RAR archive of about 1.66 MB covering the Lenovo ThinkPad L450 with motherboard NM-A351 at revision 1.0. The name does not say whether it holds a schematic, boardview or other data, so extract it to check. NM-A351 follows the LCFC (Lenovo) numbering used on ThinkPad boards. Revision-specific documents help with tracing power rails, finding test points and diagnosing shorts; because a 0.1 revision also circulates, verify that the revision printed on the PCB is 1.0 before relying on part values or net names.
