Abstract: An enclosure has an edge for defining a window opening. A keyboard is set in the window opening. A support member attached to the enclosure from the inside of the enclosure to receive the edge of the enclosure and the keyboard. A wall stands upright from the surface of the support member at a position outside the window opening. When coffee is spilled on the keyboard, the liquid flows into a space between the keyboard and the window opening. The surface tension of the liquid serves to prevent the liquid from immediately leaking outside the window opening through the gap between the edge and the support member. The liquid then starts leaking outside the window opening through the gap. The wall of the support member blocks the liquid. It thus takes a while before the liquid flows over the wall.
