Hi.. Suddenly my docking station has stop supplying power to my keypad.. when removed and connected directly to the book, power is resumed and all is okay but for some reason it will not power up the keypad or book when connected directly. All other functions on the docking station appears to work fine.. I am guessing the issue is with the keypad and not the actually docking station. If this sounds familiar, would be appreciated to hear from you.. thanks.
