Archive for Lenovo board NM-A221, project AITE1, revision 1.0, dated 2014-08-07, roughly 12.2 MB. NM-prefixed numbers come from LCFC, the ODM behind many Lenovo laptops. The name does not list the contents, which commonly include a schematic and possibly a boardview, so unpack and check. Such material helps a technician understand power-on sequencing, follow rails from the charger IC to the CPU VRM and find components during repair. Confirm that the PCB silkscreen reads NM-A221 Rev 1.0 before relying on it.
