Troubleshooting the Test
* The platform must have power managment capabilities.
* The platform must support the standard power states used in this test which target the DEFAULT and PDA versions of the Power Manager.
* Ensure that the device is able to resume properly from the suspended state. If the resume does not happen correctly, it may affect the functionality of the device and test results.
