SMC bypass - no response
All voltages steady
PPBUS_G3H - 13V
PP5V_S5 - 0V
PP3V3_S5 - 0V
PP3V3_G3H - 3.41V
PM_BATLOW_L - 0V
Slight corrosion around:
U7210/20, R3702, C3700
Quite a corrosion between U2890 and U3770, also U8440
All coils diode modes seem ok, comparing to a working board. Apart than:
Faulty Board | Working Board
CPUVR_SW1 - 0.0083 | 0.0122
CPUVR_SW2 - 0.0083 | 0.0122
SAVR_SW - 0.0146 | 0.0266
PP1V_S5G_REG - 0.0712 | 0.245
PPVCCPCH_S5G 0.0725 | 0.267
Thanks
