Circuit schematic for the Quanta NE7 board, revision 3A, in a 1.34 MB PDF. The file name gives no laptop brand, chipset or graphics configuration. A schematic like this is used for tracing voltage rails from their regulators, checking the power-on sequence driven by the embedded controller, measuring at test points and locating shorted components. Several NE7 copies exist in this index with similar sizes, so compare them if a page is unclear. Confirm the NE7 code and Rev 3A on the physical PCB before trusting component values.
