what does Mac sleep do?

hi! what does mac sleep do? is it the same as standby? will it;

-turn off the HDD
-turn off the fan
-turn off everything else except the RAM

 

It does what you want it to do.

It will turn off HDD if you tell it too, it turns off your wifi as well if you decide you want your HDD off (kinda weird), the fan isn't really turned off it will turn on if it needs too, but I cant see why it would do it. it's just turning off the display and clocking everything down to a minimum to keep the machine operational.

 

ahhh, ic, because in windows, u put the computer on standby because u want to move it, hence turning off the HDD, to prevent damage. ooops, why did i say fan, off course it will turn on, lol, unless i want a fried notebook! so if u want to move ur mac u have to "turn it off" then?

 

this is new to me, i never knew it was standard to turn off the hd when moving ur laptop, usually i just either close the lid if im taking it a far distance, or if only a couple feet i move it

 

Well, in both Windows and OS X you have the option if the HDD is turned off when in sleep mode, however for Mac notebooks its not really required, because all Mac notebooks come with Apples sudden motion sensor technology, this technology automatically locks up the HDD from doing anything when movement is detected.

Don't believe such a technology exists? Check out MacSaber, it's a program that mimics the Star Wars LightSaber sounds by using the Sudden Motion sensors for movement, depending on the movement is how loud the sound will be, and such.

So really, you don't have to have it off, it's up to you. Personally I leave the HDD on because the machine wakes up much faster, as well as the Wifi is still retained and I don't need to wait for it to connect.

Anyways, this shows you how much thought Apple puts into designing their products not only in the sense of style, but definitely for usability. One of my other favorite features of MacBook (I'm not sure if MBP has this, could someone confirm this by the way?) is the small pinhole size LEDs on the battery that tell you how much power is in the battery without the need for turning on the machine. Far as I know, Apple notebooks are the only one that has such a thing, same goes for the sudden motion detector.

Apple truely is the 'Luxary' notebook out there.

 

hmm, by default it should be the exact same as standby, only the ram is on to maintain its state. I didn't know it could be edited.

 

well, it is a good idea to turn off ur hard drive it the laptop ur carrying will be juggled enough to trigger the sudden motion thing. yes it is possible to have the hard drive on while ur carrying it without causing damage; but it just is not a good idea, and i wouldn't take the risk. hasholly, make sure u turn off the computer computer if u put ur computer in a bag, coz its not good for the hard drive, and besides the lappy will overheat for sure, remember the fan could be triggered while it sleeps.

btw, hate to burst the bubble but; that apple battery ur talking about is invented and produced by sony, it is also used in dell laptop, it is of very similar variant (if not same). sudden motion sensor (first introduced mid 2005) is first used in IBM thinkpad line; called Active Protection System (first intoduce in 2003).

while i'm at it, the ipod wheel is a copy of B&O BeoCom 6000, incl. the digital clicky sound. it was first produced in 1998, the ipod is designed in 2001.

well, don't feel bad there's the first time for everything ...

 

Apple does not use Sony batteries anymore in their current notebook line from what I know, if they did they would be part of the battery recall, which they were not, I have owned a Sony vaio before, and have not seen the feature on it that I'm talking about, nor do I see it in any current pictures of current models, you have a picture of this? The Apple battery has 5 pinholes on the battery itself that when a button (also on the battery itself) is press it actives these lights which tell you how much power is in the battery. I personally haven't seen this on neither Sony or Dell notebooks that I have owned or own right now.

The IBM 'Active Protection System' is an analogous system to apples own Sudden Motion Detector, meaning in some fashion its the same, but not entirely, so I wouldn't go as far as saying they are the same. The only real similarity they have is they both use sensitive accelerometers and their objective is to protect the HDD, however their uses are implemented differently. IBM's Active Protection System does not work when the system is in sleep or hibernation, where as the Apple Sudden Motion Detector does. There is no way to deactivate the SMD in Apple notebooks unless you go into termal and type out a command, where as in IBM notebooks its readabily and easily accessable. There are a few other differences between the two.

In 2004 Apple hired a different company to design the new click wheel thats still in use today, just because the first one they were using wasn't cutting it for them, regardless of if this company you're talking about made it first, Apple now owns rights to use it.

Anyways, everything you said is not the same (still waiting on the sony battery one reply). As for the other things there are similar systems out there, however not similar enough that I would say they are the same.

I wouldn't go that far saying that I didn't know this stuff. Most users here are not that technical with computers, they only understand it to a certain degree, and use the site as an easy to understand reference to help them purchase a notebook, so I avoid from talking in a way that will scare them away.

One last thing, you don't need to 'juggle' Apple notebooks that hard to activate it, otherwise the iAlert software is totally useless.

 

i think you need to explain how you know/think sleep does this. Unless you are thinking of some kind of different sleep mode.

When you close the lid or choose sleep from the apple menu or press the power button and choose sleep, it will be the exact same as standby. Everything is off except ram.

I find this thread could be very confusing to less knowlegdable users and needs more clarification of what has been said.

 

Exactly why in my last post that I avoid getting technical about anything here, not everyone here is in Computer Science or IT field.

I should clarify myself better, in OS X you can have the option of if your HDD is turned off when you go into sleep mode, or you can leave it enabled. In Power options there is a option called "Turn off HardDrive if possible" personally I don't have that option turned on, for different people some have it on or off. From the standpoint of if your HDD is safe from movement, shouldn't be much of a concern because of the Sudden Motion Sensor, if there is constant movement, it keeps the drive locked.

 

ah, i thought you were thinking about that option. That option would be the same as the "shut off hard disk when idle" option in windows. it doesn't affect the sleep mode itself.

when you put it to sleep, that option has nothing to do with it.
