Schematic PDF of 1.31 MB with the label AW3 MB-0315, which gives no brand, laptop model or recognisable board number beyond that code. The 0315 may be a date or version, but that cannot be confirmed from the name. Use it like any circuit diagram to trace voltage rails, follow the power-on sequence and identify components near a fault. Open it in a PDF reader and compare the title block and board markings with the PCB on the bench before relying on it.
