Celle-ci permet au BIOS de gérer l'alimentation du système, réduire la cadence du CPU, désactiver certains périphériques après une période d'inactivité (lecteurs de disques-dur, CD-ROM...). L'APM permet ainsi une économie d'énergie.
Aujourd'hui la norme utilisée pour la gestion de l'énergie est l'ACPI, qui a remplacé l'APM.
Linux
Dans le paramétrage du noyau Linux (avant sa génération), une liste de paramètres pour la gestion de l'énergie ACPI et APM est proposée.
Si l'APM (paramètre CONFIG_APM) est configuré (cas d'un ordinateur relativement ancien), alors il y a sept paramètres à configurer :
