f2 and f3 brightness keys not working

My function keys for brightness aren't working. Is there anything that i can do to fix that? Also what could have caused it?

Re: f2 and f3 brightness keys not working

Have you tried holding the Fn key down and then use the F2 F3 keys?

Did you install any software lately? Did the function stop working after that?

Re: f2 and f3 brightness keys not working

The only software i remember downloading recently is adobe flash player. Do you think that might have triggered it?

I don't think so, have you restarted the PC?

Re: f2 and f3 brightness keys not working

I have the same problem, the brightness keys (f2 and F3) are not working, with FN pressed. This issue is since around 2 months, have restarted the Unit many times....

Can you help?
