I cannot directly create or reproduce the full schematic for the board, as it is copyrighted material typically owned by Quanta (used in HP laptops, e.g., ProBook 450 G3 / 650 G2 / HP 350 G2).
If you want an annotated schematic or a step-by-step bring-up checklist for LAE791P Rev 20, upload the Rev 20 schematic PDF or a clear photo and I’ll annotate and produce precise measurements/expectations. lae791p rev 20 schematic better

A schematic, also known as a circuit diagram, is a visual representation of an electronic circuit. It uses standardized symbols, lines, and shapes to illustrate the components, connections, and relationships between them. Schematics are essential for designing, building, and troubleshooting electronic devices, including computers, smartphones, and other complex systems.
