hi, this came in with ppbus 8.2v
i changed smc straight away, ppbus go 8.6v, machine turn on.
a few days later,customer came, the machine is dead again.
I see ppbus_g3h is 4v,sometimes 0.5v.
I remove fuse, and I have 8.6v at pin 1. so it must be system side ? do i check for short one by one?
I have seek thermal cam, but nothing shows heat.
