Abstract
An electronic device includes a foldable screen, a first sensor, a security chip, a control module, and a first functional component. The first sensor, the security chip, and the control module are directly or indirectly connected through a circuit wire. The control module is configured to control the first functional component to be disconnected from or connected to a power supply. The first sensor is configured to detect a first operation of a user. The first sensor is further configured to send first sensor data to the security chip based on the first operation, where the sensor data indicates a posture of the electronic device. The security chip is configured to send a first control instruction to the control module based on the posture indicated by the first sensor data.
