Abstract
An apparatus is described. The apparatus includes a computing system having a normal active mode and an active sleep mode. The active sleep mode consumes less power than the normal active mode. The computing system also has a high end system and a low end system. The low end system executes one or more tasks during the active sleep mode.
Claims27
A method, comprising:
- transitioning a computing system from a normal active mode controlled by a main CPU into an active sleep mode controlled by an active sleep mode CPU, wherein said main CPU activates said active sleep mode CPU and deactivates itself;
- transitioning said computing system from said active sleep mode to said normal active wherein said active sleep mode CPU activates said main CPU and deactivates itself;
- receiving information wirelessly through an active wireless I/O component of the computer system during said active sleep mode;
- and
- inactivating a graphics controller of the computing system during said active sleep mode.

A method, comprising:
- transitioning a computing system from a normal active mode controlled by a main CPU into an active sleep mode controlled by an active sleep mode CPU, wherein said main CPU activates said active sleep mode CPU and deactivates itself;
- transition ma said computing system from said active sleep mode to said normal active mode, wherein said active sleep mode CPU activates said main CPU and deactivates itself;
- reading information from a non volatile data storage device during said active sleep mode;
- and
- inactivating a graphics controller during said active sleep mode.
2 more elements
An apparatus, comprising:
- a computing system comprising a main CPU to operate said computing system in a normal active mode and an active sleep mode CPU to operate said computing system in an active sleep mode, said active sleep mode consuming less power than said normal active mode;
- said main CPU to execute tasks during said normal active mode, said active sleep mode CPU to execute one or more tasks during said active sleep mode;
- said main CPU coupled to said active sleep mode CPU:
- wherein said main CPU is to activate said active sleep mode CPU and to deactivate itself;
- wherein said activate sleep mode CPU is to activate said main CPU and to deactivate itself;
- and
- said main CPU coupled to a graphics controller, said active sleep mode CPU not coupled to said graphics controller.
