* The API provides the P&S power state keys that are updated by the HW Resource 

* Manager Server. These keys provide up-to-date information on the charging 

* status, battery level and battery state of the device. Any application may 

* subscribe to these P&S keys that are updated to receive notifications of 

* any change in state.

* This interface relies on the Publish and Subscribe (P&S) interface provided

* by Symbian. P&S is used by HW Resource Manager to globally publish the power

* state information.

* The P&D UID is #KPSUidHWRMPowerState and following keys are provided:

* - #KHWRMBatteryLevel

* - #KHWRMBatteryStatus

* - #KHWRMChargingStatus
