Small RAR archive for the ASUS BU201LA, version or revision 1.1 as indicated in the name; its exact contents are not listed, though the 132 KB size suits a boardview or similar repair data rather than a full schematic. Extract it with WinRAR or 7-Zip and check what is inside. If it holds a boardview, open it with a viewer such as OpenBoardView or FlexBV to locate components, test points and nets. Check that the board revision on the PCB corresponds to 1.1 before trusting part placement.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
