Schematic PDF for the Lenovo G580 built on Compal board LA-7981P. It documents the power rails, charger, CPU and memory circuits and connector pinouts, helping technicians trace missing voltages, find shorted components and follow the power-on sequence. Opens in any PDF viewer. The name does not state a revision, so compare the board number and revision on the PCB with the schematic title block before relying on specific values.
