Schematic for the Microsoft Surface Book 3 Caravel top motherboard, packed as a PDF inside a 4.42 MB RAR archive. Extract it and open it in any PDF reader to trace power rails, check signal paths and component values, and find which parts sit on a shorted rail. Surface devices have dense, glued construction, so knowing the circuit before disassembly saves time. Confirm that the board in your unit is the top (Caravel) mainboard and not the base section before following the diagrams.
