<title>Why is my laptop slow when it is on battery?</title>

Some laptops intentionally slow down when they are running on battery in

order to conserve power. The processor (CPU) in the laptop switches to a slower

speed, and processors use less power when running slower, so the battery should

last longer.

This feature is called CPU frequency scaling.
