Boardview for the HP Stream 14, board number DA0P9MB16D0, packed as a RAR archive of about 1 MB. The DA0 prefix follows the Quanta numbering scheme, so the P9 project is a Quanta design, with MB marking the mainboard. A boardview maps component outlines, designators and nets, which lets you jump from a schematic reference to the physical part, find test points, and check which components share a shorted rail. Open it with OpenBoardView, FlexBV or a similar tool, and match the board revision before use.
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 @alischematics. Enginerys does not host this file.
