How to reverse fn function in lenovo g500h?

I tried to access BIOS but couldnt find the APP MENU to check the legacy mode. Any suggestions?

There's a BIOS update that was released recently that will let you do this on most lenovo laptops. You couldn't do this before this update. It was extremely frustrating, but it's all good now. Go to the lenovo website and search for the BIOS update for your specific model.
