PDF schematic for the Lenovo Y700 on the LCFC NM-A541 motherboard, revision 1.0, with BY511 as the project code. LCFC uses NM- numbers for Lenovo main boards, and the matching boardview will help you locate parts physically. The diagrams show power-rail generation, power-on sequencing, charger and VRM circuits and connector pinouts, which makes them the main reference for diagnosing no-power or no-display faults. Check that the NM-A541 number and revision on the PCB match before you compare measurements.
