ok so I have this Lenovo y50-70 touch that has a no charge problem, maybe someone can point me in the right Direction since I cannot find a schematic for Borderview
what are you guys opinion on where to start to check why its not charging?
Back story:
I bought this with a bad charging port, previous owner stated it charge fine but his kid kicked the cord and rip the plug and port out.
so I ordered a new one, but when I was replacing the plug the open wire touch and made a spark because I completely forgot to unplug the battery.
so I went a head changed out the plug and put it back together and it doesn't charge, no light or nothing i know that laptop works had a full charge before the battery drained.
thing I done so far:
replaced the port.
replaced one of the mosfets because I had an extra one laying around, but no luck
I tested the volt on the plug side of the board it gets 19V
I measured the first mosfet PQ301 the drain and gate both sides measure 19v
mosfet PQ302 gate measure 19v in and drain out 5v both the old mosfet and new one measure the same
