Abstract
Input/output (I/O) devices may be controlled to reduce power consumption of a computer system. A power consumption metric for the I/O devices connected to the computer system is determined. At least one of the I/O devices is selected based on the determined power consumption metric, and power consumption for the selected I/O device is reduced.
