A 2.86 MB zip package labelled for the Acer Aspire V5-571 notebook. No board number, revision or document type appears in the name, so the actual contents, whether a schematic, a boardview or a firmware image, have to be checked after extraction. Acer commonly sources boards from ODMs such as Compal, Quanta or Wistron, and the same model can use more than one design. Match the PCB marking to whatever the files reference before tracing rails or flashing, and keep a dump of the original chip if you plan to reprogram 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 @laptopbios21. Enginerys does not host this file.
