820-00165 no green light ppbus_g3h=8.18v

[Soji]

Board is very neat ppbus_g3h=8.18v
pp5v_s5=5.1v
Pp3v3_s5= pulsing
PP5v_s4rs3=0v
All_sys_pwrgd=0v
PCH SIGNALS
PPVRTC_G3H=3.3v
PCH_INTVRMEN=3.3V
PM_BATLOW_L=0v
PM_DSW_PWRGD=0v
SMC_ADAPTER_EN=0v
PCH_DSWVRMEN=3.2v

What about SMC_RESET_L?
Did you try another LIO board?

 

[Soji]

I have try another LIO board
SMC_RESET_L=3.383

 

[2informaticos]

Check U5000 (2 OF 2) signals and voltages, page 37.

 

[Soji]

SMC_RESET_L=3.3v
PP3V3_S5_SMC_VDDA=3.4v
PP1V2_S5_SMC_VDDC=1.2v
PP3V3_S5_AVREF_SMC=3.3v
SMC_EXTAL=0v
SMC_XTAL=0v
SMC_CLK32K=0v
SMC_WAKE_L=0V
SMC_TDO=3.412V
SMC_TDI=3.413V
SMC_TMS=3.412V
SMC_TCK=3.412V

"SMC_WAKE_L=0V"
Check R5002; force it with 100K instead of 1M, if needed.

 

[Soji]

What do you mean by force with 100k

 

[2informaticos]

In case it has correct 1M, like in schematic.
But still 0V on that signal...

 

[Soji]

I have replaced R5002 is a 100k resistor...no changes

 

[2informaticos]

Try another SMC (known good).
