Function Button

[Oyuna]

Hello Everyone,

I own Asus Ultrabook, and the fn (function button) isn't working. I know it's not damaged because I didn't spill or I did nothing to harm the button. I know last night my cat was walking on my keyboards and I think he did something to deactivate the fn button. lol
Please let me know how to fix it.

Cheers,
Thanks

The first thing I would do is a simple reboot and see if things are normal.
What operating system did your ultrabook come with?
