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.

Note:
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.
