Quanta board archive, revision 1A, labelled for the AMD Richland platform on the FP2 socket, which uses BGA-mounted APUs. No laptop model or Quanta project code is given beyond that, so identifying the right board relies on comparing the PCB marking with the schematic title block. The 785 KB RAR likely holds a schematic useful for tracing APU core and memory rails, checking the power sequence and locating components when diagnosing a short. Confirm the revision matches before trusting values.
