Hi
i have an 820-3208 in an S0 state. but no fan spin.
The missing S0 rails are
PP0V75_S0_DDRVTT
PPVCCSA_S0_CPU
PPVCORE_S0_CPU
PPVCORE_S0_AXG
incidentally PP1V5_S3_CPU_VCCD is at 1.35v and not 1.5v
all_sys_pwrgd is not present (50mv)
I have changed Q7950 twice just in case
inputs on Q7950 are
VMON_Q2_BASE 1.06v
VMON_Q3_BASE 1.3v
VMON_Q4_BASE 0.7v
S0PGD 0.65v
the voltages coming in to each of the resistors (and dividers) feeding Q7950 are fine. the resistors themselves are fine. and the all_sys_pwrgd resistors also seem fine
any thoughts on where to go next with this board?
thanks
justin
