27" iMac won't wake from sleep (sometimes)

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?

Please help!

I am experiencing the same problem on my 2010 i7 iMac. About once a week I must unplug to restart. This just started about 4 weeks ago. I cannot figure out why this is occurring. I guess I will call tech support at apple as it is still under warranty. If I find a resolve I will post.

Add me to the list of people experiencing this problem. Started maybe a couple weeks ago, and only happens once every 5-7 days. Programs I typically leave running include:

iCal, Outlook 2011, Word 2011, Excel 2011, Adobe Illustrator, Adobe InDesign, Adobe Photoshop, iTunes, FontExplorer X Pro, perhaps Safari, Growl's HelperApp...

I'll update that list if I think of anything else. Not sure what is causing it. My coworkers usually have most of those programs running, too, but don't have an issue. I am probably the only one of us who uses iCal and Growl, though.


Early 2010 iMac 2.8GHz i7 running 10.6.5.

Happens to me too

It has to be something with the recent updates to Bootcamp. This issue started for me about five weeks ago. What a pain. My machine is 27" 2008 variety.

I had my imac for a week or two before it started doing it as well. I really want to believe it has to do with an update, b/c it was fine for a period of time, then the problem seems to have started after updates. Did a hardware reset, seemed to work for a couple days, but then today, sure enough, back to the problem. Appreciate the feedback though.

Hmmm. Well looks like I'm not the only one. Hopefully someone can find an answer.

Same Issue

I have the same issue with my relatively new 27" iMac and I never turn it off or reboot until this happens. I'm under Apple Care so will also open a ticket.

It happens to me every once in a while (say 1 within a week).

At the moment I only leave the following programs in memory, Safari, Firefox, Chrome, Parrallels (occasionally) and VLC. I do not think it is bluetooth related because I have a usb keyboard plugged in.

I've decided to start recording the times and Mac OS X logs visa /Applications/Utilities/Console.app to see if I can find a pattern.

Hopefully I'll be able to post some results within a few weeks.

Mine does this as well. It is only about two months old.

The iMac will be completely non-responsive. Hitting the power button will not turn it on, holding the power button will not force it to boot... the only thing that seems to work is tapping the power button a few times in a row.

I usually have a few app running. I have iTunes set to always be open (to feed content to the Apple TV), Suitcase Fusion 3 is always running. I use the wireless bluetooth keyboard and magic mouse. The machine also has a 2TB WD drive hooked to it via USB.

FYI - When it happens, you can hard reboot the machine by holding the power button for 5 seconds...release and then tap again. I called AppleCare about the issue and they had me reset the PRAM and re-pair all bluetooth devices. It worked for a week or so, but the problem has happened to me twice since.

I'm worried it could be a bigger issue with the machine itself. The last thing I want is some Genius ripping my baby open and replacing parts 6 months after I got it...Hoping the issue fixes itself when Lion comes out I guess

I just had the problem yesterday with my brand new i5 machine. I had to hold the power button for 5 seconds and restart. I've had this machine about a week now. First and only time. I have a i3 21.5inch iMac as well and have yet to encounter this. I've had that machine almost six months without issue.

How do you do this??

I have this same problem with my i3 21.5 I bought in September. If the machine sleeps for more than 24hrs, it doesnt wake up. Lazy machine. Its really getting annoying now though...I think I will call AppleCare tonight.

I'm pretty sure this has something to do with your keyboard and mouse losing connection during sleep. This seems to be the problem with mine when I have been unable to wake the computer.

A clear sign that it's your keyboard (on mine atleast), is that the CAPS light doe's not work (or stays on all the time) for some unknown reason.

If it is this, then the only solution is to restart your mac.

Go into Disk Utility and Repair Disk Permissions. As the guy above said, the CAPS LOCK light not working is a dead giveaway that there's some error in the bluetooth connection that needs to be fixed with a restart.

Again...since I repaired disk permissions and reset PRAM I have not had an issue.

Hmmmm...never noticed the CAPS light, great suggestion. Silly question, what do I need to do in order to repair permissions? Is this as simple as clicking 'OK' or is their more involved?

I reset the SMC lastnight as per Apple. However, now it seems that the iMac never wants to sleep. My screen saver comes on, does its thing, then screen goes black and about a minute later the desktop pops up again. If it keeps this up, I won't have to worry about the disconnecting bluetooth!

In Disk Utility, click on your Macintosh HD disk and then on the First Aid tab. There should be a button that says Repair Disk Permissions click that and say yes to anything that pops up. You should see the repairs that are made in the details window. Once done...restart your Mac and you should be good.

Problem is back. Called AppleCare again and they were a bit stumped. They wanted me to reboot in safe mode and delete the keyboard from the bluetooth list, but we couldn't because I don't have a wired keyboard to communicate with the iMac after deleting the bluetooth keyboard.

Their other option was to bring it to the Apple Store and leave it with them for diagnostic testing. No way I'm lugging this thing through the mall and since many others are having this problem, it would probably be a waist of time.

Now I'm just hoping a clean install of Lion will fix this if it is a software bug.

Identified the Won't Wake from Sleep Issue

Hi,

I identified the will not wake from sleep issue due to Bluetooth.

The way I solved it, got rid of my bluetooth mouse and keyboard and switched to USB. It was getting annoying playing StarCraft 2 anyway with Bluetooth. Since Feb 20, 2011 after switching to USB I have never had the sleep issue.

Now the USB solution may not work for you if you are stuck on Bluetooth. Here are two more options I can see.

1) Try and move your Bluetooth mouse and keyboard closer to the iMac. Based on what I can see in the system logs, at some point Mac OS X loses the connection and puts itself in a loop and then get's stuck there.

2) Call Apple with this data and ask them to replicate this issue and fix Mac OS X so this stops happening. There is not special software that interferes with this. Nor is due to how things are setup. I verified this by wiping and re-installing Mac OS X with updates 10.6.4 - 10.6.7 multiple times different ways without additional software and duplicated this issue. Apple should be able to duplicate this issue themselves with this info.

I still have a ticket open and will try to get around to calling them. We just had a baby so there are other priories right now so don't hold your breath.

Below are the tail end of my logs with some of my notes during the process marked with *** (all my logs would be too long for this post).

Admittedly, I did not organize everything, I went through many many logs not shown here, but hopefully this will help others googling and those interested in pursuing further with Apple.
