Archive for a Lenovo laptop on Quanta board DA0PS8MB8G0, revision G. Quanta uses the DA0 prefix followed by the project code, here PS8, with the rev letter printed on the PCB. The 37.2 MB ZIP does not state its contents, but packages of this size usually hold a schematic, boardview or both, used to follow power rails, identify parts and find test points. Confirm the project code and revision letter on the board before trusting component layouts from these files.
