Lenovo schematic for the LCFC NM-C681 motherboard, revision 0.1, supplied as a PDF inside a 1.40 MB RAR. LCFC is Lenovo's own design and manufacturing arm, and it numbers its boards in the NM-xxxx style. The file name does not state the laptop model, so identify the unit by the number printed on the board. Use the drawings to trace rails, follow the power-on sequence and check the values around a suspected short. Revision 0.1 is an early draft, so verify details against the actual PCB.
