The invention provides a method, an element and a circuit board for controlling an electronic device to be shut down. The method according to the invention includes the steps as follows. First, a power control signal is received, and the duration of the power control signal at a preset signal level is calculated. Then, whether the duration is greater than a threshold value is determined. If yes, an interrupt signal is generated and transmitted to a processing module of the electronic device to drive the processing module to set the preset mechanism of the electronic device according to the interrupt signal. |
