Schematic for the Lenovo ThinkPad X270 in PDF format, about 3.11 MB, tagged NM-B061 with an R04 suffix that appears to mark the board revision. The NM-xxxx pattern is the one used by LCFC, the Lenovo design house. Use it to trace voltage regulators, find the source of a short to ground, confirm the power-on sequence and locate test points on a board that will not start. Check the number and revision printed on the PCB before relying on part values, because ThinkPad boards often change between revisions.
