More Information
Summary:A computer device includes a microprocessor, a voltage converter circuit converting a first voltage of a system power into a second voltage, a control circuit controlling supply of the second voltage and a detection circuit detecting whether power abnormality at the peripheral device has occurred. When confirming that the system power is being supplied normally, the microprocessor generates a first enable signal to enable the voltage converter circuit. When confirming that the voltage converter circuit functions normally, the microprocessor generates a second enable signal to enable the detection circuit. The detection circuit generates a first detection signal according to detection result for the microprocessor to determine whether to supply the second voltage to the peripheral device. When the first detection signal indicates that power abnormality has not occurred, the microprocessor generates a third enable signal to enable the control circuit to supply the second voltage to the peripheral device.
