Lenovo EX480 board documentation in a 3.80 MB RAR archive, board number NM-B481, revision 1.0. NM numbering belongs to LCFC, the Lenovo-controlled ODM that designs and builds many ThinkPad and IdeaPad boards. The name does not detail contents, but such archives usually contain a schematic and possibly boardview files for tracing rails and locating parts. Use them to check power sequencing, find test points and diagnose shorts. Unpack the archive, then confirm the NM-B481 label and revision on the motherboard before relying on it.
