Abstract:
1. A computer-implemented method for managing pulse-width modulation (PWM) in a host computer, the host computer comprising a PWM port and a powerGD port, the method comprising: periodically acquiring signals of the powerGD port; confirming a first state of the host computer corresponding to a first signal of the powerGD port; enabling the PWM port upon the condition that the first state is a power-on state; or disabling the PWM port upon the condition that the first state is a power-off state; confirming a second state of the host computer according to a second signal of the powerGD port; determining whether the second state is same as the first state of the host computer; enabling the PWM port according to the second state with the power-on state or disabling the PWM port according to the second state with the power-off state, upon the condition that the second state is different from the first state.
