Schematic PDF for the Microsoft Surface Pro 5 tablet logic board; the file name gives no board number or revision. Circuit diagrams of this kind help a technician follow the charging circuit, battery connection, power rails and display signals when repairing no-power or no-image faults. Because the revision is not stated, check the title block inside the document and compare it with the number printed on the board. Other Surface Pro 5 schematics carry the board number M1007506-015 with specific revisions, worth comparing.
