Archive for board 11297-1 with the label LCO-2, packed as a 1.58 MB RAR file. The number follows the Wistron pattern of a five-digit project code with a revision suffix, but the laptop brand and model are not named, and neither are the contents. Extract it to check whether it holds a schematic, boardview or BIOS. Such files are used to trace power and signal paths, locate components and diagnose shorts. Verify that the number printed on the motherboard matches 11297-1 before relying on any values.
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 @cyberlanelectonik. Enginerys does not host this file.
