I have a promethean activepanel 55. It randomly freezes and stops responding to touch.

when I unplug the usb from the laptop and plug it back in it starts working again. Also after restarting the laptop seems to fix the issue but only temporally. Any solution? 


  • Hello amit,

    Thanks for reaching out via our support community. We will need a little more information. Kindly advise of the version of ActivPanel you are using. This is typically located by the serial number https://support.prometheanworld.com/article/?kb=1088

    How are you connected to the ActivPanel?

    How long is the USB cable?

    Please test with another known working USB cable that is not longer than 9 ft.
