Boardview in BDV format for the LSN-3 SWG MB H0226-2 board, known from related files as the ThinkPad T420s mainboard, packed as a 390 KB RAR. The name itself gives no laptop model or revision beyond the board code. BDV files open in viewers such as OpenBoardView, FlexBV or Boardviewer and show part positions, pins and nets on both sides. They help you locate test points, follow a signal to its source, and isolate a component shorting a rail. Check the board identifier on your PCB.
