Latest reply from service center:
Good morning, the charge port issue needs to be investigated further. We will create a follow up. Currently we do not have solution and will follow up once we determine the root cause. We were able to get the button to work after updating the software. Now we understand the issue still remains. Our virtual team will start the review process. Thank you.
