Hey Guys,
I'm facing a very mysterious Problem, I've got a Motherboard Quanta G34A Which cannot be turned on with charger but it can be turned on with battery. when i connect a faulty but Original battery Laptop Turned on with charger. I've checked all Charging IC PU1 (ISL88750) Voltages, Everything is perfect but when i checked 3/5V Coils there is no voltages. I've checked VIN voltages on PU2 (SY8208B) for 3V IC that is only 8,7 VOlts. So i think VIN is not generating properly. I think VIN should be 19V. Anybody can give me any idea what should i do? I'm uploading Schematic Diagram n BoardView....
