Наилучшие и наименее рискованные изменения, которые мы добавили в пакет pm-utils в Precise, чтобы помочь сэкономить энергию на аккумуляторах для ноутбуков.

Используя высокоточный мультиметр, было очевидно, что некоторые рекомендации «Хорошие» рекомендации по экономии мощности могут на самом деле не быть такими полезными, поэтому необходимо много проб и ошибок и точный способ оценки энергопотребления для обеспечения выбора оптимальная конфигурация для вашего оборудования.
