The first two mosfets near the power jack often fail. If they are scorching hot to the touch, they are likely shorted. Multimeter in continuity mode.
Replace the shorted mosfet (usually a 4407A or similar). 2. Charging IC (PWM) hannstar j mv4 94v0 e89382 boardview hot
A boardview file is a digital map of the PCB. It allows you to: Follow a 19V rail to find where it breaks. The first two mosfets near the power jack often fail
Instantly find a tiny resistor or capacitor. Identify pins: See which pin on an IC leads to which pad. hannstar j mv4 94v0 e89382 boardview hot
