Full schematic of about 23.9 MB for the Microsoft Surface Laptop 4 Intel version, Wayland board design. It is larger than the SS editions and is probably the complete circuit set. Use it to trace power rails from the charger through the PMIC and VRMs, check enable and power-good signals, and read connector pinouts for the display, keyboard and battery. Combine it with the Wayland boardview for physical locations. Make sure your unit is the Intel edition, since the AMD Laptop 4 uses a different board.
