Schematic in PDF for a board code-named IRIS BSW, number 14279-1, 4.19 MB. The five-digit-dash numbering follows the Wistron pattern, so Wistron is the ODM; BSW most likely refers to the Intel Braswell platform, though the name gives no laptop model. A schematic shows the full circuit, so it is used to trace power rails, follow enable and power-good signals and identify parts on a faulty line. Verify the board number printed on the PCB matches 14279-1 before relying on it.
