Boardview for Lenovo mainboard NM-E401, revision 1.0, under project code JS574, in a 2.20 MB RAR archive. NM- numbers follow the LCFC scheme, the Lenovo-owned ODM behind many of its notebooks, though the exact laptop model is not named. A viewer such as FlexBV or OpenBoardView shows part placement and net connectivity, which helps when checking rails, locating fuses and coils or isolating a shorted capacitor. Confirm the NM-E401 silkscreen and revision 1.0 on the board first, since another revision may differ in layout.
