Lenovo ThinkPad T470p motherboard schematic for board NM-B071. The NM- prefix belongs to the LCFC numbering scheme, Lenovo's Hefei manufacturing joint venture with Compal, whose designs follow Compal-style documentation. Technicians use it to trace power rails, follow the charger and EC circuits, find the BIOS flash chip and identify components on a shorted line. Check that NM-B071 is printed on the board before working from it. The PDF opens in any reader and supports searching net names.
