So science says "can you repeat this phenomena?" I shut down the fridge, put the Mac to sleep, turned the fridge back on… and yes the wake-up call for my Mac. I will try another power outlet for the fridge, or by a new one :-) Greetz, Pete Hi Gary,

Since the OS is just another program, it can become corrupted in RAM. Restarting or Shutting Down gives the OS a chance to be loaded into RAM fresh and gives the computer a new lease on life.

There is a preference for that. But it could also be a USB device or a bluetooth keyboard. You'll need to experiment. Could be network access. There is a preference for that.

I stopt using it though, because both mij iMac and MacBook woke up in the middle of the night to many times. The iMac lit up the sleepingroom, so I woke up too... I did not find a solution for this. Thought it maybe was waking up because of the router, but I am not sure. Any sugestions Gary (or anyone)? Thanks for your show, I like it very much! Hi Gary,

I have Parallels and I often leave that running as my Mac goes to sleep. But I'd ask VMware and do what they recommend. Haven't seen the screen problem, sorry. Any other reports of it at the discussions.apple.com forum? I’m not sure. I have Parallels and I often leave that running as my Mac goes to sleep. But I’d ask VMware and do what they recommend.

Is that not necessary as well? I dont think you mentioned that MBP's store a hibernation image when you put them to sleep. This is a wonderful thing to know and seems to be another great thing about sleep mode. Lastly, when I don't enter my password quickly enough after awake from sleep, I sometimes have trouble getting the screen to turn on. Have you seen that problem? Any advise?

And I'll tell you why. First of all, what you have to know .... is that on booting up process ... the computer consumes all most the same power like where it is in the IDLE-ON stage (something between 70-85 W). When a Mac is in a sleep mode - SLEEP-WOL off (Wake On LAN) consumes no more than 2 W ... yeah ..... you read it right, 2 W. And now ... for example .... you're sleeping 10 hr/night ... 10 x 2 = 20 W ... when you're turning ON your computer it gets 60-80 W .... how come you can tell about that the SLEEP mode is takes almost 1KW ? if you don't know some technical facts .... and because, maybe, you don't want to know them ... is much better, I think ..... to search before writing something like that.

There is no hard data to back it up. You are welcome to perform experiments with equipment yourself if you like. I considered it, of course, but the time and budget would be way too much. It is not debatable, though, that a Mac shutting down and a Mac booting up take up energy and that during that time the computer is not in use by its owner. It is also not debatable that a sleeping Mac uses some energy. So it is a matter of where the break-even point is. My background in computer software and hardware and in science suggest that as long as someone is using their computer frequently, as they would if it is part of their job and/or life, that sleeping is the better option.

You say that putting your Mac to sleep uses less energy than shutting down and rebooting, but you give no figures, no data to support your assertion. Your opinion boils down to just that, your opinion, and unless you can back it up with figures, amounts to no more than anecdotal evidence. This in itself isn't problematic, until you consider the fact that your podcast has the potential to directly affect the behavior of millions of Mac users. A sleeping Mac may use no more that a kilowatt more than a rebooted Mac; not much when you calculate your monthly electric bill, but multiply that kilowatt by millions, and suddenly we're in need of several new coal-fired power plants. My guess is that most Mac users can multi-task, and can do more than one thing while their computers are rebooting. The image of a Mac user staring at her rebooting screen while precious seconds are ticking away is laughable. The image of millions of Mac users burning up resources unnecessarily may be just as laughable... or is it? I enjoy your podcasts, and have actually learned a few things from them. I'd love to see you revisit this issue, after you've done your research. Your sleep vs shutdown comparisons leave me unconvinced.

I like it for many reasons, one of which is the quick wake-up time. This way, I can get up in the morning and quickly check the weather or my e-mails before heading off to class. This also allows me to open everything I will need for an assignment or to study for a test, and it is always where I want it when I am ready to do homework or study. I shut it down every night when I first got it, but because of the reasons listed above, I quickly realized that sleep mode was the way to go.

I got my first mac in 1999 and have always used sleep but once or twice I'll use the deep sleep widget (same as pulling out laptop battery once asleep) to preserve battery charge if sleeping for a day or two. I gave my old Macbook Pro to my father last year and when I got it back recently I had a peek at the uptime which was showing 134 days! http://blog.scoopz.com/2008/10/17/macbook-pro-uptime-of-134-days/ I've still got a windows (Dell Inspiron) laptop and my workstations at the office are windows but I tell all my staff to shutdown rather than sleep, too many clitches with windows (xp) sleep imho.
