LCFC boardview for Lenovo motherboard NM-D352, revision 1.0. The name gives no laptop model, so identify the unit by the NM number printed on the PCB, which is the standard numbering used by LCFC, Lenovo's in-house board maker. It comes as a 2.55 MB RAR archive. Load the file into a boardview viewer to find components by designator, follow power rails and signals and pick test points when looking for a short or a missing rail. Confirm the revision matches.
