Thank you for reaching out to Autonomous! I am sorry to hear that you are having some trouble with your SmartDesk but I will be glad to assist. It sounds like your system needs a "hard reset" can I please have you follow these steps thoroughly.

Reset Steps:
Unplug the desk for 20 seconds. Plug it back in. Wait a full 20 seconds.
