Lenovo schematic in PDF for the IQ3X0IL project on LCFC board NM-B511, revision 1.0. LCFC, Lenovo's own manufacturing arm, uses the NM-xxxx numbering for its motherboards. The diagram covers power rails, sequencing, charger and signal circuits, plus connector pinouts and component values for diagnosis. Any PDF reader will open it. Confirm the board number and revision printed on the PCB match before measuring against it, and pair it with the matching boardview.
