Power switch controllers and methods used therein are disclosed. An exemplifying power switch controller includes a window provider, a sensor and a logic controller. The window provider provides minimum and maximum time signals to indicate the elapses of a minimum time and a maximum time, respectively. The sensor detects a terminal of an inductive device, to generate a trigger signal. The logic controller prevents a power switch connected to the inductive device from being turned on before the elapse of the minimum time, forces the power switch to be turned on after the elapse of the maximum time, and turns on the power switch if the trigger signal is asserted.

A method and an electronic device for synchronizing information of dual operating systems and a recording medium are provided. The method is used for synchronizing information of a first operating system and a second operating system when an electronic device is switching from a first operating system to a second operating system. First, the second operating system sends an information requesting message to a controller of the electronic device when the first operating system is switched to the second operating system. The controller checks if the first operating system operates in a work mode. If the first operating system operates in the work mode, the controller forwards the information requesting message to the first operating system, so as to obtain the information of the first operating system. Finally, the second system synchronizes the information recorded therein according to the obtained information.

A system and an electronic device having multiple operating systems and an operating method thereof are provided. The electronic device includes a display and a system having a first operating system, a second operating system, and an embedded controller. The first operating system consumes less power than the second operating system. The embedded controller receives an input signal to switch between the first operating system and the second operating system and display an interface of the switched operating system on a screen of the display. The first operating system and the embedded controller remain in an alive state after the electronic device is turned on, and the second operating system enters a non-working state after a preset idle time.
