Compal LA-6751P documents tied to the G570 and G470 models, compressed as a 971 KB RAR. LA-6751P follows Compal numbering, and the model names suggest the Lenovo G-series consumer laptops built on this board. Confirm the board number and revision printed on your PCB before relying on the material. Use the schematic to trace rails from the DC jack, measure voltages at test points, check the EC and SPI flash area, and track down shorted capacitors or failed regulator MOSFETs.
