On the U7501 I am getting the Enable P3V3S5_EN_R of 3.3 volt but NO Enable P5VS4RS3_EN_R of 5 volts. I get 0 volts out here whereas it should be 3.4V if I am correct. P5VS4RS3_EN comes out from S4_PWR_EN & PM_SLP_S4_L ... I am missing PM_SLP_S4_L too, 0 volts out here... Where can the problem be????
