Asl50 Lac921p Rev 10 Schematic Exclusive __link__ Here

The schematic shows a pi-filter (C1, L1, C2) with a surge-rated varistor (MOV1). Rev 10 adds a 10Ω NTC thermistor (TH1) in series with the live line—previously omitted. This suggests the Rev 10 design addresses inrush current issues from capacitive loads.

The entry point of the 19V rail uses dual N-channel MOSFETs (typically AO4407A or similar) to isolate the DC-in jack from the main system rail ( B+ ).

If a control signal is missing, locate the pull-up and pull-down resistors on the schematic. A shifted value in a mega-ohm resistor can stall the entire sequence. Conclusion
