Schematic for the Lenovo ThinkPad T460s, motherboard NM-A581, packed as a RAR archive that holds the PDF diagram. The NM-A### numbering belongs to LCFC, the Lenovo-owned ODM that inherited the Compal-style codes. A technician uses it to follow power rails from the charger input through the system regulators, find the parts behind a short and check signal paths between chips. Confirm that the NM-A581 code printed on the PCB matches before trusting any reference designators or values taken from the diagram.
