820-3437 the PP3V3_S4SW_SNS is missing

yes sir these voltages are present.
Could you please explain a little more about the involved voltages in ALL_SYS_PWRGD geberation+

Look at page 59 of schematic.
There appear all the VMON and PGOOD signals which finally generate ALL_SYS_PWRGD.
If one of these signals misses, check the corresponding power supply...

S5_PWRGD is present
Q8150
pin1 VMON_Q1_BASE0,78v
pin3 0.11v
pin4 0,11v
pin5 VMON_Q2_BASE 0.00
pin6 S0_PGD_C 3,27v
pin7 VMON_Q3_BASE 0,70
pin 2 and 8 are unconnected according to the schematic but I measure 0.12v on them
