PDF schematic in a RAR archive for an HP laptop mainboard made by Quanta, project UT1A, board number DAUT1AMB6D0. Quanta assigns DA...MB... numbers to boards it builds for HP and other brands. The diagram is used to trace power rails from the adapter input through the charger and system regulators, check signal connections and find components related to a no-power or short fault. Confirm the board number and revision printed on the PCB, as differing revisions can change part references and circuit details.
