Yeah smano. I though so too.
Just unplug your keyboard,turn off the monitor,wait for 45 minutes for the monitor to cool down (those things can get hot you know),then finally interchange the ports you use for the mouse and keyboard. Power on and off in quick succession about 5 times. When you power on the 6th time,voila!
If that does not work,I suggest you go to SK offices (with your keyboard) and I am sure they will be able to sort it out.
