Schematic diagram for the LCFC NM-A321 motherboard, revision 1.0, a compact 879 KB PDF for a Lenovo notebook whose model the file name does not state. LCFC, Lenovo's Compal-founded design house, uses the NM- board numbering seen here. The sheets help when tracing standby and main power rails, checking the EC and BIOS circuitry, or locating a shorted capacitor. Read the board number on the PCB first, because similar NM- numbers belong to entirely different laptops.
