A second copy of a 5.46 MB RAR archive for the Quanta LV6 motherboard, identical in name and size to another entry and likely the same package. The name states only the Quanta project code, which is the identifier this laptop ODM silkscreens onto its boards. Open the archive to find out whether it holds circuit diagrams, a boardview or other service data. Typical uses include tracing missing voltages, checking a shorted line against the diagram and locating test points, after confirming the PCB carries the LV6 marking.
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.
