On my dell latitude e5470 pressing fn+f12 or f11 will turn the screen black. I have to force shut down the laptop then boot it back up it shows another black screen, shut it down again and then it works. The Fn key puts the laptop to sleep.

[OS = Windows 7]

Are you playing any games or using any apps that are or could be re-configuring Function keys?


As for Windows 7:

Start working with the function keys one by one to determine what each one is actually doing and what toggles are occurring.

No I am not playing any games or have installed any apps that have re-configured then function keys. FN + any f key turns the screen black. I have to force shut down the laptop then boot it back up it shows another black screen, shut it down again and then it works.
