PDF schematic for the Lenovo ThinkCentre M70q Gen2 tiny desktop, board NM-D331 version 1.0, also labelled TINY7 MB HB560. NM- numbers belong to the LCFC scheme used on Lenovo-manufactured boards. The 9.74 MB document covers the circuitry a technician needs to trace power rails from the DC input, check voltage regulators and follow signals to ports and the SPI flash. Any PDF reader opens it. Ensure the PCB carries NM-D331 rev 1.0 before trusting component values.
