non responsive Smartboard
we have a smart board that doesnt seem to respond to touch. when it is attached to a laptop it seems to respond, the light turns green and the PC acknowledges that a board is connected. The board even reacts to a pen being picked up but if you touch the boards surface theirs no movement or reaction.
I've tried the reset switch on the back right hand side and i've also tried disconnecting and reconnecting the pen tray lead in both of the sockets.
Is this board dead or is their another trick i can try.
