La-e791p Rev 2.0 Schematic Diagram ((link)) Site

If your lab power supply shows a "short to ground," the schematic helps you isolate the rail. By identifying which capacitors and MOSFETs are linked to a specific voltage line, you can use a multimeter (or thermal camera) to find the exact component causing the failure. Summary for Technicians

The EC handles power sequencing. In the schematic, you will see the "Power Button" matrix. La-e791p Rev 2.0 Schematic Diagram
