Mainboard boardview for NM-F331 revision 1.0, in TVW format inside a 3.16 MB zip archive. The NM- numbering follows the LCFC pattern, the Lenovo-owned ODM that builds many IdeaPad, ThinkBook and Legion boards. With the layout open in a TVW-capable viewer you can locate components by reference designator, follow nets between parts, find test points for power rails and check where a short to ground may sit. Match the NM-F331 code and revision printed on the PCB before relying on part locations.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @vinafix_bios. Enginerys does not host this file.
