Device Power Management Guidelines

Windows CE .NET

The Power Manager does not impose strict restrictions on device power consumption or responsiveness, or capabilities in any of the states. However, devices in states D0 and D1 should be functional from the perspective of the user, and higher-numbered states should generally consume less power than lower numbered states.

These simple guidelines make it easier for OEMs to write meaningful system power states without having to know details of the power levels of individual devices.
