Lenovo schematic in PDF, archived as RAR, for LCFC projects JS471 and JS573 on board NM-E541. LCFC, Lenovo's in-house ODM, labels its boards with the NM- prefix; the name does not state the laptop model or revision, so check the PCB first. The diagrams are used to follow power rails, check enable and power-good signals and identify components in a faulty circuit. Pair it with the matching NM-E541 boardview to locate the parts physically.
