Remarks

Windows sets the value of DEVPKEY_Device_PowerData. The value of DEVPKEY_Device_PowerData contains a CM_POWER_DATA structure.

You can call CM_Get_DevNode_Property or SetupDiGetDeviceProperty to retrieve the value of DEVPKEY_Device_PowerData.

Windows Server 2003, Windows XP, and Windows 2000 support this property, but do not support the DEVPKEY_Device_PowerData property key. Instead, you can use the corresponding SPDRP_DEVICE_POWER_DATA identifier to access the value of the property on these earlier versions of Windows. For information about how to access this property value on these earlier versions of Windows, see Accessing Device Instance SPDRP_Xxx Properties.
