Quanta R23 motherboard schematic in a 900 KB PDF, matching the size of other R23 copies. The bracketed text in the name is only a source tag from a technician website, not a model detail, and no revision or brand is stated. R23 is a Quanta project code, and Quanta designs boards that other laptop brands sell, so match the code on the PCB silkscreen. Use the document to follow power rails, check component values, trace signals between ICs and locate shorted parts. Any PDF viewer opens it, and the title block should show the revision to compare.
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 @abgm_manutencao_esquemas. Enginerys does not host this file.
