I've already do everything (almost) http://wiki.freebsd.org/TuningPowerConsumption but still a very basic problem. When I boot my laptop under FreeBSD and I do nothing the fan don't run. But if I do anything (launch firefox, launch a find etc...) instantly the fan run (instantly= 1 or 2 sec). Event when I just boot and the back of the laptop is very cold. I can use my ear to known if I got a flashplugin in the web page...without sound.....the fan warn me:-( But when I boot Windows 7 I can launch many thing simultaneous the fan never run or after long moment and when the back of the laptop is hot. Any idea ? Regards. NB: The Laptop is a Dell latitute E6220 and it's run FreeBSD 9/stable -- Albert SHIH DIO bâtiment 15 Observatoire de Paris 5 Place Jules Janssen 92195 Meudon Cedex Téléphone : 01 45 07 76 26/06 86 69 95 71 xmpp: jas@obspm.fr Heure local/Local time: jeu 15 nov 2012 00:34:09 CET
