A power switching circuit of a portable electronic device is disclosed. The portable electronic device can be coupled to an expansion device. The power switching circuit includes a first power terminal, a second power terminal, a first switch module, a second switch module, and a power pin. The first switch module is coupled to the first power terminal. The second switch module is coupled to the second power terminal. The power pin is coupled to the first switch module and the second switch module, respectively. When the portable electronic device is not coupled to the expansion device, the first switch module and the second switch module are turned off, such that first power provided by the first power terminal and second power provided by the second power terminal fail to be provided for the power pin via the first switch module and the second switch module.

Power switching circuit of portable electronic device

This invention provides an electronic device and a power control module thereof. The electronic device is used for being connected with an external power source, and the electronic device includes a system unit, a power supply unit, a power control module, and a control unit coupled with the system unit and the power control module. When the power supply unit is connected with the external power source, the power supply unit provides a first operating voltage for the power control module, the power control module provides a first control signal for the control unit, and the control unit receives the first control signal and provides a second control signal for the power supply unit according to the first control signal, allowing the power supply unit to sequentially provide a plurality of system working voltages for the system unit.

Electronic device and power control module for controlling a starting process of the electronic device utilizing a delay latch circuit and an inverse logic unit

This invention provides a peripheral control module, a computer system, and an operation method thereof. The peripheral control module is for a computer system. The computer system includes a power switch capable of outputting a power signal. The peripheral control module includes a control unit and a control circuit. The control unit has a program code for controlling a peripheral module. The control circuit is coupled with the power switch and the control unit for receiving the power signal and outputting a switching signal to the control unit, and the control circuit resets the program code to an initial state before the control unit receives the switching signal. This invention further provides a computer system using the peripheral control module and an operation method thereof.

Peripheral control module, computer system, and operation method thereof

This invention discloses an electronic device with a heating protection circuit and a heating protection method thereof. The electronic device includes a control module, a heating protection circuit, a heating switch module, and a heating module. The control module provides a first control signal and a second control signal via a plurality of control pins, respectively. The heating protection circuit generates a third control signal according to the first control signal and the second control signal. The heating switch module controls the heating module whether to heat according to the third control signal.

Electronic device with heating protection circuit and heating protection method thereof

The invention discloses a method for protecting data in a non-volatile storage device and a computer thereof. The computer includes a non-volatile storage device, a temperature sensing unit, and a controller. The temperature sensing unit is disposed at the non-volatile storage device to sense a sensed temperature of the non-volatile storage device and to compare the sensed temperature with a predetermined temperature. The controller is coupled with the temperature sensing unit. When the sensed temperature is higher than the predetermined temperature, the controller makes the computer enter into a hibernation state.
