A further PDF copy of the Quanta MA2 motherboard schematic at revision 2A, 2.15 MB in size and apparently identical to the other MA2 files. The name carries only the ODM code and revision, with no retail model. Before using it, read the project code and revision printed on the PCB, since Quanta reuses board families across brands. The schematic supports fault finding: tracing the adapter and battery input, checking the charger and regulator outputs, finding test points and following signals to the BIOS flash chip and the embedded controller.
