Boardview for the Lenovo ThinkPad L540 motherboard, board number 12290-1, a five-digit code that follows Wistron's numbering. The compact RAR holds a layout file showing component placement and net connectivity, used to locate test points, follow power rails and find shorted capacitors. Common boardview viewers such as OpenBoardView or FlexBV open such files. Confirm that the 12290-1 marking on the PCB matches the file before relying on part locations.
