RAR package for the Quanta SWH board in its UMA version, revision 1A, meaning the variant using integrated graphics rather than a discrete GPU. The laptop model is not named, and the 1.06 MB archive most likely contains a schematic. On UMA boards the dedicated graphics power stage and VRAM are not populated, so use this file only for a board without a discrete GPU. It is handy for tracing power rails, checking sequence signals and finding test points; confirm the SWH code and 1A revision on the PCB first.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
