Manually putting imac to sleep not working
This just started happening tonight with no new programs or hardware added anytime recently. I tried putting my imac to sleep & it goes through it's motion just to pop back up again. I tried it several times & it keeps doing it! What's going on?

What command or key combo are you using to put it to sleep?
Option-Command-Eject works for me. You have to hold the combo for about 1/2 second or more since the delay was put into the Eject key some time ago.

I can't seem to get my iMac (late 2009 model) into automatic sleep mode. If I manually put it into sleep I don't have any issues.
I used to solve the issue by running "PleaseSleep" application but that doesn't work anymore since Lion. I now want to fix the underlying problem.
I'm not running any weird background processes and in my energy saver settings I've tagged "put the hard disk to sleep when possible:, "allow power button to put computer to sleep" and "automatically reduce brigthness". All pretty standard.
Is there anyone who can give me some pointers ?Today I solved the same problem for my iMac running Snow Leopard. See https://discussions.apple.com/thread/3008791#15947706. The method may help you, too.
For me it was the DynDNS Updater preventing my iMac from automatically entering sleep mode.
To my knowledge the cause of this sleep problem can only be a peripheral device or a process. So I suggest to first unplug all peripherals and test whether that's the cause. If not, I suggest to terminate one process after another and to test automatic entering of sleep mode after each. Start with user processes; continue with system process if necessary.
At least that's the way I found the offending process. Fortunately, I was able to change the configuration of that process to allow again automatic entering of sleep mode.
Good luck! -
Bluetooth and sleep not working
MacBook bluetooth "not available" at the same time as sleep not working (the cd drive wakes up and puts it out of sleep after about 20s). These two faults occur together and are intermittent, though increasing in frequency. I have tried all the fixes (flashing, power reset etc) listed, but none are working, e.g. an earlier post is below. Anyone with any clues - I'm in guarantee but would rather not have people pulling the machine to pieces if I don't need to.
Thanks
http://discussions.apple.com/message.jspa?messageID=4571577#4571577PS. to the above, just worked out that it only happens when I'm connected to mains power (not on battery) so i guess it's some hardware glitch...

I have an iMac that is not working. The screen stays black when I turn it on and it won't respond to any keyboard strokes. I have a cd stuck in the computer. How do I get it out?
Hello
Try this
plug a WIERED mouse , start up your imac , hold on mouse buttons for 30-40 second at least by chance cd could be ejected

Hello,
Since the 5.1 update, my Apple TV 2 has no audio after it wakes from sleep mode. To get audio back I need to go to settings and manually put it to sleep then wake it up. Once I do this I have audio. I have restarted the Apple TV as well as me modem and router. I have searched the boards and cannot find a solution. Please help.mrdctaylor wrote:

Put iMac to Sleep, Warm in the AM
Before I go to bed each night, I manually put my iMac to Sleep from the Apple menu. Within a few seconds it shuts down and makes no noise (no fans).
Most mornings however, when I awake, I can hear the fans spinning (primarily the hard disk fan using Activity Monitor), and the top of the computer is warm. When these fans come on I cannot tell, but I'm pretty sure the computer doesn't light/wake up, show the desktop on both monitors, and then go back to screen saving mode and then eventually the screens go dark but the fans still run and the computer stays warm (e.g. not sleeping, just the displays are black).
How do I put the computer to sleep at night, so NOTHING runs (no fans) and the computer is cold in the morning?
Thanks.Nothings happening, tried the mouse, tried the keyboard, nothing. I followed the instructions for resetting the SMC and the only thing I get is the light sound I describbed in my earlier message. The more i listen I don't think it's the cd drive, I feel like that would be a little louder than the sound I hear. What I'm hearing sounds like a light spinning sound almost like the hard drive when yo click the keyboard to wake it up, except it keeps doing it over and over again until I unplug the mac. When I plug it back in, it will not make the sound until I press the power button on the back.

Power off after putting iMac to Sleep
Have you ever experienced this?
Put you iMac to Sleep and it powers down - not a shut down, but the power goes off - no blinking light, no whirring of the hard drive, no sign of life!
I have read and performed many of the tips regarding NVRAM, SMU, PMU, etc. resets. None have worked.
Situation 1-
Use the 'sleep' command - moments after the machine powers off.
Situation 2 -
iMac screen saver will run for a short time, then screen goes blank, the power light illuminates, the fan spins full speed, and the machine is totally unresponsive to mice clicks or movements, or keyboard entries.
Situation 3 -
Sometimes upon power up, the iMac doesn't start, but you can hear a faint buzz sound from the back of the machine. Similar to audio hum.
These problems occur whether or not other devices are connected to the iMac.
Connections-
Standard USB devices - mice, card reader,
Bluetooth keyboard
Ehternet
Power Settings-
Screen saver 5 minutes
Energy Saver - to sleep when inactive - 15 minutes, display to sleep - 15 minutes.
Various other settings tried with no change in problem.
I suspect the power supply. What's your opinion?

I began experiencing the same thing this week (two days ago). I also tried repairing permissions, resetting SMU, and removing the iTunes receipts (Library/Receipts) since this is what caused an earlier failure to sleep. The difference is then the computer would not sleep, now it shuts off instead of sleeping.

I have experienced this (Sit 3) as well with my LaCie firewire drive connected, sometimes. I have found that powering off the LaCie resolves this, as does unplugging it.

Suspend / Sleep not working anymore
Hi all,
for some short time now, my Mac Mini (Intel) doesn't go to suspend anymore. When I try to put it to sleep with the remote control, it powers down as expected but immediatly powers on again.
I tried to look in the logs (sudo dmesg) and all I could find was som entry from bluetooth. Bluetooth is disabled, though. The only bluetooth thingy running is the bluetooth applikation in the menubar.
Am I missing something?
Cold-1Hi Pos,
thanks for the fast reply. I tried everything in your list. I even disabled almost all widgets, killed all unneccessary processes (SmartMon, Quickslver, iCal, ...), disconnected all USB devices, but no luck. I also looked at the log again and I must admit that I just went through it to fast. It is not the bluetooth device that causes the awake, it's... I just don't know.
here is an exerpt:

The state change from sleep to awake is really instantaniously.
The strange thing is, the sleeping mode that kicks in with the screensaver works flawlessly, only the sleeping mode activated by the remote or the Apple menu does not.
I am very close to reinstall everything.

Systemd hybrid-sleep not working
Hi!
Today i finally tried out (only for curiosity) hybrid-sleep, and i discovered it is not working.
I'm not using testing repo. So, systemd 196 should be able to hybrid-sleep.
First problem: i need to put my password to hybrid-sleep, while for suspend and hibernate that is not necessary.
Second problem: as far as i understand, hybrid-sleep should be a normal suspend, but in background the netbook should suspend to disk too, in event of lack of energy. Is this correct? Well, on my netbook, it only hibernates, as if i did a "systemctl hibernate".
journalctl
dic 02 18:48:33 arch systemd-sleep[4421]: Hibernating and suspending system...
dic 02 18:49:09 arch systemd-sleep[4421]: System thawed.
But it is not "hibernating and suspending", it is only hibernated.
By the way, i'm not using pm-utils.
Any hint?
Thanks!I can reproduce this behaviour with systemd-196-2. systemctl hybrid-sleep just hibernates and powers off. Further investigation of this issue brought the following issues:
systemctl suspend works as expected.
systemctl hibernate works also.
Disabling hibernation (by disabling the swap and resume partition) leads to suspend to ram with the hybrid-sleep command.
Circumventing systemd does the job and correctly hibernates AND suspends:
echo suspend > /sys/power/disk; echo disk > /sys/power/state
So I guess the kernel part of hybrid-sleep and the hardware work correctly and somehow the systemd-hybrid-sleep.service does not work. The service file has the line:
ExecStart=/usr/lib/systemd/systemd-sleep hybrid-sleep
which seems to be the relevant command. -
Since updating my Late 2010 iMac to Moutain Lion the sleep function does not work correctly. They system keep waking up for no reason. The monitor comes comes day or night. I cannot figure out a fix or work around. Any ideas?
Please read this whole message before doing anything. This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it. Step 1 The purpose of this step is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.” While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin. Test while logged in as Guest. Same problem(s)? After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it. *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing. Step 2 The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Test while in safe mode. Same problem(s)? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2. -
Hi -- I recently installed windows vista on my T42p. It works fine except that the fn+f3 and fn+f4 functions do not work as expected. Before installing the hotkeys driver, the fn+f4 function worked correctly while f3 did not (going to sleep worked, turning the monitor off did not). I then installed the recommended hotkeys driver. Now fn+f4 makes the monitor turn off while f3 does nothing ... fn+f4 is supposed to put the laptop to sleep. On top of this, if i select "sleep" from the start menu, the computer turns the monitor off instead of going to sleep.
Presumably, the sleep button could still be telling the computer to go to sleep, but the actual operation of going to sleep is now broken? Just a guess. Anyways -- anyone know how to resolve this so that fn+f3 turns my monitor off and fn+f4 puts my computer to sleep?I've too this problem, but more, my sound mute wasn't worked (for deblock, but it can block it few second before...) 5 days in 5-6 instalation of three version of winxp: winxp ru x64 sp2, winxp es/ru sp3 x32.
eventually I've found and ran "TPOSDSVC.exe" in instalation directory and it give an opportunity deblocking the sound volume!!!!!!!!!!!! and I don't need more functions
volume levels and brightness adjustment worked well without OSD (before I ran TPOSDSVC.exe) and with OSD.
and now I don't know worked this bustered sound driver in winxp x64.

Hi I was wondering is there a way to keep ichat running even if u decide to put your computer to sleep.
Hi Jeff,
Nope.
A Mac's default action is to disconnect the Mac from the internet if not active (awake).
There was an Add-on for Panther iChat that does not work with Tiger that allowed you to post a permanent Away message when you were offline.
If you use Fast User Switching there is a setting in the General section of iChat preferences for making appear that you are Away when in fact you are not connected from the Mac USer. I hav not noticed that this effects the Sleep fuction at all in the way you describe.
Any Application that is open when the copmuter goes to sleep is not actually quit and in that sense is "open" but I don't think this is what you meant.
Because of the "restart"/Waking order of Apps and re-establishing the connection for the internet can cause some problems in iChat recognising that the connction is there.

Put imac to Sleep or Shut Down
What's up guys
I'm just wondering, I use Logic pro
a lot and I would like have quick
access when I have a creative urge.
How often should I shut down my imac
as apposed to putting it to sleep?Several schools of thought:
1) never shut it off (but it's OK to let the display sleep, i.e., go to screen saver, but never let the computer or the hard drives go to sleep)
2) turn it on and off as needed
3) put the computer to sleep (including display and hard drives) when not being used
Considerations:
1) "always on" --- if having immediate access to your computer to get down creative ideas ASAP is important then there should be no other factors to consider.
2) "on/off as needed" -- the exact opposite of #1
3) "sleep" -- a happy medium? It depends... Waking a computer from sleep still means that you have to wait a while before you can start to record. You should experiment with your system to see how successfully it wakes up after being put to sleep before committing to this practice. Sometimes a system won't wake up from sleep and you'll have to re-boot anyway.
