Lenovo board package for LCFC motherboard NM-A311, described in the name as a PDF together with a boardview. NM-xxxx is the numbering LCFC, Lenovo's own ODM, uses for notebook boards. The boardview shows component placement, net names and pin connections, and opens in viewers such as OpenBoardView, FlexBV or Boardviewer. The 157 KB RAR is small, so check what it actually contains. Use it to locate test points and parts on a shorted rail, after confirming the NM-A311 marking on the PCB.
