I'm not sure the model of my Asus laptop, other than that I got it in 2012. I was annoyed with accidentally moving my finger around on the mouse and swiping the screen from one thing to another unintentionally. I had seen that you could use fn+f9 to turn off that but didn't know it would turn off the pad completely. Now I'm unable to turn it back on. It doesn't even show up in my device manager as an option. Is there some way I can fix this issue?
