1. Inspect the Buttons: Check whether any buttons are stuck or unresponsive. Gently press both sides to compare the tactile feedback—if one side feels different or doesn’t respond properly, the button may be damaged.
  2. Power and Restart: If the buttons appear to be functioning normally, connect the stand to a charger and allow it to charge briefly. Then, try restarting the device.
  3. Left Button Functionality: Please note that the left button supports different functions based on press duration:
  • Press and hold for 2–3 seconds to turn the device on
  • Press and hold for 4–5 seconds to turn it off
