Hi,
I have that board which has the quarter fan spin. It has the normal sign of corrosion on the top edge of the board but looks quite good though.
I have measured the voltage drop to ground on the S3 and S0 rails and have found a 0.115v drop ground on PP5V_S3 compared to a 0.425v drop to ground on a known working board.
Can someone confirm this measurement?
Also, since it is not a complete short circuit, I have tried removing a few chips, like all the audio amps (U6610, U6620, U6630, U6201), some USB chips (U4800, U4600) but no cigar.
I do not believe it has to be a caps, am I right to think that?
Have anyone experienced that and could give me a hint?
