My tablet keyboard was working for one day and then suddenly stopped working the next. Its one that can attach and detach from the tablet. I checked and made sure it was not any language option that was wrong, and also tried pressing the function key and the caps lock key together, but it didn't work. Whenever I try to type u, it comes out with -u. Whenever i press o, it comes out with =o. The bottom of the keyboard is fine, its just really the top. Also when I try to hit backspace, my keyboard just prints this ( and repeats itself. Please tell me if you know anything about this problem.
