Lenovo ThinkPad E490 schematic for board NM-B911, SVT build stage, dated 14 September 2018, about 5.79 MB. The NM prefix marks an LCFC mainboard design. SVT refers to system validation testing, a late pre-production phase, so most values should match retail boards but small differences are possible. Technicians use it to trace power rails, follow the startup sequence, check charger and EC signals and identify component values. Confirm the board number on the PCB is NM-B911 and pair the sheet with a boardview to locate parts.
