RAR archive of 47.9 KB for board 09513-SB, the larger of two uploads with this number and therefore the more likely to hold usable data such as a boardview. The name does not state brand, model or contents, and the scheme is unconfirmed, though the SB suffix resembles Wistron naming. Extract it and open any layout file in a boardview viewer to locate parts and test points. Check the PCB silkscreen matches 09513-SB before using it in diagnosis.
