Activity Timer Time-outs and the Power Control Panel Utility (Windows CE 5.0)
The activity timer time-outs indicate how long the Power Manager should wait prior to deciding that a particular activity source is inactive. This causes an inactivity event to be signaled. The control panel utility determines how long the inactivity event must remain signaled before the Power Manager will initiate a system power state transition.
Activity timer time-outs should be smaller than the system power state time-outs but larger than the expected activity interval. For example, the system state time-out might be measured in minutes and the user activity timer might be 10 seconds. This prevents frequent activity timer state transitions during normal operation, but the user may be inactive for 10 seconds before the OS notices.
The timeouts listed in the Power Control Panel utility program are cumulative. That is, if each timeout is set to 1 minute, it will take the system 3 minutes to suspend as it passes through each intermediate system power state.
