Schematic PDF for the UX410UQ notebook, with the extra tag RG in the name, about 1000 KB in size. The name gives no board revision, so read the title block to confirm which version of the main board is drawn. Any PDF viewer opens it, and technicians use it to follow power rails from the charger input onward, check voltage regulator circuits, find test points and work out which component pulls a line to ground. Match the revision on the PCB to the sheets before trusting part values.
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 @ithinkhs_casediscussion. Enginerys does not host this file.
