Schematic for the Lenovo ThinkPad E14 and E15 Gen 2 with the AMD Renoir platform, board NM-C771 revision 0.2, provided as PDF inside a 1.62 MB RAR archive. NM-xxxx codes come from LCFC, Lenovo's own manufacturing arm. The diagram helps trace power rails, the power on sequence, charging circuitry and signal paths during board level repair. Revision 0.2 suggests an early document issue, so compare component values and the board marking with the actual PCB. Opens in any PDF reader after extraction.
