Claim Text:
1. A computer system, comprising: a device which operates according to a clock frequency; a battery unit, which comprises a plurality of battery cells, for supplying power to the device; a temperature sensor provided at a location outside of the battery unit for detecting a temperature of the battery cells; a current sensor coupled to the battery unit for detecting a value of a current supplied from the battery unit to the device; a comparator configured to compare the detected temperature with a first reference value or the detected current value with a second reference value; and a controller configured to decrease the clock frequency if the detected temperature is greater than the first reference value or if the detected current value is greater than the second reference value, wherein the comparing of the detected temperature with the first reference value comprises converting the detected temperature to a first voltage level, wherein the comparing of the detected current value with the second reference value comprises converting the detected current value to a second voltage level, and wherein the first reference value and the second reference value which are input to the comparator comprise a same reference voltage level.
