13269-1 Fx3mc rev:A00 not getting On

[pratyush]

not getting Rsm_rst#_KBC (pin no.15 KBC24)
nd SUSCLK_KBC(pin no.77 KBC24)
followed schematic all other pre required signals are present
And I got a paid video on youtube where he challenged that in This case no prob. of CPU or KBC24 io..
Plz help..

Can you suggest necessary signals to check in RTC section...I tried to find some faults but unable to get it...

I was not able to solve this problem on this very model with the exact same problem RSMRST# missing. As far as i know, Without RSMRST# signal pc will not power on as SUS signals will not be generated by inbuilt cpu+pch . I too tried digging very hard but unfortunately gave up.

Btw, I tried putting 3.3V on RSMRST# pin15 of KBC NPCE285 and the mb switched on with all voltage on all coils but still no display. On further digging i found that DRAMRST signal was missing on PIN30 Of ram slot. I tried to jumper that too with 1.35V but it didnt worked. I still suspect it's some sort of malfunction in inbuilt CPU+PCH die.

RSMRST# is sent out by EC. SLP_S4# will come after RSMRST#.
Follow steps -7, -6, -5, -4, -3, -2.
RSMRST# is step -1, the one you're missing.

Check if you have SLP_SUS#.

Also schematics is a bit confusing and it seems like there are different variants. Look at Q1701 circuit and try to find the parts that are present or not present on the board.
