<title>Ralentissement de l’ordinateur portable fonctionnant sur batterie</title>

<p>Quelques ordinateurs portables sont intentionnellement prévus pour ralentir dès qu’ils passent sur batterie afin d’économiser l’énergie. Leur processeur (CPU) se commute sur un cadencement inférieur pour consommer moins d’énergie et faire durer la batterie plus longtemps.</p>

<p>Cette fonction est appelée <em>gestion de la fréquence d’horloge du processeur</em>.</p>
