HELP!! The keyboard on my Acer C7 has stopped working. i can press any key and I get nothing. I can plug in a wireless keyboard and it works fine. but my new problem is somehow the WiFi button was pushed to off, and now it acts like its locked. Nothing I do will fix it. I have gone to settings, clicked the WiFi button on the bottom of the screen, Used the wireless keyboard and nothing... Any ideas on how to fix this... The laptop is right at a year old...
