Type Cover Back Light Not Working

[anon(7901790)]

I just noticed this. Evidently, my type cover back light stopped work. The keyboard shortcuts F1 and F2 and Fn F1 and Fn F2 only lighten or darked the screen.

I disconnected and reconnected it. I've deleted and reinstalled the drivers, and I've run Windows Update. None of it worked.

What am I missing?

Update: I figured it out. It is the F7 key now.
