Boardview for a Lenovo laptop mainboard built by LCFC, board number NM-B721 at revision 1.0, packed as an 11.3 MB ZIP archive. The name gives no consumer model, so identify the machine by the silkscreen on the PCB and confirm it reads NM-B721 REV1.0 before trusting the layout. NM-prefixed numbers follow the LCFC scheme, the Lenovo-owned ODM. After extraction the board file opens in a viewer such as OpenBoardView, FlexBV or Boardviewer, where you can search nets, locate components and find test points while chasing a short or missing rail.
