Second copy of the Surface Laptop 4 Intel Wayland SS schematic PDF, the same 10.5 MB size as the other file and likely a duplicate saved under a numbered name. It applies only to the Intel-based Laptop 4 motherboard. Use it as a reference for power rails, enable signals, PMIC connections and connector pin assignments when tracing a fault. Compare it with the full SCH document if pages or details seem missing, and verify the board design and edition before relying on part values.
