Cedar 13269-1 FX3MC DCBATOUT short

[ReparaPC]

I've a FXMC motherboard with a short on the DCBATOUT line.The moment the charger is plugged in to the board, it will block itself for protection. I have remove PR4402 for isolating the short, and making sure the short doesn't come from AD+_TO_SYS.

PU4502 was shorted on all of the pins. Removing it solved the short on DCBATOUT. Now, shorts on PWR_DCBATOUT_5V and PWR_DCBATOUT_3DV3 are present.

PU4502 is likely fine. Inject 1V/5A from dc supply on PR4402,pin2 to find out the shorted component. Put your meter probe on PR4402,pin2 and touch the other probe on Big coils one by one(Meter in diode mode). The coil which shows very low resistance is the shorted area. Findout the high side mosfet connected to that coil and check it. It could be a capacitor on +19V rail also.

PS: Dont apply any power to mb while PU4502 is de soldered.Else will go to trash.
