My Keyboard dock has somehow just stopped charging... the tablet part charges fine when connected directly to the power, but when I connect the power to the dock it doesn't charge anything, neither the keyboard or the tablet, no lights come on at all. It still types fine and the trackpad works, it is just like the power supply to the dock is not working 
Does anyone know if this could be a hardware or software issue? I have updated to the latest drivers etc, I read on one site something about if the battery drains completely to flat and the bios... I'm not sure..
Its reallt upsetting though as this is only a few months old.
