Schematic for the Microsoft Surface Pro 5, board M1007506-015 at revision U23, delivered as a PDF. Technicians use these diagrams to follow power sequencing, locate the components on a shorted rail and verify signal connections for the display, charging port and battery. Open it in any PDF reader and search for net names to move between pages. Before relying on it, check that the revision on the logic board reads U23; the earlier U22 schematic may suit boards of that revision better.
