My keyboard on my Toshiba Satellite laptop isn't working. The power button is the only thing that works. I've tried Luna's suggestion but that does nothing once I'm done following the steps. It's crazy because when I power it on and press F2 repeatedly, the keyboard works fine in that screen. Can anyone help me? I have windows 8.1. Also, when I tried Luna's suggestion, my laptop made a funny noise (clicking), and I seen smoke coming from the side vents. Help!
