iMac with Lion not waking after overnight sleep

Just to confirm this is not related to late 2009 iMac issue. There are posts of mac book pros and other models having this same issue. I have an Early 2009 iMac. It is very very weird. If you search my posts, I have posted a few times about my issue. In a nut shell, logitech blue tooth keyboard, apple magic mouse. IMac sometimes will not wake from sleep. I have to plug a USB keyboard and mouse in and restart the computer. This ONLY started happening after the lion upgrade. Doesn't matter whether you upgraded from app store or from DVD as there are posts of people confirming that. It's not related to just a track pad or magic mouse...it's deeper than that.

Someone even posted that they took the iMac back to the apple store. They replaced some hard ware, installed a fresh OS, and a week later he...or she still had the problem.

Wifi was always off on my iMac as my router is sitting on my desk. When my iMac would not wake from sleep, I would plug a usb keyboard in to troubleshoot. I would have no Internet connection and no blue tooth devices would respond yet Everything says its connected and working. BUT....

Today I tried my wifi. Computer went to sleep and would not wake up. I did the same steps to trouble shoot and for some reason , turning wifi off then back on, I was able to get on the Internet. This did not work with the Ethernet connection. This also did not work with bluetooth devices as I tried removing and re-adding and nothing.

Conclusion for me....I agree with previous tech services post. This is all related to the lion OS as I HAD NO ISSUES WITH SNOW LEOPARD. Whether it's the bluetooth stack or driver built into lion.....who knows. But it looks like No fix available till hopefully mountain lion upgrade.

Thanks for the glimmer of hope tech services. I hope the upgrade does fix it. I was seriously debating trading my iMac in for a newer 1 just because of this issue......even though there is absolutely nothing wrong with my iMac.

😕😕😕

Hi.

I too thought about upgrading my iMac to get around his annoying issue.

Reckon I can wait on the retina iMacs to appear first - no rush...

Still going strong here and I sleep/wake up a lot of times in 24 hrs!!

Mountain Lion seems to be the answer !

I've never enjoyed this level of reliability with my Magic Trackpad and mouse since Ohhh since snow leopard !!!!!

:-)

All,

Just to confirm, since I installed Mountain Lion GM, this problem went away! I didn't see it since. Good progress. If they would not fix this for Lion, people who bought Lion (like me) might feel cheated.

Hi.

I am now happy to say that Mountain Lion GM has fixed this problem for me totally.

I have been testing this since the GM Seed came out now and it has awoken from sleep countless times with no problem whatsoever with mouse, internet, usb or trackpad - unheard of before with Lion (although not Snow Leopard).

Hopefully Apple can regress a patch to sort Lion but if not the upgrade is well worth it anyway.

I felt the wake up tonight was a particularly hard one - with parallels suspended in the backgroudn etc - not one issue...

Look forward to more reports from others - thats great to hear guido4096 report also.

Only a few more "sleeps" to having this fixed!

I have Lion installed on my Late 2009 iMac. OFTEN and getting worse, the Mac won't wake up after sleep unless I touch the back power button and then the screen comes on but the BT Trackpad and Keyboard don't work resulting in a necessary hard shut down. Hate this. Remiins me of an old computer getting sick and for $2900 I'm not thrilled. Still have Applecare will give them a call. Not confident they'll be of help.

Mountain Lion appears to have fixed this problem. A bit early I know to make this claim but the wake-up behaviour is very solid whereas before it was always flaky even if the system hadn't actually hung.

Mountain Lion has definately fixed the problem for me - no issues on my system at all since installing the GM seed on 10th July. Thats 20 solid days now of testing this - never got anything remotely near that before.

Well....the jury is still out on this one. I upgraded to mountain lion the day it launched and just as Tech World and Gratullin, the "won't wake from sleep " bluetooth problem seemed to go away. But after about 3 days, while using my imac, it froze.....or so I thought. All Bluetooth connections just dropped. First the magic mouse stopped responding, then the keyboard. (logitech dinovo mac edition Bluetooth keyboard). Then I tried plugging in a usb keyboard (which always worked in the past when the "sleep issue" would occur). But usb was keyboard or mouse was also not responding.😠😠

My e-mail was still on the screen and I noticed new emails coming in so I knew wifi and machine was still somewhat working. So...... What to do?

This was the first time ever since I purchased my imac (purchased new early 2009) that I had to hard power down. (holding the power button until the mac shut down). And of course my apple care ran a few months ago.

Its been a few days since this occurred and I've been unable to duplicate the issue so......the jury is still out for me. 😕😕😕

I've had to hard shut down at least 10-12 times on my Late 2009 iMac. I'm going to wait a while on Mountain Lion.

Hi there, I suggest you do a permission fix, after a reboot. Even better is you do it via the recovery disk, but doing it after a normal reset is also fine.

That's what I had to do after my ML upg, and since I have a great uptime and no such issues as in

on my late 2009 iMac.

@Techworld Services

Great to hear that, I'm also happy with ML my self.

Hope the system doesn't p00p its self. :-)

Hi,

the problem is the Bluetooth Daemon (blued).

If You restart the daemon (via ssh, remote connection or with the USB-keyboard), all bluetooth devices are reconnected.

Or do like I did.

-open terminal

-type: "sudo -i"

-type: "crontab -e"

-press "ESC" + "i" (edit mode)

-type: "5 * * * * blued"

-press "ESC" + "s" and "ENTER" to save crontab

-type: "exit" to exit from terminal

After that, Your OS X will restart bluetooth daemon every five minutes and if the bluetooth daemon crashes and You lost keyboard, trackpad and mouse, just wait until bluetoot daemon restarts within 5 minutes.

I did not have any problems with Lion and I have not had any problems with Mountain Lion either. I installed both as a full version. I have run both on a 27 inches Mac computer

@Kristian_F

Been there, done that.

May help some folks, but not in all cases.

All I can say is, ML + permission fix did seems to have done the trick.

So far, at least. :-)
