Quanta G38D boardview file in .brd format, around 452 KB. The name gives only the Quanta project code, with no full board number, revision or laptop brand, so verify the code printed on your motherboard before using the layout.

Technicians use it to locate components named in a schematic, find convenient test points for measuring rails and narrow down which part is causing a short.
