Abstract: A method for controlling a central processing unit (CPU), where the method includes: acquiring a usage rate and an operating frequency of one CPU of operating CPUs; if the operating frequency of the one CPU is smaller than a core off-line frequency, multiplying the usage rate of the one CPU by a first weight to obtain a CPU power consumption sensitive factor corresponding to the one CPU; if the operating frequency of the one CPU is greater than or equal to the core off-line frequency, multiplying the usage rate of the one CPU by a second weight to obtain a CPU power consumption sensitive factor corresponding to the one CPU; and turning off at least one operating CPU if the mean is smaller than a CPU turn-off power consumption sensitive factor threshold.
