My numlock doesn't work properly from a long time ago. I just upgrade to Win 10 with a hope that is gonna be ok, but is working the same like on Win 7. The problem is that when the numlock is on the keyes that works are 1,2 and 9 and while numlock is on some of the letters from the main keyboard are working like 1 or 2. When the numlock is off, the main keyboard is working ok and the numpad is working like arrows. On linux there is no problem with the numlock, thats why I marked the problem like software. Thanks in advance if someone have solution for the problem.
