Boardview for a mainboard identified as PT10S, UMA version (integrated graphics only, no discrete GPU), revision 2.1, packed in a 131 KB RAR archive. The name does not state the laptop brand, so confirm the PT10S marking and Rev 2.1 on the PCB silkscreen before use. After extracting, open the layout in a viewer such as OpenBoardView, FlexBV or Boardviewer to locate components, follow nets between parts, find test points and check where a shorted rail leads when diagnosing no-power faults.
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 @boardview. Enginerys does not host this file.
