PDF schematic, inside a RAR archive, for the Microsoft Surface Pro 6, with Madera as the project name, the Kaby Lake-R platform (KBL-R) and the part or board reference M1086941-003. Surface tablets are tightly packed, so the diagram helps follow the battery and charging path, the PMIC and VRM rails, and the display and connector signals when the device will not power on or charge. Check the board reference on the logic board against the one in the name before trusting pinouts or component values.
