Schematic package in RAR format for the Quanta U93U board, revision 1A, built around the AMD Kabini platform with UMA graphics, meaning video comes from the APU and there is no discrete GPU. The name does not state the laptop brand or model. The 532 KB archive is useful for tracing the APU core and memory rails, locating test points and diagnosing no-boot conditions. Quanta is an ODM producing boards for HP and others, and the same project code may exist in discrete-graphics variants, so confirm UMA layout and rev 1A on the PCB.
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.
