A drying apparatus includes a humidity sensor module, a micro control unit (MCU) module, an indicator circuit, and a fan module. The humidity sensor module measures relative humidity of air in a computer, and converts that measurement to an electronic signal. The MCU module receives the electronic signal from the humidity sensor module, and respectively outputs an indication signal and a control signal when the measured humidity is greater than a predetermined value stored in the MCU module. The indicator circuit indicates the humidity in the computer is too high when it receives the indication signal from the MCU module. The fan is activated when it receives the control signal from the MCU module.
