# Mengapa laptop saya lambat ketika memakai baterai?

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.
