My computer went through an update and after it was done, I turned it on and for some reason, some of my function keys stopped working. For example: the only function keys that work are the, turn up and down brightness and sleep mode. Before, I could raise and lower my volume through the keyboard, turn on my keyboards back light and turn on my laptops' WiFi, but now I cant. My last resort is to restart my whole computer all over again, but I really don't want to do that... Please Help!
