DDR_VREF_S3(0.75V) Present??

Sorry for delay update ,its showing (0.678 v)

Re: Dell 15-3000 Janus _intel-mb 13302-1 Schematic

0.678v is corrrect. You need to check U3601. You have 3v3_S0- right?? Both 3v & 5V S0 are enabled by PM_SLP_S3#-so it cant be missing. The only thing i can conclude is you have some sort of shorted component on 5V_S0. What is the resistance on pin13-14 of U3601?? Have you checked u3502/3503/3504 for shorting??

Now, i'm confused. You mean you dont have PM_SLP_S3# ???? I've read your post about pu4503 heating and kbc replacement. Please clarify. Btw, what is your Dc consumption -offline and online??

Yes Don't have PM_SLP_S3#, no activity at all
DC consumption both on & off 0.01
checked u3503,3504,3505,
a doubt pc4523 is missing or it ok,

Re: Dell 15-3000 Janus _intel-mb 13302-1 Schematic

PM_SLP_S3# is missing so you need to get backwards. Check the following:
01.RTCRST#
02.VCCDSW
03.DPWROK
04.BATLOW#
05.SLP_SUS#
06.VCCSUS#
07.RSMRST#
08.SUSWARN#
09.SUSCLK
10.ACPREsent
11.SUS_ACK#
