Schematic in PDF form, packed in a RAR, for LCFC board NM-A403 at revision 1.0, a Lenovo laptop motherboard; the laptop model itself is not named. LCFC, Lenovo's own manufacturer, uses this NM- numbering. The schematic shows power rails, the power-up sequence, connector pinouts and component values, letting a technician trace a missing voltage or signal. It pairs naturally with an NM-A403 boardview; make sure the board number and revision on the PCB match revision 1.0.
