This page has information about Power Management for Linux. Power Management exists because many products are handheld or mobile, and consumers are interested in using their products for as long as possible on a single battery charge.

Power Management Technology/Project pages

  • http://www.lesswatts.org/index.php - LessWatts.org
    • LessWatts.org is about how you can save real watts, however you use Linux on your computer or computers.
    • LessWatts is about creating a community around saving power on Linux, bringing developers, users, and sysadmins together to share software, optimizations, and tips and tricks.
