Compal schematic for board LA-4105P used in an HP laptop, a 1.48 MB PDF. The name gives no exact HP model, so identify the board by the number printed on the PCB. Compal uses this LA-xxxxP pattern for boards made under contract for laptop brands. The document helps with tracing power rails, checking the charging and power-on circuits and locating components by reference designator. Confirm the revision on your board, since differences between revisions can change parts and values.
