Abstract:
1. A circuit for a computer system, comprising: a pulse width module (PWM) module capable of converting a first voltage to a second voltage, the first voltage being capable of decreasing slower than the second voltage decreasing to have the PWM module entering in an unwanted state when the computer system is changed from a first state to a second state, the PWM module comprising a disabling pin capable of locking the PWM module when a voltage of the disabling pin is low; and a control circuit comprising a control pin connected to the disabling pin, a ground pin connected to ground, and a monitoring pin capable of monitoring the computer system being changed from the first state to the second state to control the control pin and the ground pin to pull the disabling pin low to lock the PWM module to prevent the PWM module from entering in the unwanted state.
