Lenovo motherboard schematic for Compal/LCFC board NM-A181, revision 1.1, as a 1016 KB PDF. The laptop model is not named, so confirm by reading the NM-A181 marking on the PCB itself; NM-prefixed numbers follow the numbering used on Lenovo boards from Compal and LCFC. Use the drawing to trace main and standby power rails, verify charger behaviour, follow embedded controller and PCH signals and pinpoint the component behind a short circuit. It opens in any PDF viewer, and net-name searching makes locating rails quicker.
