Im working on this board day11amb6e0. On the KBC Im gettting
RSMRST# 3.3v then to 0v immediately
S5_ON 3.3v then 0v immediately.
No +3v to KBC
Mainon stays at 0v

Also theres no +5vs5 or +3vs5

PU11
vin is ok
+3vpcu is ok +3v
S5_on 3.3v then 0v immediately
Pgood 0v
En2 4.5v


PU12
S5_on 3.3v then 0v immediately
+5VPCU ok 5v
pgood 0v.

What would cause the S5_on to drop to 0v ?
When S5_on is 3.3v then I get +5VS5 and +3VS5 for a couple of seconds then both drop to 0v because s5_on goes low.

Any ideas?

Still struggling with this, any input appreciated.

ec_wrst#, acin, lid_ec#, ad_id, ad_type, 3v_rtc, rtc_clock_32768 ?

ec_wrst =3.3v
Acin = 3v
Lid_ec# = 3.3v
ad_id = .6v
ad_type = .6v
3v_rtc = 2.7v
rtc_clock_32768 not on this board

A block diagram or signal order of Haswell chip would be helpful. Im getting S5_on which is generating +3vs5 and +5vs5 for a second or so when the power button is pressed then s5_on drops to 0v
