This problem was haunting me for the past two days and believe me it’s a real pain in the head. My Laptop Keyboard, which works without any problem stopped working all of a sudden. The keyboard was completely dead but the buttons like Wi-Fi, Bluetooth, Sound Increase/Decrease were working fine. I tried restarting, As this problem had occurred before and a successful restart can solve the problem. But this time, even after I restarted the PC, The keyboard wasn’t working and I surfed all over the web for an answer. If you are here, I believe you too must be having a similar problem.
This kind of hardware issues occurs due to variety of reasons like lack of driver, Damaged device, Dust, Power errors etc. In my case, Since the keyboard was working fine till the accident i was pretty sure that the problem was not with the Drivers. I tried cleaning the keyboard and checking it completely but couldn’t found any errors in it or anything worth noticing. So I tried all the way in the web and finally got a solution. Here I’ll explain the reasons why your keyboard must had stopped working and the solution to fix it from the ‘dead’ state .
