Abstract
An apparatus may comprise a power management system. Other embodiments are described and claimed.
Claims19
An apparatus, comprising:
- a device platform comprising a first device and a second device, the first device and the second device each arranged to operate in multiple power modes, the first device comprising a processor with multiple cores, the second device comprising one or more of a processor having a graphics core, an I/O device, a graphics controller, a memory, a wireless communication device, an I/O device controller, or display electronics;
- and
- a power knob comprising a user interface element arranged to provide multiple power mode selections for the first device and the second device, the multiple power mode selections to include at least one low power mode in which the first device and the second device operate at a lower power than in a high power mode and in which at least a first one of the multiple cores is to operate under a first operating mode and at least a second one of the multiple cores is to operate under a second operating mode while the low power mode is selected, the first operating mode different than the second operating mode.
A system, comprising:
- a first device and a second device in a device platform each of the first and second devices being configurable to operate in multiple power modes, wherein the first device comprises a processor with multiple cores and the second device comprises one or more of a processor having a graphics core, an I/O device, a graphics controller, a memory, a wireless communication device, an I/O device controller, and display electronics;
- and
- a power management module that includes a knob comprising a user interface element arranged to provide a selection of at least one low power mode in which the first and second devices are to operate at a lower power than in a first power mode and in which a first one of the multiple processor cores is to operate under a first operating mode and a second one of the multiple processor cores is to operate under a second operating mode while the low power mode is selected, the first operating mode different than the second operating mode.
An article comprising a non-transitory computer-readable storage medium containing instructions that if executed by a processor enable a system to:
- receive a selection of a low power mode of operation for a first device and a second device in a device platform from a knob comprising a user interface element arranged to provide a selection of the at least one low power mode in a system that is arranged to operate in multiple power modes, the first device comprising a processor with multiple cores and the second device comprising one or more of a processor having a graphics core, an I/O device, a graphics controller, a memory, a wireless communication device, an I/O device controller, and display electronics;
- initiate operation of the first and second devices in the low power mode based on the received selection;
- and
- place a first one of the multiple processor cores in a first operating mode and a second one of the multiple processor cores in a second operating mode based on the received selection, the first operating mode different than the second operating mode.
