Lenovo G40 schematic for Compal board NM-A271, covering the ACLU1 and ACLU2 designs, as a 1.25 MB PDF. ACLU1 and ACLU2 are the project codes listed for this board, which may correspond to different platform variants, so check which pages apply to your unit. NM numbering is the Compal/LCFC scheme used for Lenovo laptops. The drawings support tracing power rails, checking the charger, following embedded controller signals and isolating shorts. Verify the number printed on the PCB reads NM-A271 before relying on it; any PDF viewer opens it.
