F8 keyboard light not working

[southpawrog]

Hi all:

When I press the F8 button, the level indicator comes up, but there's a "not allowed" symbol as well (the circle with the diagonal line through it). This is the same when I press the F9 and F10 buttons - it comes up, but also the "not allowed" symbol.

Can someone please help me? Thank you very much!

This is caused by attempting to manually override the automatic ambient light sensor. Normally, the lights kick in when needed. If you want to turn them on and off yourself, you'll need to disable the sensor. This can be done from System Preferences -> Keyboard and Mouse -> Keyboard tab.

I went there, and tried enabling and disabling the "illuminate in low light" and it still keeps the "not allowed" symbol. What am I doing wrong?

That can be the only issue, try turning it off then restarting and trying again.

problem solved!

Thanks for all you help. I figured it out...

For the sake of future generations, would you mind explaining how you ended up figuring it out?
