<title>Why is my laptop slow when it's on battery?</title>
<p>Some laptops intentionally slow down when they are running on battery in
order to conserve power. The laptop's processor (CPU) switches to a slower
speed, and processors use less power when running slower, so the battery should
last longer.</p>
<p>This feature is called <em>CPU frequency scaling</em>.</p>
