Compressed boardview for the Microsoft Surface Laptop 4; the name points to the Wayland board design and a 5k-related revision code, rev 10. The ZIP is about 613 KB and most likely contains a PCB-format layout. Open it with a boardview program such as FlexBV or OpenBoardView to locate components, follow nets between both sides of the board and identify test points. Surface boards are densely packed, so the layout helps a lot when probing rails under shields. Check the board markings match before use.
