Laptop?

Your laptop probably has an ambient light sensor, and the screen brightness  
gets autoadjusted based on its reading; either that, or Fedora is restoring  
the saved display brightness setting.

Your keyboard must have an ACPI keystroke combination that adjusts screen  
brightness, and/or ambient light sensor on/off.
