A method of performing a task in a computer system at a reduced power consumption state, said computer system comprising: (i) a service environment logic which comprises: a service operating system logic; and a service task logic to cause a processor to perform one or more service tasks, and (ii) an operating environment logic which comprises: an operating system logic; an application logic, and a service task management console logic to cause the processor to initiate and/or schedule a service task to be performed by the service environment logic; and (iii) a power management logic; said method including: virtualizing physical resources of the computer system by initiating virtual machine management logic on the computer system to host the operating environment logic and the service environment logic; characterized in that the method further comprises: exiting the operating environment logic and executing the service environment logic; switching a first set of at least one of the physical resources from an active state to a reduced power consumption state by means of the power management logic upon exiting the operating environment logic; maintaining a processor and a second set of at least one of the physical resources in an active state while executing the service environment logic; performing a service task under control of the service environment logic, including utilizing the processor and the second set of at least one physical resource while the first set of at least one physical resource is in the reduced power consumption state; and exiting the service environment logic upon completion of the service task. (i) a service environment logic which comprises: a service operating system logic; and a service task logic to cause a processor to perform one or more service tasks, and a service operating system logic; and a service task logic to cause a processor to perform one or more service tasks, and (ii) an operating environment logic which comprises: an operating system logic; an application logic, and a service task management console logic to cause the processor to initiate and/or schedule a service task to be performed by the service environment logic; and an operating system logic; an application logic, and a service task management console logic to cause the processor to initiate and/or schedule a service task to be performed by the service environment logic; and (iii) a power management logic; said method including: virtualizing physical resources of the computer system by initiating virtual machine management logic on the computer system to host the operating environment logic and the service environment logic; characterized in that the method further comprises: exiting the operating environment logic and executing the service environment logic; switching a first set of at least one of the physical resources from an active state to a reduced power consumption state by means of the power management logic upon exiting the operating environment logic; maintaining a processor and a second set of at least one of the physical resources in an active state while executing the service environment logic; performing a service task under control of the service environment logic, including utilizing the processor and the second set of at least one physical resource while the first set of at least one physical resource is in the reduced power consumption state; and exiting the service environment logic upon completion of the service task. virtualizing physical resources of the computer system by initiating virtual machine management logic on the computer system to host the operating environment logic and the service environment logic; characterized in that the method further comprises: exiting the operating environment logic and executing the service environment logic; switching a first set of at least one of the physical resources from an active state to a reduced power consumption state by means of the power management logic upon exiting the operating environment logic; maintaining a processor and a second set of at least one of the physical resources in an active state while executing the service environment logic; performing a service task under control of the service environment logic, including utilizing the processor and the second set of at least one physical resource while the first set of at least one physical resource is in the reduced power consumption state; and exiting the service environment logic upon completion of the service task. exiting the operating environment logic and executing the service environment logic; switching a first set of at least one of the physical resources from an active state to a reduced power consumption state by means of the power management logic upon exiting the operating environment logic; maintaining a processor and a second set of at least one of the physical resources in an active state while executing the service environment logic; performing a service task under control of the service environment logic, including utilizing the processor and the second set of at least one physical resource while the first set of at least one physical resource is in the reduced power consumption state; and exiting the service environment logic upon completion of the service task.
