Archive for the LCFC CG510 board, numbered NM-A681 revision 0.2, used in Lenovo notebooks and packed as a 1.41 MB RAR. The name does not say whether it holds a schematic, a boardview or both, so check the contents after extraction. NM-xxxx numbers follow the LCFC pattern, the Lenovo-owned ODM formerly part of Compal. Such documentation helps with tracing power rails, locating components and test points, and finding shorts. Make sure the board revision printed on the PCB matches r0.2 before trusting part values.
