I have this Problem with Dell Inspiron 3520 40_DV15 MLK MB 11280 mother board,
I couldn't found board view for this board I have similar schematic currently board not turning on.

+RTC_VCC is ok

RTC_RST# 2.5V on q2102 drain pin, in this mosfet gate RTCRST_ON_ showing 0V also kbc RTCRST_ON is 0V

SRTC_RST# also 2.5V

3D3V_AUX_S5 is precent
S5_ENABLE is ok
5V_S5 is ok
3D3V_S5 is ok
Ac in# is 0V
+5VA_PCH_VCC5REFSUS i don't know where to check

PM_RSMRST# No voltage

Re: Dell Inspiron 3520 rsmrst missing Help

The diagram you're referring to is for 10316-1 with HM65 chipset whereas your mb is 11280-1 with HM76 chipset. A more appropriate diagram in this case is DELL INSPIRON 3420-11282-1. Its available in the forum.

The assumption was made based on the schematic I have in my hand. According to this schematic, the source is connected to GND. The schematic you uploaded illegible...

Re: Dell Inspiron 3520 rsmrst missing Help



PU4002 is a P-channel Mosfet. The internal diode will conduct at +19V to switch on the +3/5V LDO, but this doesn't necessarily mean full switching
The BQ24707ARGRR internal logic includes a delay. I suggest you test the PU4002 and the Gate line. There should be 2 resistors. If the PU4002 is not in use, trace it back...

Re: Dell Inspiron 3520 rsmrst missing Help

when I grounded PR4019 pin 2 manually PU4002 Gate 1.4V valtage rise up to 9V, but in both cases 19V pass to the other side,

in the other hand RTCRST_ON not generating by kbc 120 pin, now I have no idea how to fix this one

Re: Dell Inspiron 3520 rsmrst missing Help



PU4002 Gate valtage is - 1.4V
I chaneged PR4019 from same donor board
I also changed PQ4006
I reprograme bios again
also I changed q2703 and q2701 but the problem is same
also I grounded PR4019 pin 2 manually but nothing changed,
I don't think PQ4006 open drain MOSFET because I injected gate pin 3V then source pin become 0V but the problem still same,

I feel like probelm with q2102 as I mentioned before in this mosfet drain pin RTC_RST# is 2.5 V mosfet gate RTCRST_ON_...
