Boardview for the HS450 project on LCFC board NM-D231, the Lenovo Yoga 14s family, in .TVW format inside a 977 KB RAR archive. The name gives no revision, so check what is printed on the PCB before tracing. NM-xxxx is the LCFC numbering pattern used on Lenovo laptops. TVW layouts open in TVW-compatible viewers or FlexBV and show component placement and net connections, making it easier to locate a shorted capacitor, find the PWM controller for a rail or probe test points with a multimeter.
