Boardview for the Lenovo IdeaPad 3-17ADA05, board NM-C821 at revision 0.2, archived as RAR at 763 KB. The NM-xxxx numbering is used by LCFC, the Lenovo-owned ODM that builds many IdeaPad boards. A boardview shows component placement, net names and test points, letting a technician locate a shorted capacitor, follow a rail between parts and measure signals. Open it in viewers such as OpenBoardView or FlexBV, and confirm the NM-C821 label and revision on the PCB before relying on it.
