Schematic for the Compal LA-4853P laptop mainboard, revision 1, in an 826 KB PDF. Apart from the board code and revision, the name says nothing about the laptop brand or model. Compal identifies its ODM motherboard designs with LA-xxxxP numbers printed on the PCB. The document is handy for following power rails from the DC jack and charger through the regulators, checking enable signals and locating the components on a shorted line. Verify the board number on the PCB matches before using the diagram.
