Why does my screen go dim after a while?
When your laptop computer is running on battery, the screen will dim when the computer is idle in order to save power. When you start using the computer again, the screen will brighten.
You can stop the screen from dimming itself:
Click the icon at the very right of the top panel and select System Settings.
Open Screen and uncheck Dim screen to save power.
