The present disclosure relates to a system and method for health monitoring and early warning for an electronic device. A sensor is used to monitor a physical parameter of a circuit board of a host electronic system of the electronic device to acquire sensor data, and transmit the acquired sensor data to an embedded control device. The sensor data includes at least one of current data, vibration data, temperature data and voltage data. The embedded control device is used to extract a feature from the sensor data to acquire feature data, and perform real-time analysis and prediction based on the feature data to obtain and display a prediction result. In this way, the user can be provided with real-time health monitoring and real-time prediction information for the host electronic system circuit board.
