Apple schematic for the A2179 MacBook Air, logic board 820-01958, with X1783 noted in the name, likely the internal project code. The 820- prefix is Apple's own board numbering, and the full number on the logic board must match before you trust the drawing. Technicians use it to follow power rails from the USB-C input, check the sequencing of the main supplies, locate the source of a short and identify signal paths. It is a PDF, readable in any viewer with text search for net names.
