC clock, which is not I asked for.
What about PCH_INTRUDER_L and PCH_INTVRMEN?
Are not both in the same RTC block of PCH???
Check if any PM_SLP_Sx_L signal pulses at same time with PM_PWRBTN_L, when trigger SMC_ONOFF_L.
In this case, your problem is PCH (CPU) related.
It gets the signal from SMC, but doesn't reply.
PCH_DSWVRMEN, PM_BATLOW_L are present?
Be sure to use original 60/85W Magsafe 2 charger.
Some people complain this board didn't start without both charger and battery connected.
