Schematic PDF for an HP laptop mainboard, Quanta board DA0R75MB6C1, packed as RAR. The model name is not given beyond HP and the board number, and the C1 suffix marks the PCB revision. Quanta uses the DAxxxxMBxxx board-numbering pattern for the boards it builds for HP. The drawings help trace power rails, check the charging circuit and find parts behind a short. Check the number printed on the PCB before use, and open the extracted file with any PDF viewer.
