Second entry in a numbered series of RAR archives for the ASUS U80V laptop, about 124 KB in size. The file name says nothing beyond the model, so the type of material inside has to be confirmed after unpacking with WinRAR or 7-Zip. A size like this fits a boardview or a firmware dump better than a multi-page schematic. Make sure the PCB revision on your unit matches the data, and read out and back up the original flash chip before programming any image found in the archive.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
