Small RAR archive of 2.31 KB for board 08627-SA. No brand, model or confirmed numbering scheme is given, though the SA suffix resembles Wistron-style naming. Such a small file cannot contain a schematic or full boardview and may be a note or incomplete archive; a 47.8 KB upload under the same number is more likely usable. Extract it to inspect the content, and verify your PCB reads 08627-SA rather than 08627-1 before relying on related material.
