<p>Turn off 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 modern computers are quite robust, so this shouldn't be an issue.</p>

<p>Use the Power Management preferences 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 or send it to sleep after a certain time; <link xref="power-brighter">reduce the display's brightness</link> (for laptops); and have the computer <link xref="power-suspendhibernate">automatically go to sleep</link> if you haven't used it for a certain period of time.</p>

<p>Most laptops have buttons on the keyboard (or a keyboard shortcut) that you can use to reduce the brightness.</p>

<title>More advanced tips</title>
72
<p>Reduce the number of tasks that are running in the background. Computers use more power when they have more work to do.</p>
73
<p>Most of your running applications do very little when you're not actively using them. However, applications that frequently grab data from the internet, play music or movies, or run distributed calculations can impact your power consumption.</p>
95
<p>Vähennä taustalla pyörivien tehtävien määrää. Tietokoneet käyttävät sitä enemmän virtaa, mitä enemmän tehtäviä niillä on hoidettavana.</p>
