Not going to sleep

Hi,
I have an Imac freshly reinstalled with OS X.4.9. Since then, I realized that when the sleep mode get in, the screen goes black but everything still running (fans and hardisk) instead of going to sleep. Does it is a bug with 4.9 or I would need to reinstall?
Thanks

Welcome to Discussions - Are you sure that you have designated a time for your computer to sleep in System Preferences>Energy Saver? Sometime, an update will alter previously selected times.

Computer not going to sleep when lid closed

My wife's new MacBook Air has a couple of problems we can't figure out. First sometimes the computer is not going to sleep when lid is closed and when we lift the lid everything is frozen.
Second, the user Library folder is not seeable in her user account. I know it's there because on the side bar there's a short cut to Preferences folder which we can open.
Strange behavior.
Thanks,
Ron

Ron,
The user library folder (~/Library/) is hidden by default in Lion. I assume Apple doesn't want people mucking around with the sensitive files in there. So this is normal behavior.
As for the freezing issue, I would suggest you reset your power management and perform a safe boot to clear out caches. You should also see if the issue persists after disconnecting USB perhipherals.
Here's how:
Power Management:
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Safe Boot:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

MBP not going to sleep

I have had my MacBook Pro for a little over a week now and i am noticing that it is not going to sleep according to my energy saver preferences, or at all for that matter. Any ideas?

Something must be preventing it going into the appropriate sleep mode; either some software running or a lack of space for the sleepimage file (most unlikely at this point). Run /Utilities/Console, click 'All Messages' top left and then select Sleep from the Apple menu top left - there should be some lines in the Console Log that will give a clue about what's going on (post them here if you like).

IPod not going to sleep correctly

Hi there,
I am having an issue with my iPod 5G not going to sleep correctly. When I select the "Sleep" function on the menu screen the iPod with stop responding to the wheel, as per normal, BUT the screen only fades and does not blank itself completely. I can still see the menu items.
Is this right? I though the screen blanks completely, to save on battery power.
Advice and thoughts needed...cheers
iPod 30Gb 5G Windows XP

Hi, I have managed to change the battery of my Ipod
mini, but still after the Ipod is fully charged the
battery life still lasts only a few hours....
My assumption after reading all the technical
documents, is that even though the Ipod mini appears
to go to sleep (either by itself or after the play /
pause) button is pressed for a few seconds, that in
fact the Ipod isn't a sleep and the battery runs
down....
I have updated to the latest 1.4.1. software... only
recently happened, and replaced the battery (but
perhaps it didn't need it).
And it's 14 months old so out of warranty...
Does anyone know of issues with sleep mode not
working correctly? Is there a software fix for
this????
Cheers
I think I'm having the same problem - let me know if you find an answer and likewise I'll do the same. Is going to sleep the same as turning off? Mine doesn't even turn off when I press down the play/pause button!

MacBook not going to sleep when connected to WiFi

Hi there,
my MacBook 3,1 is not going to sleep as long as it is connected to WiFi.
It starts the process of going to sleep as my VNC connection gets dropped but it stays awake. I can easily reconnect.
Everthing else is working fine. Any suggestions?

Hello everyone,
I'm facing the same syptom. I tried many things and now havw to live with putting the MacBook to slee by hand. I had some other issues just before that:
1: The MB returned randomly from sleep while being closed. That was annoying. I think it was fixed after installing smart sleep and doing some cleanup in the preference files.
2: Then I was put "randomly" to sleep. I figured that came from overheating the processor (thus I'm gld it went to sleep). The fan speed control was set to constantly 2000 rpm. Installing fanControl helped.
3: Lid closing did not init the sleep mode and the backlight is not turning off. Niether does it wake up on opening when I put it io sleep manually (I have to press a key).
The sensor for closing the lid seems to work, if it is the same which controls the maximum brightnes of the sleep indicator light (pulsing). It is darker when the lid is closed.
I wonder if there is some settings tool.
Besides I think the issues started after the Software updates around 12th of dec. 2008, with MacOS10.5.6 and the EFI & SMC firmware updates.
I'm eager to get answers.
Kid regards, Ralf.

External hard drives not going to sleep

External HDs (I have two) connected to my 2.26 unibody macbook are not going to sleep even though I have the appropriate check box selected in System Prefs. Running 10.6.8. Connected through the USB ports in my 23" cinema display. Any thoughts or suggestions?

Lion may not be able to put them to sleep (as it can internal drives). The drives often come with drive management software to do that (check that it is Mac OS compatible). I have two Segate drives that backup my server and then sleep, but that is managed by the managment software.

Just Updated to 10.5.2 on Feb 10, 2008, Display not going to sleep anymore

Greetings:
I am running on a Macintosh G4 Graphite (which has been heavily upgraded to a G4 1.8 Ghz processor (Sonnet Tech Encore) and it has 1 GB RAM and an upgraded ATI Radeon 9200 Mac Edition video card). Under 10.4 -10.5.1 everything worked fine.
I have my Power management settings set to put the display to sleep every 30 mintues and changed to 3 mins to check if something else was up.. but the display is definitely NOT going to sleep any more.
Any thoughts and is anyone else having this issue?
I have not yet trashed the preferences file, mainly because I am not sure where it lives.
Thanks,
Mike

Hello All Again:
Just wanted to update you on how I fixed the problem. Not sure what specifically in the combination fixed it, but it does now work
First I opened System Prefs > Energy Saver and hit the set to defaults button. I then exited System Prefs.
I then went into Terminal and ran pmset displaysleep 30 and exited terminal.
Lastly, I went into System Prefs > Energy Saver and selected 3 minutes. Exited System Prefs and waited and lo and behold it worked. So I rebooted my system and then set the timer back to 30 mins and it has been working again so far.
I suspect that the pmset from terminal may have refreshed something in the prefs file someplace, but again it was just something in that string of things I did that worked.

Computer hanging on closing lid and not going to sleep, indicator does not blink

i have a 1 month old Macbook Pro 13" i5 with 4Gb memory.
when i am closing the lid the computer is not going to sleep, hard drive continues to spin and power indicator does not blink and it remains solid.
on opening the lid again screen keep blank and does not show anything while i can hear spinning of hard drive. than i have to forcefully shut off the computer by pressing power key and than computer starts after that.
Apple support told me to press shift+control+option+power and than start computer, it fixed the problem only once and they told me to do it again when it comes again. but write now i am getting it everytime.

Hi guys -
First off make sure you don't have 'Wake for ethernet access...' enabled in System Preferences/Energy Saver/Options - I'd also run Disc Utility and repair your permissions as well. OS X requires 'maintenance routines' to be performed on a certain basis and you can use this free application to help you with that...Onyx.
Check the obvious as well - that you don't have any applications that might keep your Macbook awake ...some printer utilities do this for example.
After all this shut down and restart and hopefully things will be better - if not, there may be a chance that the mechanical parts that put your computer to sleep may be at fault ...and you'll need to visit an Apple dealer to verify this.
Hope some of this helps.

PC is not going to sleep or shut down after upgrade to Windows10

Hello,I upgraded my laptop from win 8.1 to win 10.Now when I close the lid or press the power button, the computer turns the screen off, turns the WIFI off, no more hard disk activity but it is not going to sleep.Also when I shut it down it goes throught the same procedure but never turns off.To start again, I have to keep pressing the power button to turn it off, then turn it on again.I did the powercfg - energy and got this in the report, "USB Suspend:USB Device not Entering Selective Suspend"When the computer had just started, I don't get that message, it also goes to sleep and shuts down normally, while later, I get this message in the report and no longer sleeps or shuts down.Any suggestion ??Thanks

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.

External displays not going to sleep?

Environment: Early 2013 MBP Retina 15'', OSX 10.8.5, two external HP LP2475w monitors connected via DP-DVI adaptors. The monitors are correctly recognized in the system report.
I am not running a screen saver, and in the Energy Saver preferences, I have set the display to go to sleep at 15minutes (long before the computer goes to sleep).
The built-in display indeed goes to sleep at the predetermined time, but the external monitors simply get a black screen, they don't actually go to sleep (indicator light is green, the backlight is still on). There is no problem with the monitors, they correctly go to sleep under both Windows and Linux.
My theories:
(a) vesa information about how to turn the monitors off is incorrect
(b) something about the mini displayport to dvi adaptor kills that signal
(c) there is no way to turn off external monitors, I'll have to live with this
Help?
Thanks!

exactly the same here. 2011+dell 24"
i called apple hotline and they did this with me:
http://support.apple.com/kb/HT3964
and
http://support.apple.com/kb/HT1379
after this the external monitor went to sleep flawless. ... but as soon as some usb-ports are busy (with an external drive or something) - even when everything falls asleep the external monitor keeps on again.
but a least without the usb the monitor now falls asleep too - so there is hope!

CoreDuo Mini not going to sleep

Sorry for the cross-post - still in the process of getting familiar with posting here and the message below got posted under displays...
After installing the latest firmware 1.01 on my Intel CoreDuo Mini it no longer goes to sleep although the screen goes black at the prescribed time. The reason I know it is not actually asleep is the little light in the front which usually changes intensity when the computer is asleep.
I now have to press the button in the back to 'force' it to go to sleep.
Has anybody else noticed this??
Peter

My Mini (same config as yours) goes to sleep without any problems, even after applying the firmware update.
The pity is that 1/3 of the time it won't wake up ...

Monitor not going to sleep when close my lid to MacBook Pro

Hi. I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more. Please help.

Sounds like the system is going into Clamshell mode. Here's some info on that mode.
One workaround would be to disconnect line voltage as that's required for clamshell mode, there may be others.

Mac not going to sleep - anyone has a fix?

I just deleted (again for the 4th time this week) the Address Book Source files (Linc's fix). Will post again later - hopefully will find a permanent fix for that, once the problem pops up again.
This is what remains when I type pmset -g assertions in Terminal after deleting the Address Book files. Even if nothing appears to prevent sleep, yet after 5min, laptop was not sleeping and took many times pressing 'Enter' and 2min of intense computer work to 'wake' from a 'not sleeping'-stuck state. I used to hit 'sleep' or close the lid, for years (!!!) and now it's a problem after another. Any ideas what's going on here? Nothing is connected to USB. Bluetooth is off. But wireless is on. Even Time Machine is off.
Yesterday I booted in safe mode and restarted (again a fix provided by Linc - I was really hopeful it would reset some files and fix it for good!!!). And today... tada! Again. Another solution? I need to close this laptop, it goes to sleep within a second and I put it in my bag and go. Am I too hopeful?

I usually have the bluetooth on. And turn off the mouse, pack up and go. Never used to be a problem. Turned bluetooth off for this test.
