If the voltage reads 0V, the internal BMS may have tripped. It will not accept a charge from the standard charger. gs44b gs54b nm-c561 schematic

1. Open the GS44B boardview (or GS54B depending on your physical board).
2. In the search bar, type 3V3_AUX or +3VALW.
3. The software will highlight all pads with that net name.
4. Double-click the specific pin of the power IC (e.g., Pin 14 of PU401).
5. Look at the resistance (ohms) to ground. The schematic (PDF) will tell you the expected value (usually >100 Ohms). If it is 2 Ohms, you have a shorted capacitor.

Repair and Maintenance: Technicians often require schematics to diagnose and fix issues within complex electronic circuits. The diagram provides a visual representation of the components, their connections, and the flow of signals or power. GS44B/GS54B NM-C561 schematic refers to the core technical
