Quanta LV6 archive in RAR format at 5.46 MB, named only by the project code, so the exact contents, schematic, boardview or both, must be checked after extraction. Quanta uses short codes like LV6 to identify laptop mainboard designs, and the code is typically printed on the PCB together with a DA-series number and revision. A schematic from such a set lets you follow power sequencing and rails, while boardview data pinpoints components. Match the code and revision with your board before working from it.
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 @schematicslaptop. Enginerys does not host this file.
