RAR archive holding a PDF schematic for the LCFC NM-D522 motherboard, revision 0.2, an AMD-based design according to the name. LCFC is the Lenovo-owned manufacturer whose boards carry NM-xxxx numbers, so this belongs to a Lenovo notebook, though the model is not named here. Use it to trace power rails, check the startup sequence and identify parts on shorted lines. Rev 0.2 suggests an early engineering release, so compare the board number and revision printed on the PCB and expect some component values to differ from production.
