PDF schematic for the Lenovo G480 laptop on Compal mainboard LA-7981P. No revision or project code appears in the name, so check the title block inside the document against the revision marked on your board. Compal assigns LA-xxxxP numbers to its notebook mainboards, and this board number is also associated with the G580 family. Use the diagram to trace rails from the DC jack and charger through the system regulators, check the EC and power-sequence signals and identify components when locating a short.
