I'm pretty sure it's like any other computer. They don't actually *need* to sleep, but some would say that it saves energy overall if they do. I only put my Mac to sleep if I want to see the little light "breathe".SexyHolly said:Am I supposed to let my iMac go to sleep everytime I am away from it or can I just let a screensaver run? Thanks, Holly
Sleep mode uses almost no power anyway so it's about the same equivalent powerwise to shutting it off.warrenbert said:Hi schweb:
Why shouldn't Macs be shut down? I hear a lot of hype why Macs are better and all, but if I new that they required constant power I would have had second thoughts.
1) I can't find any advice from Apple recommending constant power-on or sleep.
2) I can't find any evidence that people who shut down regularly are having any higher incidences of problems than people who leave them on.
I've never had any problems from using the power switch, PC or Mac.
True, but that is why you have the option of putting the monitor to sleep after a specified amount of idle time. I believe that should turn off the backlight. Or you could lower the brightness to 0.technologist said:On computers with LCD screens, (iMacs, PowerBooks, iBooks, G5 towers with flat screens) the backlight in the display has a limited life. Putting these machines to sleep turns that backlight off, in addition to saving energy. Since you can't (easily) replace the display on an iMac or laptop when it dies, it's a good idea to prolong the life of that neon bulb as long as possible
Will "Mac-Janitor" do the same thing? I've heard, but not done a lot of research (though I hear it's as easy as pie to use...that's if you like pie, of course).schweb said:No, they won't run while the machine is asleep. I use Cocktail and run them every so often just to keep things running smoothly.
