Encapsulated smoke?! What the? I've never heard that one before. Could you please explain? I leave my system on 24/7 and have done so for years without any problems. (knock on wood!) From my research, that is the best way to go for some users. I'm on my computer every day and at all hours so it works for me. The only time I shut down is for upgrades, maintenance or if I'm going to be away for more than 12 hours. I used to shut down every day and THAT cost me a monitor! Yes, it was proven by the Mac techs that frequent on/off helped with the early demise of it. Weird huh? I'd never heard of that one either! brett (always learning something new!) Richard M.
