Schematic for the Quanta MA7 board, revision 3A, used in Gateway MX6920, MX6931, MT6840 and MT622b laptops, provided as a 1.12 MB PDF. The revision is stated, so compare it against the marking on the motherboard before trusting part values. Quanta's MA-series project codes identify the design shared across these models. Use the drawing for power-rail tracing, checking the charger and voltage regulators, and locating test points and connectors. Any PDF reader opens it, and the text can usually be searched.
