Hello have this Lenovo E480 that after storm wont work
NM-B421
two chargers USB-C dont give me voltage. so i cut one and with cable connect my source and see 2.7W steady. Found hot area near power connector with burning resistor. it is so tiny that i cannot see its value
when connect charger on one side of this resistor is 20V on other side is pulling down to ground by Q4202
If anybody have schematic, share on schematics page
