Duplicate of the Compal NM-A181 rev 1.1 schematic for a Lenovo notebook, stored as a 1016 KB PDF. The NM-A number follows the Compal/LCFC scheme used on Lenovo boards, though the specific laptop model is not stated, so the board marking on the PCB should be checked first. The pages help in following power distribution from the adapter input, reading signal names between the chipset and embedded controller, diagnosing charger faults and tracking down short circuits. Open in any PDF viewer and compare revisions before trusting part values.
