Please reply with new thread, insted of a comment.
Is more easy to follow the thread.

Check if PM_PWRBTN_L reacts (drop pulse) when trigger SMC_ONOFF_L signal; use R5015/16 pads, instead of power button.
To test on battery only (no charger), of course.

battery only test result, using R5015/16 pad does NOT work , also PM_PWRBTN_L goes down when triggered
SMC_ONOFF_L signal

also i notice if i turn on mac then disconnect power and run with batter ,,, then i press power button for .001 sec it shuts off , when it run battery it shuts off right way as soon as i press power button

If PM_PWRBTN_L reacts, then (ALL) PM_SLP_Sx_L signals should pulse, at least; check that.
