Abstract
A portable computer comprising a digital broadcasting reception module having a digital broadcasting receiving part and a digital broadcasting processor to process digital broadcasting signals received through the digital broadcasting receiving part and a power supply to supply power to drive the digital broadcasting receiving part and the digital broadcasting processor. A controller controls a mode of power supplied to the receiving part and the processing part according to an initialization routine of the portable computer, according to whether an adaptor is supplying the drive power, and according to a user input. The user may set the initialization routine according to whether the user normally desires to use the broadcasting receiving part and may vary the power mode using an input window of the portable computer, to conserve power according to whether the drive power is being operated from an adaptor or from a battery.
