Lenovo laptop schematic for board NM-A272, revision R1.0, labelled Compal and packed as a 2.06 MB RAR archive. NM-xxxx numbering is used by LCFC, the Lenovo and Compal joint venture that builds many Lenovo notebooks, so it is the board maker's code rather than a retail model name. The diagram is used to trace power rails and signals, check regulator outputs and locate a shorted part. Confirm the PCB reads NM-A272 with matching revision before relying on it.
