Re: MacBook Pro A1990 doest turn on
The mosfet readings look ok.
Try to dial up a higher voltage of 0v9 and check for a heated capacitor. Review the CPU Vcore input tantalum (polarized black) caps which create the 3 phase switching regulator circuit - collectively to support 128A of switching current.
