Power Management

A version of this page is also available for

Windows Embedded CE 6.0 R3


The Power Manager control panel manages device power, improves overall OS power efficiency, and coexists with applications and drivers that do not support Power Manager.


In this discussion, device refers to a peripheral device with a device driver. It does not refer to an entire system such as a target mobile device.

You can use power management to reduce the power consumption of a device and maintain and preserve the state of the file system in RAM in the Reset, On, Idle, and Suspend power states.

Power Manager also provides the following capabilities:

  • A framework in which devices can intelligently manage their own power.
  • A mechanism for decoupling the power state of a device from the Suspend or the Resume state of the system.
  • A module that has a global view of the system environment, power status, and device power states. You can customize the Power Manager to make system-wide decisions about power that are suitable for your device.
