INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract One or more techniques and/or systems are provided for assigning power management classifications to a process, transitioning a computing environment into a connected standby state based upon power management classifications assigned to processes, and transitioning the computing environment from the connected standby state to an execution state. That is, power management classifications, such as exempt, throttle, and/or suspend, may be assigned to processes based upon various factors, such as whether a process provides desired functionality and/or whether the process provides functionality relied upon for basic operation of the computing environment. In this way, the computing environment may be transitioned into a low power connected standby state that may continue executing desired functionality, while reducing power consumption by suspending and/or throttling other functionality. Because some functionality may still execute, the computing environment may transition into the execution state in a responsive manner to quickly provide a user with up-to-date information. ## Claims ### Claim 1 A method for transitioning from a connected standby state to an execution state, comprising: detecting an exit connected standby request associated with a computing environment; and transitioning the computing environment from a connected standby state to an execution state, comprising: restoring execution functionality to a suspended process assigned a suspend classification; restoring execution functionality to a throttled process assigned a throttling classification, the restoring execution functionality to a throttled process performed before the restoring execution functionality to a suspended process; and continuing execution functionality for a hardware functionality process assigned an exempt classification, the hardware functionality process allowed to execute during the connected standby state. ### Claim 2 (depends on 1) The method of claim 1, the computing environment comprising an operating system. ### Claim 3 (depends on 2) The method of claim 2, the operating system comprising at least one of a tablet operating system, a desktop operating system or a mobile device operating system. ### Claim 4 (depends on 1) The method of claim 1, comprising: restoring execution functionality to a parent suspended process before restoring execution functionality to a child suspended process. ### Claim 5 (depends on 4) The method of claim 4, the child suspended process configured to consume a second resource from the parent suspended process. ### Claim 6 (depends on 1) The method of claim 1, the restoring execution functionality to the throttled process comprising: restoring execution functionality to the throttled process based upon a throttling schedule applied to the throttled process. ### Claim 7 (depends on 1) The method of claim 1, the restoring execution functionality to the throttled process comprising: unapplying a throttling schedule applied to the throttled process. ### Claim 8 (depends on 1) The method of claim 1, the restoring execution functionality to the throttled process comprising: if the throttled process is in a non-executing suspended state, then transitioning the throttled process into an executing state. ### Claim 9 (depends on 1) The method of claim 1, the suspend classification corresponding to: whether a process is able to be suspended without a computing system failure and limited runtime functionality associated with the process is not desired. ### Claim 10 (depends on 1) The method of claim 1, the throttling classification corresponding to: whether a process can be throttled without a computing system failure and limited runtime functionality associated with the process is desired. ### Claim 11 (depends on 1) The method of claim 1, the throttled process comprising a service created within a system session that provides desired state functionality. ### Claim 12 (depends on 1) The method of claim 1, the suspended process comprising a user application created within a user session. ### Claim 13 A system for transitioning from a connected standby state to an execution state, comprising: a transition component configured to: detect an exit connected standby request associated with a computing environment; and transition the computing environment from a connected standby state to an execution state, comprising: restore execution functionality to a suspended process assigned a suspend classification; restore execution functionality to a throttled process assigned a throttling classification, the restoring execution functionality to a throttled process performed before the restoring execution functionality to a suspended process, the suspended process configured to consume a resource from the throttled process;

and transitioning the computing environment from a connected standby state to an execution state, comprising: restoring execution functionality to a suspended process assigned a suspend classification; restoring execution functionality to a throttled process assigned a throttling classification, the restoring execution functionality to a throttled process performed before the restoring execution functionality to a suspended process, the suspended process configured to consume a resource from the throttled process;
