ZIP archive of 162 KB tied to the ASUS U80V notebook. The file name gives only the model, with no board revision or content type, so it should be opened and checked before use. At this size it most likely contains a boardview, a firmware dump or a partial set of service documents rather than a full schematic package. Whatever is inside, compare the board markings printed on your PCB with those in the files, and if a BIOS image is present, back up the original SPI chip with a programmer before writing anything.
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. Enginerys does not host this file.
