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.

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.
