Пакет: powermgmt-base (1.33)

common utils for power management

This package contains utilities for power management; beside certain mostly obsolete scripts, you'd want this package for "on_ac_power" which lets you determine whether the system is powered from battery or an abundant supply. It's recommended to use this tool over a simple sysfs check, ConditionACPower or other ad-hoc methods which notoriously fail to account for unobvious quirks, both old and new.
