Boardview for a Lenovo laptop mainboard numbered NM-E691, revision 1.0, an LCFC design, since the NM- prefix is the numbering used by LCFC, Lenovo's Hefei manufacturing unit. The 8.18 MB zip is large for a boardview and may hold extra files alongside the layout. A viewer such as OpenBoardView or FlexBV shows component positions, nets and test points for diagnosing shorts or missing rails. The name gives no laptop model, so confirm NM-E691 and the revision printed on the PCB before use.
