Archive for the Lenovo ThinkPad E470 built on the LCFC NM-A821 board, revision 2.0, in a 2.60 MB RAR. The name does not specify whether it holds a schematic, boardview or firmware, so inspect its contents. NM-xxxx numbering belongs to LCFC, the Lenovo-owned ODM that designs many ThinkPad and IdeaPad boards. Such material helps trace power rails, locate components and test points, or reflash the SPI chip. Make sure the PCB reads NM-A821 with revision 2.0 before relying on it.
