Boardview for the Lenovo laptop motherboard NM-A251, delivered in a RAR archive that the name says also includes a PDF. NM-xxxx codes follow the LCFC pattern used by Lenovo's own ODM, so the layout comes from the actual board manufacturer. A boardview reveals component positions, pin nets and test points, helping locate a shorted capacitor or check voltages around the charger or VRM. Open the layout in OpenBoardView or FlexBV, and make sure the number printed on the PCB is NM-A251.
