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.
Claims34
A method of selecting input/output (I/O) devices to control power consumption of a computer system, the method comprising:
- determining a power consumption metric for each of a plurality of I/O devices connected to the computer system;
- selecting at least one of the plurality of I/O devices based on the determined power consumption metric;
- and
- reducing power consumption of the at least one selected I/O device.
A method of controlling power consumption of I/O devices for a computer system, the method comprising:
- profiling usage patterns of the I/O devices to establish a usage model;
- identifying low-power alternatives to using at least one of the I/O devices using the usage model;
- profiling power consumption of the I/O devices to establish a power model;
- selecting at least one of the low-power alternatives to reduce power consumption of the computer system based on the power model.
An apparatus comprising:
- means for identifying a plurality of low-power alternative means to using an I/O device connected to the computer system using a usage model;
- and
- means for selecting at least one of the low-power alternatives means to reduce power consumption of the computer system using a power model.
Computer software embedded on a computer readable medium, the computer software comprising instructions of:
- determining a power consumption metric for each of a plurality of I/O devices connected to a computer system;
- selecting at least one of the plurality of I/O devices based on the determined power consumption metric;
- and
- reducing power consumption of the at least one selected I/O device.
A computer system comprising:
- a processor;
- and
- a battery, wherein the processor is operable to determine a power consumption metric for each of a plurality of I/O devices connected to the computer system, select at least one of the plurality of I/O devices based on the determined power consumption metric, and control the at least one selected I/O device to reduce power consumption in response to remaining battery life falling below a threshold.
