820-3437 no power

[Gmorb]

I get pp3v3_s4 but 3v3_s3 is low .400v now i assumed it was smc so i switched it out issue persist odd thing is i did get it to power on once by using power on pads. I have had no luck doing so again. Smc_on_off_L stays at a constant 3.4v after using power on pads not sure if thats the issue? Plz help.

History? It should of course just auto power on. PPBUS, 3v3_S5 etc?
