PDF filed as a schematic for the ASUS G531GW, board revision 1.6, with BV in the name, which normally signals boardview material, so it may be a printable board layout rather than a circuit diagram. At 3.36 MB it can help locate components, test points and connectors on the main board when chasing a short or a missing rail. Open it in a PDF reader and search for designators. Confirm the revision 1.6 marking on the PCB before using placement or values for repair work.
