I have 2 boards with same issue 820-00165-a and 820-3437-b.
They both are drawing 150ma from power supply.
I checked q8150 - only voltage that is present there is S0PGD_C and it is 3.285v
I replaced Q8159,R8153,R8156,R8154.
Measured all rest near by resistors for their values against schematic.
Replaced U1950 just in case.
Single voltage that is present on U1950 is Pin8 and it is 3.4v
i guess i am not in S0 state as i am missing 5v on J6000
PPBUS is 8.58v
Any ideas?
