IMac i7 sleep problems

So I've been pretty happy with my iMac i7 so far but in the last few days, I've been having some issues with the sleep function.
I first noticed an issue where I couldn't wake my iMac back up from sleep. The screen wouldn't turn on after pressing a bunch of buttons on the keyboard or clicking the mouse and I would end up having to reboot the computer entirely.
The second issue with the sleep function happened this morning. I tried to manually sleep my iMac before going to work and it just refused to sleep. The automatic sleep seemed like it still worked however as the computer went to sleep later (after a few minutes of inactivity).
They're not major issues but I am definitely concerned...anyone else have (or had) this problem?

As the first steps, try resetting PRAM
http://support.apple.com/kb/HT1379
and if that does not help, reset SMC
http://support.apple.com/kb/HT1543
which is basically disconnecting all cables and power, and reconnecting using a precise procedure. When you reconnect the power, consider where it is plugged in. If it is through an over-crowded or old power strip (surge suppressor), you might want to try connecting it directly to the wall outlet (or by itself through a new power strip), at least initially. Power it up with nothing connected, except for the power cord. Then, connect just the standard keyboard/mouse (if not wireless); use it that way for a while. Try doing things that did not work properly before. If the problems do not recur, you can start adding your peripheral (USB/FireWire) devices; do it one by one if possible. If the problem recurs, note what device was added last. Peripheral devices can interfere with sleep, wake, shutdown, and startup.

HT2412 iMac "deep sleep" problem

Hi, I have a iMac 27" Late 2012 and it keeps going in "deep sleep" when I leave it unattended during the day. When I come back, I have to wait for my mac to load the saved state which is quite long. I had many macs in my life and it's the first time I encounter the problem. I've seen that sleep mode before when my MacBook would be out of battery, but never on a desktop... My energy saver settings are set to never sleep (computer) and 15 minutes (display). My setting in Privacy/Advanced/Log out after XX min of inactivity is also off. I checked my hibernation mode in the terminal and it is set to 0. Out of ideas. Anyone ?
Thank you !

I have the same problem on my black MacBook. My problem is intermittent. Sometimes restart works; sometimes I'll select restart, but after the logout it never really shuts down. Black screen, glowing status indicator, completely unresponsive. I've also left it overnight with no change. The only "fix" is to do a hard shut down with the power button, whereupon I'm presented with the annoying "computer wasn't shut down properly" message on startup. No kidding! But no matter how many times I report it, no response.
I've tried resetting the power manager, I've tried zapping the pram. I've tried reinstalling the system -- I just nuked and paved this weekend, with no change. So either it's a hardware problem, or something fundamentally wrong with the OS. But since I don't hear a lot of people complaining about this one, that makes me think it's specific to my (and your) computer...
I called Apple about it while still under warranty, but got no helpful suggestions. The nearest apple store is 7 hours away, so I can't just pop in and show off my problem

2010 iMac having sleep problems

I have a late-2010 21.5" iMac (3.2GHz Intel Core i3 / 8GB RAM) running OS X 10.9.2
It's always been very well behaved and never had any problems. However, since upgrading to Mavericks recently, it's been having some sleeping issues.
Whilst asleep, the computer will 'semi wake up' – basically I can hear the hard drive whirr into life, but the screen remains off. It does this for about 1 minute, then goes back to sleep again.
It didn't bother me, I assumed it was a new feature like Power Nap (?), where the mac was doing something like waking up to check emails in the background, without properly waking up.
However, recently, the mac will stay in this half-awake state, and there's nothing I can do. So the hard drive is spinning, the mac is getting really hot, but the screen is off. It remains unresponsive to any keyboard or mouse input. It stays like this for as long as possible – until I hold down the power button to force a shut down.
It's becoming frequent. Should I be worried? Anything I can try to fix it? I was considering a blank Mavericks install...
Thanks

Intel iMac sleep problem, need help !

My 17" Intel iMac has sleep problem past few days.
I use the Ctrl+Eject on the keyboard to put my iMac to sleep and it only needs 3 to 5 sec before.
But now I use same method, it got 30 sec. to sleep; same result thru Apple menu>sleep.
Used Onyx & repair permissions, still no change.
Anyone know what's the problem, how to fix it?
Plz help!
Thx!

Danlam,
A simple SMC (System Management Controller) reset is known to resolve a lot of sleep/wake related issues.
Here's how to do the reset:
- From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
- Unplug all cables from the computer, including the power cord and any display cables.
- Wait at least 15 seconds.
- Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
- Press the power button on the back to start up your computer.
Follow this link to the Apple Article that describes the SMC and how to reset it in more detail: http://docs.info.apple.com/article.html?artnum=303446
Hope this helps you out.

Possible reason for the iMac G5 with 10.4.3 Sleep Problems

Ok first off let me say that I got this new iMac G5 20" about 4 days ago. It's wonderful. If anyone out there is holding out for the intel machines, don't wait, get a G5. It's a fantastic machine. Now on to the meat of the subject. The story goes like this; I hooked up my Plextor PVR with eyeTV to my iMac to see how well it would do (been using it with a P4 Windoze XP machine and my iBook G4 14" with no problems). It worked just great. No problems with the iMac, the PVR or any of my other addons (including the boatload of software I migrated over from the iBook). So I set up EyeTV to record some stuff while I was asleep. It's supposed to wake up the Mac, record the shows then the Mac goes back to sleep. Easy huh? Well the wakeup, record part went just fine but the Mac wouldn't go back to sleep. Perplexed (actually thrilled, this is where I have my most fun with new machines, figuring out why they aren't working correctly) I did all the standard "I can't get my Mac to sleep automatically" things. You know, blow away all the plist files that have anything to do with powermanagement and autowake, reset NVRAM from OF, reset the PRAM (3 times just like the old days), reset the SMU, blow away all the Bluetooth plist files, etc, etc. Did them all, don't suggest any, I did them all I swear, really. I've been through this kind of thing before. One big difference with this iMac. Nothing and I mean nothing would work to fix the problem. The only way the bad boy would sleep is by hitting the Power button for a second or selecting "Sleep" from the Apple menu. Hmmmm. Spent the better part of a morning reading every thread here about peoples problems like mine. One post and I mean exactly one had something I hadn't tried. I rebooted the Mac in Safe Mode (hold the shift key down while it boots until you get the login screen with the red text "Safe Mode".) I forgot that OSX even did that. Logged in as myself (normal login but still in safe mode) and low and behold the thing would sleep automatically! I repeated this (boot in normal mode, boot in safe mode) many times. Every single time the Mac would sleep from safe mode but not from normal mode. Tells me it's software not hardware. In each mode I run "Activity Monitor" and save a list of the running processes to a text file. Now compare them and shutdown each process that is different one at a time. To make this story somewhat shorter (heh) I finally found that I could consistantly make the machine sleep or not sleep by killing the "mdimport" process and restarting it. This has to do with Spotlight. To be exact, it's the process that imports Metadata into Spotlights data list (I'm no expert, have a basic understanding of this). So on a hunch I ran the terminal and entered the command to delete then rebuild Spotlights databases, "mdutil -E /". Then I let Spotlight rebuild that databases and rebooted. Guess what? The iMac sleeps perfectly now, go figure. I did this once so far and the Mac has been working correctly now for about 5 hours. I've got a feeling that the problem will come back. Especially if it's an inherent problem in Spotlight and the 10.4.3 upgrade. I don't seem to have this problem with 10.4 or earlier. Long post I know but I thought it could help someone out. Please post any comments. I'd like to know if what I did is coincidence (I really don't think so since I reproduced it many times) or not.

iBook G4 1Gig, iMac G5 2.1 Gig, iMac 266 Mac OS X (10.4.3) iMac 266 running 10.3.6, been using Macs since the '80s

Right guy's i to have researched this problem
concerning my auto sleep problem.I started off by
following Joeaux's original post by safe
booting,noting what was running in the activity
monitor,booting normaly and again noting what was
running now.I eliminated the same processes that were
running from both boots, and then started quiting one
by one, the extra processes, from the normal boot, in
activity monitor.Once you quit a process, allow the
computer to try to go to sleep i.e set energy saver
to 1minute and wait to see what happens.I tried the "
mdimport"as of Joeaux but this was not my problem.In
my case the sleep problem was down to two
applications called N67U_ButtonManager and
N124U_ButtonManager.These are for use with my Canon
scanner.I also noted that if i left the scanner
connected to the computer this would also stop it
going to sleep,even after deleting the two
applications.Hope this helps!
Thank you now i know that those login items are for my scanner, and not logic audio i am a little less angry(Logic is now an apple application but the version I run was from the emagic days and i presumed that the button managers were from this app as it was the oldest bit of software running on my machine) By the way any apps that may cause a problem like this are more than likely simply residing in your user login items and can be disabled from there permanently as far as i can see.

1st series iMac G5: Booting problems, kernel panics, waking from sleep...

Specifications of the iMac described: 1.8 Ghz, 1GB, 80GB, 64 Mb Nvidia VRAM, Airport, 10.5.5
Back in August 2004 my dad bought us kids an iMac G5 for ‘family use’. It had a fresh install of 10.3.5 on it and compared to the (1999) iMac G3 it replaced it was amazingly fast.
The iMac never showed any signs of probable issues, until we decided to upgrade to Leopard in January 2008. Initially, this upgrade was only meant to be able to sync with the latest iPod nano (who demanded a newer version of iTunes).
After the installation the first thing I noticed was a high CPU usage, the machine seemed slower than ever and that with 1 Gb of RAM (the minimum sys. req. for Leopard are 512 Mb of RAM). Anyway, then the real thing started, it wouldn’t turn on anymore. We brought it to an Authorized Apple Reseller, the Tech department said the Logic board had failed. The costs of the fix weren’t the worth the computer anymore, so...end of story. The iMac was indeed one of the bad series, although it hadn’t any swollen capacitors.
My dad already made up his mind and bought himself a Macbook. He then told me that if I was able to get the broken iMac fixed, I could keep it. And so, I bought an ‘as-is’ logic board on Ebay. Last weekend I installed it, and it actually seemed to work! Yet, the problems are during the startup: the first thing I see is a screen full with horizontal lines flickering all the time, like an old TV with bad signal. Mostly it won’t boot and I get the message to restart the computer (kernel panic, I got dozens of logs already!). Sometimes it got stuck during booting (grey apple screen with gear in the middle) making the fans go crazy (after a while) and sounding what others describe as a ‘jetliner taking off’ sound. Sometimes the screen remains black. Generally it takes me 5 to 10 minutes to start up properly. Maybe it’s just me but it seems like when the computer has warmed up a little (by turning on and off on and on) starting up gets smoother. I mean the startup screen suffers from less horizontal flickering lines.
During the use of Leopard, I again get high CPU usage, especially when I use multiple programs at the same time, or when starting multiple programs. My iStat Pro said once that the fans were running at 4700 rpm and the heat of the CPU was about 70 Celsius. If I really want to **** my iMac off I should play a racing game. That just totally freaks him out! These problems could probably be solved by adding more RAM. Right?
The iMac also has a sleep problem. Sometimes after lets say an hour or so, you can’t get it out of sleep mode (by manipulating keyboard and/or mouse, the sleep light stops, but the screen stays off --> only solution is to restart). What happened to me once was that it slept so long that it just got into a deep sleep by turning itself off completely!
Here’s a list of what I tried so far:
- Disk Utility: Resetting the permissions, no problems were found.
- Resetting the SMU, both on the logic board itself as by pressing the power button 5 - 8 seconds, no improvements.
- Resetting the PRAM, no improvements.
- Did the Hardware test of the original install CD, nothing was found, all good.
- Did Archive and Instal, this actually messed my system entirely, cause it wouldn't boot at all and when starting up from the Leopard installation DVD it wouldn't recognize the Macintosh HD.
- Did Archive and Instal with the original disks, this disk did recognize Macintosh HD and so I installed the original system, 10.3. Booting problems and those flickering lines are still there though.
Next phase will be erase and install, but first I want to know what you guys think about all this.
Oh eh, One more thing; The guys at Applecare (phone support) told me that the replaced logic board was also out of warranty and so they couldn’t help me. But as the man on the phone was kind, he told me to go look for a special ‘driver’ on the net. He said that the driver should be able to resolve some of the issues described. He said that I had to give in the name of the LB on google and look for results. Is this bogus? Because I haven’t found anything useful on google so far. What’s the name (rather than a number) of the LB in the first place?
I hope you guys can give me some answers. I'm kinda desperate. But I still feel there's hope...

The symptoms of a flakey power supply are sleep problems and you have done all the right things as far as resetting the SMU and PRAM. Your CPU usage can be tracked by going to Utilities>Activity Monitor - look and see what is hogging the memory. The flickering lines could also be an optical system going south.
The other thing you can do is run DiskWarrior or TechToolPro to see if you have corrupted directories. Preferential Treatment will let you check for corrupted preferences.

"Sleep" Problem iMac (Manual)

Commencing possibly two months ago I found that my usual procedure of manually sleeping my iMac (Apple | Sleep) at bedtime became erratic: Quite frequently (~75%) the iMac would instantly reawaken after about 1 or 2 seconds!
Discussing this problem with Apple Care, it was suggested that resetting the Power Management feature might solve the problem (shut down iMac, disconnect power, depress "on" switch 10 seconds, reconnect power).
This procedure seemed to correct the issue (but note that problem was never 100%). But it soon reappeared. I repeated the Power Management reset... and again it seemed to work. But... all was illusory!
Any "cures" known? I have a case number with Apple Care, but doubt they have anything new to suggest

If you select the option to preserve users and network preferences, an Archive and Install isn't such a problem.
However, my suggestion would be to Install on a freshly erased external hard drive using your original discs that came with the computer. Operate with that plain system long enough to determine if the problem no longer exists. I would then update that system to the last system version you used where you did not experience the wireless problem.
At this point you can then try an Archive and Install on your main drive then return to the working version using the appropriate Combo Updater. Just be sure to select the option to preserve users and network settings.
Beyond this I have no other options for you given you say you've tried everything else. You could take it to an Apple service center to determine if there is a valid hardware issue that can be fixed. Even marginal RAM could cause such a problem but would be difficult to track down because RAM tests may not reveal a problem.

Intermittent problem putting my 24" iMac to sleep.

About every tenth time I attempt to put my iMac to sleep it will do the following: The screen dims a bit, the cursor disappears and the clock stops. The machine then becomes totally unresponsive and all I can do is do a forced shutdown.
I thought it might have been the 'safe sleep' function so I disabled it. No change. I cleaned out all the caches, repaired permissions, checked the drive directory, reset the machine (pulling the cord, waiting and then putting back in and starting it up). Then I reset everything there is to reset! No change.
Has anyone had this happen? If so, have you found a solution?
Griff

Just to report a resolution to the problem putting my 24" iMac to sleep...
As I said, I put in two fresh 1G DIMMs (Shika brand). The two Kingston DIMMs were found to be defective. The sleep problem seems to be resolved. Also I found that a second problem (Applications suddenly and unexpectedly quitting) seems to have been resolved as well.
Something else I found as well is that the machine runs much faster. Right off the bat, when I ran the Apple Hardware Test, it was completed in 53 seconds. With my previous RAM it took over two minutes to complete.
Conclusion: Even if Utilities such as the Hardware Test and TechTool Pro 4 report no problem with RAM, some of the problems that people are experiencing that appear to be software based may be caused by bad RAM. It might be an idea to download and run Memtest or Rember over a period of a few hours to see if there is a problem. Or if you have access to a supply of RAM, you could swap in new ones and see if the problems go away.

IMac wake from sleep problem

I have an Intel imac that I've had for about 9 months. It is on a normal sleep setting and I usually wake it from sleep by moving the mouse.
In the past 3 weeks, though, I have had to wake it up by pressing the space bar. When I do this the computer pauses for a moment and I hear something wind down (I would say it is the hard drive, but the tone of the sound actually goes down rather than up - as if something got stuck on its way to sleeping).
Any ideas about this ? I also had the computer go to sleep yesterday and not wake up (led lights on screen were on, but nothing on the screen). I powered it down and tried to turn it back on, but same result (backlight on, but no boot up). I finally had to pull the power plug and restart the computer with the power button depressed. This seemed to shake up the computer and get it running again.
My sleep problem, though, is still the same. I'm not sure if these issues are related or not, but looking for some feedback on possible issues...
Thanks, Mark

Hi Mark
+The System Management Controller (SMC) is a chip on the logic board that controls all power functions for your computer. If your computer is experiencing any power issue, resetting the SMC may resolve it. The SMC controls several functions, including:+
+* Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth.+
+* Handling system resets from various commands.+
+* Controlling the fans.+
If you are still having any of the above issues reset the SMC as described in the following article!

Sleep problem with iMac Duo Core

I purchased this 20" iMac Duo Core five days ago. Whenever the iMac enter sleep mode with pulsating indicator light below the screen, waking up the iMac always cause complete reboot of iMac. Is this a known issue with 20" iMac Core Duo or there is some problems in configuration under System Preferences ? The SMC firmware was updated from version 1.1f2 to 1.1f5 for installing Windows XP through Boot Camp Assistant in a NTFS disk partition.

Thank you for the useful lead. The problem has been resolved by executing System Management Controller (SMC) reset procedure outlined in support site. Further monitoring on behaviour of the SMC is required. Hopefully this power management problem is not as big as with first generation iMac G5 I used to own. No idea whether latest SMC firmware update released by Apple resolve this problem though I have applied the update for Windows installation through Boot Camp.

Having problems putting iMac to sleep?

I've noticed lately that I have to click SLEEP two or three time to put my iMac into sleep mode. Is this the start of a bigger problem and what do I have to do to fix the problem. Any assistance will be appreciated.

See if something here helps http://support.apple.com/kb/HT1776?viewlocale=en_US
I'd also try resetting the SMC http://support.apple.com/kb/HT3964

IMac G5 pre-Intel sleep problem

I cannot put my iMac to sleep manually by using the toolbar. Have tried reinstalling OSX, and anything I can think of. Any help?

It could be the power supply, but it also could be a failing logic board or hard drive. If it were the power supply, your machine would shut off when it got too hot. If you can boot from your install disc, use Disk Utility to check your machine out:
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
You can also run Apple Hardware Test which should be on one of your install discs.
Once you done this, please let us know how things went,

UPS and our iMac // Will not allow iMac to sleep.

Hello,
We have a Cyberpower UPS (CP685AVR) for our 20" iMac 2.66Ghz (last gen)and it works great. It has a USB interface to communicate with the iMac's power manager, and tells me how much juice is left, how the cells are doing, etc.
The only problem is the UPS will not allow the iMac to sleep; if I try to manually put it to sleep, it will wake again in 10-15sec. If I disconnect the UPS, the iMac works just fine. There are no third-party drivers, either. Cyberpower relies on Apple's built-in UPS support. I've been leaving the USB cable unplugged but would like like to use it if possible.
Has anyone had an issue like this, and what has been your experience? Thanks.

I won't buy Cyberpower anymore since I had one burn up on me so I have not had any experience with their newer models. I have 2 APC's and they work fine with the built in Energy Saver settings.
Are you connecting the USB directly to the back? I'm not sure if it will help but you might try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US

Original iMac G5 Video Problem

I have not seen this particular problem yet - over the weekend I had my imac in sleep mode. I could not get the screen to come on. I forced the shut down by holding the power button in. Upon restart the computer appeared to start up but no display. I then reset the pram with no effect on the lack of video. I then unplugged the unit for a while and when replugging and starting there was again no video. What is interesting is when starting in safe mode the video will come on but you loose some of the capabilities. I then ran the hardware check and the video ram showed some errors. I can't seem to find why the video would work in safe mode and not in normal.
This is out of warranty and also out of apple care. I have an appointment to bring this in to a genius bar. Any thoughts on why the video would act this way.
Thanks for any responses
Bill Handy

After a trip to the Genius Bar it was determined that the video ram was starting to go. An attempt was made to reset the vram and after the next reboot the screen was still blank. Bottom line is this needs replacing and since it is part of the motherboard at a cost of $800. Looks like I will need to replace the imac.

Trouble when waking iMac from sleep?

When I wake my iMac from sleep I get an error message on screen telling me there has been an unexpected shutdown. Any clues as to the solution?

Thanks for the quick replies. When I look in System Diagnostic Reports there is nothing there, plenty in 'all messages. However I did copy the messages sent tp Apple on the last problem which I paste below...
