PDF schematic, 1.14 MB, covering the Quanta-made notebook mainboard DA0LZ7MB8E0, project code LZ7. Quanta stamps this DA0 plus project plus MB plus revision code on its boards, and the laptop brand that sold the machine is often different. The diagrams let you follow power sequencing from the charger input through the main rails, check enable and power-good signals and identify parts around a suspected short. Before using it, compare the full board code on your PCB, since a different revision can change components.
