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.
