Boardview for the Lenovo motherboard NM-D741, provided in TVW format inside a 2.44 MB RAR archive. The NM-xxxx numbering is used by LCFC, the Lenovo-owned manufacturer of many IdeaPad and ThinkPad boards. TVW files open in Teboview or compatible viewers and show component locations, designators and nets. Technicians use it to track a short, find the PWM controllers and locate test points for rails. Verify the NM number printed on the PCB matches before relying on the placement.
