Get System Power Management Capabilities
The following steps describe how to retrieve all the possible power states of a platform and all the power state changes that Intel AMT can activate. This use case uses the Power State Management Profile definitions ofCIM_PowerManagementCapabilities.
1. Retrieve the instance of CIM_PowerManagementCapabilities, using the “InstanceID” key equal to “Intel(r) AMT:PowerManagementCapabilities 0”.
2. Examine CIM_PowerManagementCapabilities.PowerChangeCapabilities.

$powerChangeCapabilities =$powerManagementCapabilitiesInstance.GetProperty("PowerChangeCapabilities")
