IiMac sleep setting

I am new to Time Machine and have just connected a G Tech external drive, which seems to be an excellent product. I have my energy saving settings for one hour and then the iMac goes to sleep, but then Time Machine will not backup again until the Mac wakes up. On the initial every hour for 24 hours there were no backups from 10:00 pm till 08:30 the following morning. Will Time Machine not function if energy saver settings are applied - Is this normal - does it mean that I cannot use the energy saver settings with Time Machine? Thanks in advance

all computer operations are stopped when mac goes to sleep. no processes at all including time machine can run while your mac is asleep. the backups will resume normally once the mac awakes. there are no problems with the settings you are using.

Can I access system preferences, WHILE migration assistant is running on the source computer, to change the sleep setting?

I have started Migration Assistant and have NOW learned that I was supposed to change the sleep setting in System Preferences to 'never'. Since M.A. is running right now, can I change the setting or will it mess up the transferring of data??

Thank you for responding. We did continually move the cursor for a few hours, but still had 13 hours to go, so after feeling we had nothing to loose, we did go into System Preferences to turn off sleep mode and we were able to do so on the source computer. Now in the morning we see that MA kept running for 8 additional hours.

IMac late 2013 does not have "Computer sleep" setting in Energy Saver prefs

I seem to be missing the "Computer sleep" setting in my Energy Saver pref window. All I see is "Turn display off after" setting. The computer does go to sleep.Is this a change that was made for recent iMacs?

It appears that the chip manages the power states itself. Again getting exact information on this is a pain and I'm really surprised (well maybe not so surprised) that Apple hasn't said anything about this. You'd think if they make such a drastic change to the system and to the Energy Savings pane of System Preferences there would be something.
From http://www.itpro.co.uk/desktop-hardware/19655/intel-haswell-release-date-and-spe cs-revealed#ixzz2iJsWa73p
Haswell chips will have 3 power states, compared to two in its predecessor, Ivy Bridge. These will be Active, Sleep, and Active Idle. Intel claims the advanced power saving will help give it at least 20x power consumption improvement over third generation chips.
It appears that the CPU will put itself to sleep if it is inactive for so many cycles. In a way this makes sense, the old method of telling the system to sleep after so many minutes is really very imprecise.
The only reason not to put the system to sleep as soon as it is idle is that it takes some amount of time to wake-up. So the lag would be annoying if it happened each time the system was idle. With the Haswell chip (as near as I can make out) wake-up is almost instantaneous. So there is no lag going from sleep to running. With no lag then it becomes feasible to put the CPU to sleep sooner and more often.
Again there is nothing I can point you to that states this it's what I've pieced together from various sources. In any case the missing setting in System Preferences is not an error so I guess you'll get to experience fist hand how this all works. Post back with your observations, it will be interesting to hear what you think.

Sleep setting has suddenly gone missing on 20GB 4'th Gen. refit

When my 20GB, Gen 4, Ipod died, I had the extended warrenty. True to their word, when Apple couldn't fix it, they replaced it. I think the new one they sent me is a refit, but it has worked fine until now. For whatever reason the "sleep" setting has gone missing from all my menus! Very Strange. I thought perhaps the latest update had something to do with it, but my 5'th Gen. 40GB, video Ipod, was also updated... and it still has a sleep setting.
I have been putting the 20GB to "sleep" by holding down the clickwheels lowest point, the screen goes dark... but when I restart it, it's been playing, because the battery is always dead.
Am I missing something here? I know it seems strange... so that's why I've come back to discussions. Anybody?

Sleep setting questions

I'm running 10.5.2 on a new MacBook Pro. Is the sleep setting a "safe" sleep (does it save to RAM)? SInce the disk can be set to spin down, and the battery protects against power outages, why is there a need for sleep? If I'm not doing any work and all my files are saved, I'm thinking I can just password protect and sleep my display. Are there any advantages or reasons to use sleep?

I'm thinking that "steady state" power to the board is better than "on and off" for the sake of the board and its components. When the machine is idle and the disk has spun down, power consumption is likely minimal. And yes, I'm typically connected to AC. If I were to go on battery, the battery settings would kick in with sleep.
Also, sleep prevents backup activity by programs like Carbon Copy Cloner.

Where Is The Sleep Setting?

In my Ipod mini i use the sleep settings every night before going to sleep. Now with my new ipod video, it does have sleep but has no selection of 15, 30, 60, 90 minutes. Is there anyway of turning it off after so many mimutes?

Assuming you have set the world clock to your particular time zone, then from the main menu select clock/select your time zone/select sleep timer, and there are your options.

Computer sleep setting

I have a LaCie external hard drive on auto so when I turn off the computer the drive automatically shuts off. My previous setting shut the monitor off after ten minutes but the hard drive would be on round the clock doing hourly backups. However, I just found the drive off, though I was able to awaken the computer merely by hitting a key on the keyboard.
Is it advisable to "never sleep" the computer for the sake of the drive staying awake for time machine purposes? I'm sure my electric bill won't jump by $50.00 a month.

If you're not using your Mac, there's really no point to keeping it awake just so Time Machine can do backups; nothing will be changed, so only a few small files updated by the system will get backed-up.
Apple recommends letting your Mac sleep, rather than powered-off, unless you won't be using it for "a few days." See Sleeping your Mac vs. Powering it Down.
Your LaCie should sleep or "spin down" after several minutes of inactivity.

Why does the put display to sleep setting put the hard drive to sleep

In the energy options (preferences) for power adapter, I have set the display to sleep after 1 minute but the hard drive is set to never. I do this when I am downloading but don't need to use the macbook. However, the macbook seems to go to sleep anyway - any idea why? Any new settings?
I've maintained these settings on my Power Book G4 and it puts the display to sleep but keeps the Power Book on while downloading.
Thanks

"Allow power button to put the computer to sleep" setting is not available but button does it anyway

This has never happened before. Computer stayed at gray screen with no progress wheel so I held the power button to shut it down. Since startup afterwards the power button sleeps the computer. There's no "allow power button to put the computer to sleep" choice available in Energy Saver but button does it anyway. Is there a defaults command that will fix it? Something else?

I've had Mavericks for a week and a half. I don't believe yesterday could have been the first time I used the power button in an attempt to get the Restart Sleep Cancel Shut Down box, but I've been around long enough to know that memory will fool you.

IPhone OI7 sleep setting

Prior to IO7, my iphone when inactive would go into what I call a sleep mode....dark screen....want to use it ....hit the home button, use the slide bar..(I don't passcode my phone). Now, it just appears to stay lit up all day. Runs the battery down. What can I do??

Sorry, there is no way to do that. You can suggest Apple add that as a feature here:

Display dims before sleep, no matter the setting

My MacBook will dim its screen (ie: reduce brightness) after about 10 seconds of idle time. I've read to stop this you need to uncheck the "dim display before sleep" checkbox under energy saver preferences. I've done this for both the power adapter and batery settings, but the display still dims! It will dim when running from the batery or the power adapter. It makes watching DVD's useless.
Has anyone else seen this? I find it annoying, but it's driving my wife crazy.

One option to try would be to change the login settings so that you are not automatically logged in when you start up to the computer. After you make this change, log out, log back in, toggle that display sleep setting on then back off and check the result.
Something else that might be worth a try...
First, I'm not sure what preferences, if any, will need to be reset after this. Also, I have not done this and do not know the result. As always, backup your stuff.
1. Go to the folder ./Library/Preferences/SystemConfiguration (not your Library folder but the one at the root level of your hard disk).
2. Drag the file named com.apple.PowerManagement.plist to the trash. You will be prompted to enter your admin password when you do this.
3. Restart.

Set DVD to Sleep Video Signal Sooner

Greetings!
PROBLEM:
My DVD project is burning in my LCD HDTV screen.
QUESTION:
Is there a way to make the DVD shutoff its video signal after a couple minutes of no activity (and override the player's sleep setting)?
I have two menus and three movies.
WHAT I'VE TRIED:
The forum search here seems to have changed, it searches the whole site (what's up with that?) so that was no help.
Menu pallet> General tab> End (set 2min for audio)> Duration (set 2min)> At End: Time Out (set 1sec)
The player led counter stops after the 2min as expected, but the menu stays on screen too long...

There is no command in VM of DVD player to go into sleep mode, however there is "exit" command to stop playback.
To use it you'd need to redesign your navigation scheme. For example you could make your main menu to automatically play the first movie after the menu itself have been played 3 times. So after 6 minutes of menu the movie will kick in, preventing your screen from burning-in.
The end jump of the movies would be set to another menu that times out to a script which would include the exit command. This will end the playback and after a defined time your player will go into sleep mode.

Mac Tower Pro 10.8.5 keeps going into sleep mode

Purchased from Apple, refurbished 2012 Mac Tower Pro. At the same time, purchased a new Dell U2713HM, 27" monitor.
Have been operating on this new system since about the first week of December 2013.
Issue:
The computer has constantly gone into sleep mode after a few minutes of no activity. I can have iTunes radio playing, but the system still goes into sleep mode. As I am typing and moving the curser, the machine stays awake.
This has caused much frustration because when it goes into auto sleep mode, it quits all programs that I am in, and when it does this, I lose all the work I had accomplished. It litterally closes everything and goes to sleep in about 2-3 minutes of no activity.
BTW: the computer and monitor have all its new OEM cables that came in the box, when I purchased the units.
Solutions attempted:
System Preferences — Energy Saver: computer sleep and display sleep set to "never" and unclicked the box "Put hard disks to sleep when possible."
Dell settings: Turned off all energy savers.
Results:
Nothing. Problem persists.

I apologize for the angst. The problem has cost too much money in lost time and material because when it would automatically shut down after a few minutes, all my work was lost.
I misunderstood the terms of the warranty. Thank you for your input and patience. Much appreciated. For the benefit of others that experience this with a new Mac that auto shuts down. Check the following:
1. Go to System Preferences.
2. Click on Security and Privacy.
3. Click on Advanced (bottom right corner)
4. If the first line is checked (Log out after 5 minutes of inactivity); uncheck it and then click OK button.
5. Be sure to click the lock before existing Security and Privacy.
Now the machine will cease shutting down programs to go into sleep mode as soon as machine is inactive for a few minutes.

What's a DVI-to-VGA connection have to do with sleep?

I've been experimenting with hooking my HDTV to my Mac Pro's 5870 video card. Currently I have my 27" ACD connected to one of the mini displayports (mDP) and a VGA, connected through an Apple VGA-to-mDP (active) adapter to the other mDP. When I want to use the TV I can connect the HDTV to the 5870's DVI connection with a (passive) HDMI-to-DVI adapter. It works. Indeed it works too well! Whether the TV is taking input from the computer or not the computer thinks the TV is a third monitor which can get very confusing when the mouse is accidentally moved off my ACD on to the TV (6 feet away) and I can't find the cursor. Another minor nit is that using the DVI means no audio can be passed on the HDMI so the computer speakers are used unless of course I hook up a separate audio connection.
I could get around the 3-monitor problem using SwitchResX but I prefer not to. I'm willing to simply manually connect and disconnect the HDMI cable on those few times I want stream stuff to the TV. But as an alternative I tried switching the TV and VGA connections, i.e., connect the TV to the mDP through a (passive) mDP-to-HDMI adapter and the VGA through a (passive) VGA-to-DVI adapter.
This second scheme also works. However because all the adapters are now passive the VGA will disconnect when the HDMI is plugged in. Ok. I can live with that and I understand the behavior due to the 3-monitor limitations of the 5xxx cards (i.e., active adapters required).
All the above was just background and context leading to the question I entitled this post with. Forget the HDMI connection. I have the ACD connected to its mDP and the VGA through the passive VGA-to-DVI adapter (i.e., the second scheme I described above). With this configuration my machine will not sleep on its own (i.e., at the time the energy saver specifies). I can "manually" put it to sleep ("Sleep" from the Apple menu). It just won't do it on its own (and none of the checkboxes in energy saver are checked -- wake for network for example -- and no active processes are running that would explain this behavior either).
Experimentation has shown that it is somehow related to using the VGA through the DVI. If I put my original configuration back (VGA-to-mDP) the machine will sleep on its own at the designated energy saver preference time.
What I don't understand is what's a DVI connection have to do with the energy saver sleep setting? The only remote possibility I can think of is perhaps the screen saver is running on both the VGA and ACD and an active VGA is sufficient to make the machine think there's activity when connected through the DVI (but not when connected through the mDP).
Of course none of this is really a serious problem. I'm only asking for academic interest.

I know I can do that but that's not the subject of this thread! I'm only asking why would a VGA connection to DVI keeps the computer from sleeping on its own.
And, oh, by the way, another audio alternative is something like this,
http://www.gefen.com/gefentv/gtvproduct.jsp?prod_id=5279
although this requires stringing a separate audio cable.

Monitor Not Going To Sleep on Mac Mini Server With Lion

Summary: I am attempting to configure a Mac Mini Server that runs OS X Lion. This machine was originally shipped with OS X Lion; it is not an upgrade. My current specific problem is that my Viewsonic VX2835wm monitor will not go to sleep when the minutes setting on the Display Sleep setting for Energy Saver has been reached. Instead, the screen goes blank for a couple of seconds and is replaced with a blank blue backlit monitor. (Ironcially, the display sleep menu cautions: "Never letting your display go to sleep may shorten its life".) I very much want and need the ability to have my monitor go to sleep so as to save energy and to extend the monitor's life for as long as possible.
Additional Background: I have had a couple of calls with Mac support and they have been unable to tell me whether this is a "design feature" or a flaw in the Lion OS because they have had no similar reports and they do not have the latest hardare available running Lion Server to test to see if this happens with other monitors. (They also, of course, don't have the VX2835wm monitor.)
I do, however, know the following:
(1) My HDMI monitor is connected to my Mac mini via a DVI KWM switch (ATEN CS1784) such that the HDMI output from my Mac is converted to DVI (using the DVI to HDMI converter that came with my Mac Mini) and is then run through the KVM and then converted back to HDMI (using a full pin DVI to HDMI cable). However, I have tested the monitor with a straight HDMI to HDMI cable running directly from the Mac Mini to the monitor and it has not changed anything.
(2) The Lion operating system correctly recognizes (in Hardware / Displays) the model of my ViewSonic monitor.
(3) I have a MacBook Pro running Leopard (OS X 10.5.8) that is connected to the same monitor through the same KVM switch (by way of a BookEndz docking station) which properly shuts down the monitor when there has been no activity for however many minutes are set in the Display Sleep setting under Energy Saver. (Indeed, all I want is the same functionality on my Mac Mini that I have enjoyed for the last two years with this MacBook Pro.)
(4) When fully connected to the KVM, if I switch from my Mac Mini to my MacBook Pro and my Mac Mini display goes to sleep while I am working on my MacBook Pro, when I switch back to the Mac Mini, my monitor backlight will be off (and the power light will be standby yellow rather than the blue on) until I wake my computer up by touching the mouse of keyboard. I wonder if this may mean that the Mac Mini's signalling of the change in status from on to standby is somehow dysfunctional.
(5) Shutting down the server functions (and other open applications) has no effect.
I would greatly appreciate feedback from anyone out there running a Mac Mini with Lion regarding whether or not their monitors go into standby mode when the Display Sleep time is reached (please note whether or not you are running the Server or Client version, whether or not it is a new install or upgrade, and what monitor you are using).
Thanks in advance to anyone who can help.

No, I didn't solve the problem. The monitor still goes to sleep with WIndows but not with my Mac Mini. About 8 months ago I basically wore out the power switch on my monitor so I bought a wireless power switch to shut it off at the outlet. The VX2835wm monitor itself is now starting to fail as well-- a couple of times it's gone through a weird sequence of flashing screen colors on power up and ended up in an overscan mode (that took me for ever to figure out how to fix). I have decided to replace my VX2835wm with a Dell u2412m once it fails for good partly because I really want to keep the 16:10 resolution (very hard to find these days) and partly because I want to see if a different make of monitor will go to sleep properly based upon my Mac Mini power down settings.
