<title>Use less power and improve battery life</title>

<p>Computers can use a lot of power. By using some simple energy-saving
strategies, you can reduce your energy bill and help the environment.</p>

<title>Allmänna tips</title>
<list>
  <item>
    <p><link xref="shell-exit#suspend">Suspend your computer</link> when you
    are not using it. This significantly reduces the amount of power it uses,
    and it can be woken up very quickly.</p>
  </item>
  <item>
    <p><link xref="power-off">Turn off</link> the computer when you will not be
    using it for longer periods. Some people worry that turning off a computer
    regularly may cause it to wear out faster, but this is not the case.</p>
  </item>
  <item>
    <p>Use the <gui>Power</gui> preferences in <app>System Settings</app> to
    change your power settings. There are a number of options that will help to
    save power: you can <link xref="display-dimscreen">automatically dim</link>
    the display after a certain time; <link xref="display-dimscreen">reduce the
    display brightness</link> (for laptops); and have the computer <link xref="power-suspend">automatically suspend</link> if you have not used it
    for a certain period of time.</p>
  </item>
  <item>
    <p>Turn off any external devices (like printers and scanners) when you are
    not using them.</p>

     <p><link xref="display-dimscreen">Reduce the screen brightness</link>;
     powering the screen accounts for a significant fraction of a laptop power
     consumption.</p>
     <p>Most laptops have buttons on the keyboard (or a keyboard shortcut) that
     you can use to reduce the brightness.</p>
   </item>
   <item>
     <p>If you do not need an Internet connection for a little while, turn off
     the wireless/Bluetooth card. These devices work by broadcasting radio
     waves, which takes quite a bit of power.</p>
     <p>Some computers have a physical switch that can be used to turn it off,
     whereas others have a keyboard shortcut that you can use instead. You can
     turn it on again when you need it.</p>

     <p>Reduce the number of tasks that are running in the background.
     Computers use more power when they have more work to do.</p>
     <p>Most of your running applications do very little when you are not
     actively using them. However, applications that frequently grab data from
     the internet, play music or movies can impact your power consumption.</p>
