LCFC schematic for the Lenovo ThinkPad E470 mainboard NM-A821, revision 2.0, delivered as a 2.73 MB PDF. LCFC, the Lenovo-owned manufacturing arm formerly linked to Compal, numbers its boards with the NM-xxxx pattern. A technician can use it to trace the adapter input and battery charger, the system rails, embedded controller signals and the power-on sequence, and to look up component designators and values. Check that the board number and revision on the PCB match rev 2.0, since earlier or later revisions may differ in parts.
