OS X V10.7 Lion :: Imac Intel 27 In Does Not Wake From Sleep?
Apr 2, 2012
Ever since I bought and downloaded OS Lion, whenever I put my mac to sleep or it goes to sleep on its own it occasionally won't wake up from sleep. It has to be manually rebooted. Is anyone familiar with this problem. Apple must know about it by now. I'm not lugging my 27" iMac into the apple store to have them look at it unless it won't reboot. Hoping it doesn't come to that...anyone familiar with this or have ideas on how to fix it? I don't know if it's a 3rd party software issue or just the OS.
My iMac is about 4 months old and about twice a month after sleeping overnight the computer will not wake up. After several attempts pressing keys on the keyboard and clicking on the mouse, I have to unplug the Mac and then press the start button on the back
Imac completely dead and not able to wake up after putting to sleep.This is a new error on top of many others.Very annoying one has to reset and restart to overcome something that is supposed to work o.k?
Having some trouble with my iMac (the version right before the intel iMacs came out. further info can be provided if needed). Running all the latest software updates etc. When I put the iMac to sleep, it goes off as normal. With the usual white light. However, when coming to wake the iMac it won't respond to the keyboard or mouse. I have to shut it down at the power button, and then turn it back on.
Does anyone know if it's possible yet to wake an iMac from sleep via the internet? I'd like to use remote login via SSH to an iMac from an ibook, but it is quite useless unless I can wake the iMac from the internet.
I have an older iMac (MA589LL) that I recently upgraded to 4GB and Snow Leopard which is running beautifully. I do have an issue with it though, and it's been occurring for a while: Whenever the machine goes to sleep and I wake it up, the monitor turns on just fine but after about 5 seconds it goes back to sleep. I have to repeat this about 3 times and then it is fine. It's an annoying issue but not a deal breaker as I can just turn it off. I searched for sleep issues/turn off issues and have not found anything.
NOTE: Issue occurred before the upgrades. I've also tried resetting the PRAM and NVRAM. I have also used different keyboards/mouses.
When my computer goes to sleep it will not wake up, and I have to shut down using the power button on the back and then restart. I called support and they advised me that this only happened when the computer went to sleep on it's opwn but not when you manually put it to sleep, But that proved not to be true. It will not wake up under either situation? The support persontold me to logonto applke and re-install the sytem software which I have done but that did not cure the problem either. I have my preference set to never sleep. I am ar]t a loss as to what to do now as when it goes to sleep or I put it to sleep i sometimes will not start up even after shutting down and restarting.I am on 10.7.2?
My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark.
My Mac would not turn on this morning from sleep mode. I pressed the power button and nothing. Then I did it again and heard the fan shut off inside so I tried again and up it came. Also I cannot wake my Mac up unless I press the power button. I used to press any key on the keyboard or move the mouse and it would wake up, but now that doens't work. I don't know if this could be a reason, but my mother has a horrible habit of unplugging it when it storms. It's always asleep and I've told her not to do that and to make sure it's turned off before ripping the cord from the wall. But she continues to do it when it storms.
For the past few months i've been having issues with my imac 2.66Ghz 24 inch. I'd say almost half the time when i put my imac to sleep it doesnt wake up no matter how many keys i press and it just stays stuck on a black screen. I know that when you put the computer to sleep you hear absolutely no noise however in this case i hear a slight fan noise despite it 'sleeping'. When this happens i always have to use the on/off button to do a reset. What seems to be the issue here??
Every now and then, my 2010 27" iMac won't wake up from sleep by pressing a button on the keyboard or the Magic Trackpad. The computer won't even respond to a tap of the power button so I end up having to hold it down for a hard reset.
It seems like this only happens when the Mac sleeps with an application running (usually EyeTV 3). Is it an issue where the bluetooth keyboard and trackpad aren't communicating with the Mac properly?
I had my iMac 27" for two months, and I am very pleased with the machine - except for one thing. When I put it to sleep, the computer just go to sleep in a couple of hours and then return to no-sleep. It started just after I bought the computer. I always set my computer to sleep, and so I did even then - but the first thing I noticed was that the hard drive was started during the first night. Strangely, I thought and put it to sleep again. Then I fell asleep, but when I woke up next morning the computer was on.
Then I wrote on another forum and they told me to check out: Wake up in network access, which I did. And then it got better. Now the computer has been without problems for a month, but then a few days ago it came back. This box is still check, so it can not have anything to do with it this time. I've also tried turning off all programs, the keyboard and mouse when it has gone down to sleep, but it still restarted. What is wrong? Please run with Sleep and it is a program that will prevent the computer to wake from sleep, but not:

What can I do? Can I submit it to Applecare? Some peoples say you do not have to turn off a Mac, but I want to put it to sleep, but it starts up the next day. I've also restarted the SMC, but it gave no effect.
After my 27" i7 wakes up from a long sleep (roughly over 1.5 hours), something very odd goes on with my color profile and/or screen. Approx. 5 second or so after waking, the screen color appears to wash out quite a bit. You certainly have to be quick to notice it, but something is definitely going on.
This problem started after a power surge a few weeks ago. The surge protector fried, but seemed to save the computer in the process. Symptoms are:If the Mac goes to sleep, the fans eventually go in hyperspeed mode and it's impossible to wake.Boot time is over 6 minutes. 1.5 minutes on the gray Apple, then 5 minutes on blue screen.In verbose mode, I get some IOKitWaitQuiet error just before the blue screenI repaired permissions, checked the disk with Disk Utility, and zapped the PRAM. Here's the console report of a restart. The blue screen was between 8 and 8:05.

For some unknown reason I will put my mac to sleep and at sometimes it will wake up without any command to wake up - why this happens and how to correct it?
My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

For the past few weeks it has been going to a black screen when trying to wake it up from sleep. Either I've put it through too much work lately editing all these photos and its really tired. So, often it wakes up normally and functions fine, well, not really. It is seemingly very slow. It requires a lot of time (more than before) to open up a program or it gives me the "spinning wheel of death" when trying to go to a different page on the internet or open up a folder on my desktop. Amongst other things that require it to think. So It's just a lot slower in general than before.
I'm experiencing very annoying sleep/wakeup problems with Mid 2007 iMac. I think it started after 10.5.6 update.
1. iMac does not go to sleep according to the Energy saving settings, this was actually from the day one. It goes to screen saver, display sleep, but not complete sleep. 2. Since automatic sleeping does not work, I put it to sleep manually by pressing Power button. but in this case it sleeps so deep, that it does not wakeup. The only way to bring it back is to hold the Power button to complete OFF and then power back UP.
I tried, PRAM and permissions tricks, nothing seem to help.
i just bought the imac 21.5 inch with ati radeon 4670 and the base spec. after few hours of playing with this new toy. i realise that when you press the shutdown button, it will put the imac to sleep instead of showing the shutdown/restart option that i have on my macbook. Is there any way to make it work like a macbook power button. secondly, whenever my imac wake up after sleeping, the fan will run faster and automatically went to sleep again. this issue just keep repeating itself. i have no choice but to shutdown the imac and boot up again. Thirdly, i try the machine on WoW and i realise that the sound is rather choppy
I just purchased a set of Mushkin Apple 8GB (2x4GB) DDR3 1333MHz SODIMM 9-9-9-24 (976647A) RAM for my mid 2011 27" iMac and everything ran great for a few days. I was able to sleep and wake the machine with no problems. Last night I was doing some graphic intensive work on my machine and when I had finished, the fans were still running high but I was going to bed so I put the machine to sleep. Normally the fans would stop at this point but they kept running. I assumed the machine was still hot so it was just cooling after sleeping. The next morning the machine would not wake. I had to do a hard reset to get it to boot up again I tried resetting the SMC and PRAM but it still doesn't wake from sleep. Am I have issues with my RAM?
My iMac becomes totally unresponsive after sleeping for any length of time. It will not wake from sleep, even if I connect a wired keyboard; and it will not shut down or restart until I reset the SMC by unplugging the comptuer from power for 15-30 seconds. I can restart the computer after resetting the SMC, but the same thing happens every time the computer goes to sleep.
I have also set the computer sleep slider to "never" and reset the PRAM. Although people have been complaining about this issue for months, Apple's Lion updates have not addressed this issue.
