Second copy of a .gr boardview for board 10260-1, same 304 KB size as the other listing and likely a duplicate saved under a numbered file name. The number matches the Wistron project scheme, so the laptop brand itself is not stated here. Load it in OpenBoardView or a similar viewer to locate components, probe nets and trace power rails during diagnosis. Compare with the other copy if one fails to open, and confirm the PCB marking matches 10260-1 before using the placement data.
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 @one5technology. Enginerys does not host this file.
