  <title>Enable automatic brightness</title>

  <p>If your computer has an integrated light sensor, it can be used to
  automatically control screen brightness. This ensures that the screen is
  always easy to see in different ambient light conditions, and helps to reduce
  battery consumption.</p>

      <p>Open the <gui xref="shell-introduction#activities">Activities</gui>
      overview and start typing <gui>Power</gui>.</p>

    <item>
      <p>Click <gui>Power</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the <gui>Power Saving Options</gui> section, ensure that the
      <gui>Automatic Screen Brightness</gui> switch is set to on.</p>
