Wistron schematic for the Brian project, board 14074-1 with 14074-SA also referenced, delivered as a PDF inside a 1.88 MB RAR archive. Wistron designs motherboards for several laptop brands under such project names and five-digit codes. The diagrams let a technician follow power rails, charger and EC circuits, and the power-on sequence when diagnosing a faulty board. Open the extracted PDF in any reader, and pair it with the matching boardview after confirming the code and revision on the PCB.
