Hi, I have this board which I have been checking, have all the rails to S0 state, but don´t have PPVCORE_S0_CPU and it is supposed to be created by U7400 but don´t know which rails I need to make sure U7400 is working OK. I replaced U7400 and no change... What else should I check?
The resistance on that line to ground is 2 ohms which on a working board is the same, so I don´t know where else to look.

Thanks!
