When i open the lid and check the activity monitor a different process runs at 100% everytime. After I open the lid the process goes back to normal, the mbp cools down and fans slow down. It only started happening after few days of use.
Any suggestions would be greatly appreciated!
Thanks!
MacBook Pro with Retina display
If I remember correctly, in my case the problem was an external monitor that I connected to the HDMI port. The monitor used to work fine with a Windows laptop, but if I kept it in the MacBook while it was sleeping (the monitor was sleeping too), it caused the Mac to overheat. When I disconnected the monitor, the problem disappeared.
Wow.... it's happening with Mountain Lion as well. Has anyone taken it into to the store or called Apple about it? I've just been on the forums and assumed they had. What was the 'official' word on this problem?
I'm just weighing in on this thread to provide another datapoint.
I'm running my MBPR with an up-to-date Lion (no ML) and I have never experienced the "won't sleep" issue. I don't use any of the applications (Spotify) that might trigger an "always on" state. I also do not access this MBPR from remote computers (i.e., no wake-on-lan triggers).
I do put it to sleep at least once or twice a day by simply closing the lid and it goes to sleep every time.
For the people who might have recently joined this thread, there was an early post that mentioned a command that would list running apps that might be keeping your MBP from sleeping (like spotify). Are you really sure it's not a software issue?
I'm not using spotify... I'm using mail, address book, firefox and skype. Which of these has the capability of triggering always on?
BTW... when I close the lid when it's out on my desk.... this problem does not seem to occur. It's seems to be happening occasionally when I put it in my backpack.
The interesting thing is that this occurs also when i put the mbp in the backpack and not when i close it on the table. Maybe it opens a little somehow in there or something about keeping it vertical position. Can other people in thread that had that issue confirm if they had it when the mbp was on the table or in some kind of a bag. Maybe thats the common link.
I totally agree!
I have seen video of this issue on youtube showing that it was on a table. I'm not sure if it was in a bag previous to the video starting.
I've been following this before I got mine MBPR. Well Since then I've never close the lid and put it in my bag. I always shutdown with reopen and it's madly fast.
Don't give it a chance again do the shutdown instead of sleep till they say something about it.
Good luck
Yep. Just out from the bag and noticed the fans were running (and it was really really hot). For shooting I had to lay it down.
I always thought that when the system was out on the desk, it had enough ventilation, so you couldn't tell that was running. When you put in the backpack, it doesn't have ventilation and thus got warm. I don't have anything to back this up, as it is based on assumption. I do notice that when I put to sleep before closing the lid and packing it, it's always way cooler than when I don't.
IT'S FIXED!!!! THE FIRMWARE UPDATE SAYS IT FIXES A SLEEP/WAKE ISSUE AND ENABLES POWERNAP!!!!
Are you sure? We need to have a few people on this thread try that for their problem and let us know if it's the answer.
Just updated. Le'ts see...
Sorry to say that is NOT fixed. My MBP Retina has been updated to Mountain Lion and I've updated the firmware as well. Well, today, I closed the lid, without switching it off and put it into his second skin. After few minutes I heard the fan running like ****. I took it out and it was really hot. How is it possible????? It seems like it hates the second skin.
I just experienced the same problem.
Put my MBPr to sleep at about 5:30pm, and just went to go to bed now and could hear the fans going while the MBPr is in my bag. It's 10:30pm and when i opened it up it was at 30% battery left (from 100% when i put it to sleep). It was very hot and could not put it on my lap. hopefully the heat has not damaged anything or harmed the battery.
Opening Activity Monitor kernel_task was running at 580%+ CPU usage.
WiFi is off.
Power Nap while on Battery Power is also off.
I do not have Xcode installed, or any Virtualisation software running.
Looking at the system logs, there is activity between when i put it to sleep at 530pm and when i just opened it now. A lot of Calendar refresh attemps.
How ever looking specificaly at kernel flagged logs, there is errors related to Thunderbolt Ethernet. i use the TB Ethernet adapter while using the laptop today, but disconnected it when i put it to sleep at 530pm..
Because there was 30% battery life when i opened it at 1030pm, that suggests it the fans have only been running full tilt for maybe an hour or so.
Anyway, i hope Apple are looking into this and in the mean time i will shut down my MBPr when transporting it.
EDIT: i'm running 10.8 with all updates applied at time of writing this. MBPr 15" 2.7GHz 16GB/768GB
Awesome details thanks man. It was so helpful.
WiFi was off and there was no Ethernet cable connected. So there was no Internet why Calendar had so many refresh attempts and from where?
Anyway, thank you so much it was perfect.
