Schematic for the Lenovo ThinkPad E490 with board NM-B911, revision 0.4, supplied as a PDF inside a 5.81 MB RAR archive. NM-xxxx numbers follow the LCFC scheme, Lenovo's own ODM. The diagrams let a technician trace power rails, check the power-on sequence and locate components involved in charging or no-boot faults. Open in any PDF reader. Revision 0.4 indicates an early design stage, so component values or placement may differ from production boards; compare with your PCB before relying on details.
