Boardview in CAD format for the LCFC motherboard NM-A831, with revision 20 noted, packed as a 324 KB RAR. LCFC is the Lenovo-owned ODM, so this board belongs to a Lenovo laptop, though the model is not named. CAD boardview files open in viewers like OpenBoardView, FlexBV or Boardviewer, showing part placement, nets and test pads. Use it to locate components on rails while measuring or hunting shorts, and confirm the NM-A831 code and revision on the PCB first.
