Dear comunity
I have a 820-3437 logic board that the PP5V_S4RS3 and PP3V3_S5_REG_R (U7501) sources are dropping. I have seen that the enables of these sources the same thing happens to them, dropping first P5VS4RS3_EN and then P3V3S5_EN_R. The funny thing is that this cycle of dropping and running is ALWAYS repeated 2 times until it stabilizes and is running smoothly.
Any idea why this always happens 2 times ?
