A device and a method for controlling a frequency of a CPU are provided to control the frequency of the CPU through the temperature of CPU to make a computer system operated by input current of a present adaptor even if the computer system is upgraded. A CPU(210) processes computation and controls functions. A current detector(260) measures the current supplied to the computer system. A frequency controller(250) controls an operation frequency of the CPU according to the measured current. A temperature controller(270) compares a preset current threshold with a measured current value, and enables a temperature sensor(240) to generate predetermined temperature information if the measured current is over the current threshold.
