Boardview for the Lenovo IdeaPad 3-17ADA05 mainboard NM-C821 revision 0.2, in a compact 763 KB RAR archive. NM-xxxx numbers belong to LCFC, Lenovo's own design and manufacturing arm. Open it in a viewer such as OpenBoardView or FlexBV to locate components, probe test points, trace nets between connectors and narrow down which part shorts a rail. Since one board number can cover several models and revisions, confirm that your PCB shows NM-C821 at the same revision before relying on part placements.
