    How often should i put my iMac to sleep?
    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

    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".

    I like the sleep feature on Macs. It actually works; I could never get it to work quite right on my MS machines. It always took too long to get things going. With my Mac, I just hit the power button and when I get back, I just press the "any key" and everything is good to go.

    So far, 100% wake-up rate after 2 years

    Good rule of thumb is if your gona be away for an hour or better put it to sleep. Anything under that let the screen saver take over. I would say if your going to be away more than 6 hours just shut it off. Doesn't take that long to boot back up and you will save some on electric bill.

    I usually put mine to sleep at night and when I'm at work. I do it more for the whole saving energy/environmentally friendly thing. Many people leave their Macs on all the time without a problem.

    So really it's more of a personal preference.

    But never shut it off unless you have to for some reason. Macs are designed to not be shut off, rather they should just be put to sleep.

    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.

    i don't think it matters anymore w/ modern computer systems (Mac and PC). i turn my mac mini off if i'm not going to use it for 1 hr or more at home. when i bring it to work, i usually leave it on from mon to fri and just turn off my LCD when i leave work.

    Sleep mode uses almost no power anyway so it's about the same equivalent powerwise to shutting it off.

    Sleep of course is advantageous in that you don't have to wait for the machine to boot back up and load everything again.

    There should be little harm in shutting off the system, however there is little advantage to it either. One thing to keep in mind if you do shut down or sleep your system is that you might need to do the scheduled maintenance manually as needed.

    If you do leave it up all the time with a screensaver I would not use a processor intensive one though.

    Can the computer run it's automated tasks (the ones @ like 2am) while the thing is asleep? I've never actually thought about it much.

    Yes, I have heard that there are some legacy Unix-derived tasks that are set to run at night. Do they do any good? Will they run during "sleep"? Is it better to just run Onyx or something?

    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.

    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

    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.
