looking help on lenovo y50-70 mboard: la-b111p zivy2
laptop had shorted capacitor on B+ battery rail and was dead, CHG_B+ PC305
i replaced cap with same healthy cap and laptop started working, i noticed
input mosfest got hot when i start laptop, but when battery is connected vin mosfets get insanely hot but laptop charges and works with battery
-i can hear small spark sound when charger is connected
something draws lots of current but i cant figure out what component it is
-BATT+ mosfet PQ303 gets also pretty hot but when i charge battery it gets insanely hot and it is next to cap i changed
-PU301 battery charge ic is not getting hot
-also pch gets warm / sometimes hot
