Schematic for an HP Omen notebook mainboard numbered DAG3AAMBAF0, provided as a PDF; the name mentions a revision but gives no value. The DA prefix follows Quanta numbering, with G3A as the project code and the characters after MB indicating the board revision. Technicians use it to trace power rails feeding the CPU and GPU, check the power-good chain, read connector pinouts and locate parts on a shorted line. Confirm the full board number printed on the PCB, since Omen boards often exist in several revisions with different components.
