Boardview for the ASUS UX32VD ultrabook mainboard at revision 2.4, compressed into a 384 KB RAR. The file shows both sides of the board with component outlines and net connectivity. That makes it handy for finding the parts in a power sequence, the charging circuit or a connector pinout during no-power and no-display repairs. A boardview program such as OpenBoardView or FlexBV opens the usual formats inside. Compare the revision silkscreened on the PCB with 2.4, because placement can change between board revisions.
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 @BoardSchematic. Enginerys does not host this file.
