La-h103p | Schematic Fixed

Before applying power to a dead board, measure the resistance of the main coils (PL) to ground. A low resistance (0-2 ohms) on a 3V or 5V rail usually indicates a dead PCH or a shorted decoupling capacitor. Conclusion

The schematic helps trace the 19V (B+) rail from the power jack through protection diodes and MOSFET switches to the current sense resistor. la-h103p schematic
