That's my presentation about the same topic in Russian for KyivBSD 2010 conference. The mentioned guide in English can be found here: http://wiki.freebsd.org/TuningPowerConsumption I've just added there some points about AMD C1E state and its support in FreeBSD 8.x and 9.x from my knowledge. Unluckily I never had laptop with AMD CPU to really test power management there. -- Alexander Motin
