Schematic in PDF for the Compal LA-B181P board, revision 0.5, with LA-B171P also listed in the catalogue data, in a 2.56 MB RAR. The name gives no laptop brand or model, so identify the unit by the board number printed on the PCB. LA-xxxxP is Compal's numbering pattern. Use the diagrams to trace power rails, the charging circuit and the sequencing signals, and note that 0.5 is a pre-production revision that may differ from the final board.
