Thanks for posting on the Support Community.
With regard to the ActivBoard, could you provide the model number? (Please do not provide the serial number).
In most instances where connection issues occur this relates to either the ActivDriver or USB cable.
I would recommend downloading the latest ActivDriver (5.11.7) from article 10902 on http://www.Prometheankb.com.
Please remove the current USB cable between the computer and the ActivBoard prior to installation. Once the installation has finished, please restart and then connect the USB cable.
Should you still have no connection to your ActivBoard, please advise us if the LED in the top left corner is on? If so, what colour?
If the colour of the flame is red, I would recommend testing another known working USB cable from another ActivBoard if possible and if still no connection test directly into the ActivBoard bypassing any extenders or wall plates in use.
Should you wish to get in touch with Promethean Technical Support directly please quote your reference number which is 00566364
