Boardview for the Wistron-designed GHIBLI laptop board 18803-1, also marked 0GY02, supplied in BDV format inside a RAR archive. BDV files open in boardview viewers such as FlexBV and similar tools that support the format. With it you can locate components, test points and connectors, and follow nets to find where a power rail is shorted. Wistron numbers of this five-digit pattern are usually printed on the PCB, so confirm 18803-1 matches your board before relying on any location.
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 @pkbiosbdv. Enginerys does not host this file.
