A very early R0.03 schematic of the Compal LA-7552P board, delivered as a 1.02 MB RAR archive. The name identifies neither the notebook model nor its brand, only the board number used by Compal, the Taiwanese ODM. Such a low revision is an early draft, so expect differences from shipped boards in part placement or values; a later R0.1 set of the same board also exists. Extract it and use the diagrams to trace rails, enable lines and the charging circuit when diagnosing no-power or short faults. Confirm the PCB revision first.
