Topics include how applications can interface with the Power Manager, how device drivers can intelligently manage device power state that is separate from the system power state, and how OEMs can modify the Power Manager component to provide custom power handling for their platforms.

Quoting from the introduction . . .

"In Microsoft Windows CE .NET, the Power Manager component was introduced to provide a framework for implementing sophisticated power management support. The Power Manager acts as a "mediator" between the kernel/ OEM Adaptation Layer (OAL) and device drivers and applications, and coexists with drivers and applications that are not power managed. Within this framework, device power state can be managed separately from the system state, so devices that are capable of intelligently managing their own power are now able to do so. With the release of Windows CE .NET 4.1, Microsoft introduced support for a number of new features for power management. You can take advantage of greater power savings capabilities by updating your platforms and device drivers to use these new features, which include . . ."

And from the conclusion . . .

"The new features in Windows CE .NET enable you to extend power savings and battery life for embedded systems and devices. With Windows CE .NET 4.1 applications can now interface with the Power Manager, and device drivers can intelligently manage device power state that is separate from the system power state. As this article has demonstrated, OEMs can modify the Power Manager component to provide custom power handling for their platforms . . ."
