Schematic in PDF for Compal board LA-H451P, revision 1.0. The name gives no laptop brand or model, so identify the target by the number printed on the PCB. A schematic shows the power rails, the enable and power-good signals, connector pinouts and component values. That lets a technician work through no-power, no-boot or charging faults stage by stage. Any PDF reader opens it, and the searchable net names help when cross-referencing with a boardview. Make sure the board revision matches before trusting values.
