Macbook Pro Retina runs hot while lid is closed and fans working at full speed

After a few weeks of no problem with the laptop running hot when supposed to be in sleep mode, I just got bit by this again. I found what looks like an obvious cause, which was iMovie was processing some movie clips I imported and was porcessing, but closing the lid should suspend this or warn me. Failure to do this this and with no other obvious visual indication that the machine is actually running, processing and generating heat is going to be deadly since my pretty machine will be going into a bag after I close the lid.

Please, please Apple pay attention to this problem. I do not want to melt my MBPr.

Hi, sorry to jump in late, but is there a fix for this?

I've had my MBPr for about a month now and I've had this happen twice. Very frustrating.

This happened to me first time last week. Closed lid, returned about an hour later to find fan going crazy and machine very hot to touch. When I opened the lid the screen was black and machine unresponsive. Only option was to hold down power button. Machine then booted as normal. All latest Apple updates had been applied before this occurred.

I took the machine to the Apple Store yesterday. They did the following:

* Ran diagnostics - no issues found

* Searched logs - nothing unusual

* Reset SMC

Outcome:

* Symptoms hint at issue with Power Nap. But not rule out machine not going to sleep properly.

* Asked to keep note of when machine is put to sleep.

* Given reassurance that if occurred again when charging machine would eventually reach max allowed temperature and turn/cut off.

* If happens again to return the machine for further, more extensive checks

After few test at the AS they are going to change it.

Just took my 10.8.2 retina MBP out of a bag to find it toasting hot with fans running at full speed. Opened the lid and the screen was black and did not come on from tapping keys. I let the fans carry on to cool it and then did a force reboot once they had slowed. Started up fine thankfully - but clearly a bad thing to have a computer stressing it's components in this way - and should not be able to happen. I think it had been put to sleep from the menu before shutting the lid.

I have just now turned off 'Wake for Wi-Fi network access' along with 'Enable Power Nap' in the hope that this may help avoid repetition of the issue.

The fist message in the console which looks suspect and is at the time I guess it woke is:

19/10/2012 22:20:22.000 kernel[0]: Wake reason: EC.DarkPME (Maintenance)

Anyone know what this means?

The next few lines are:

19/10/2012 22:20:22.000 kernel[0]: AirPort_Brcm43xx::powerChange: System Wake - Full Wake/ Dark Wake / Maintenance wake

19/10/2012 22:20:22.000 kernel[0]: AirPort_Brcm43xx::checkInterfacePowerState: Check _pwrOffThreadCall!

19/10/2012 22:20:22.000 kernel[0]: RTC: PowerByCalendarDate setting ignored

19/10/2012 22:20:22.000 kernel[0]: Previous Sleep Cause: 5

Seems like this thread is long enough to suggest that there should be a software update to prevent a computer from waking if the lid is shut!

I will add my problem to this thread. MPBR runs super hot when plugged in and lid closed. I often find, when I reopen it, that it has rebooted while closed.

Apple, please fix.

Posting again after a weird event. I was sitting at home with my MBPr on my coffee table, lid closed so theoretically in sleep mode when all of a sudden the fans come on full and run for a couple of minutes, until eventually they slow down and the machine gets quiet. I pop open the lid and check things out. It has just restarted and OSX is saying an error has occured and the machine restarted. Bizarre. So going back and thinking thru my own history of opening up my bag to find my poor machine cooking away, maybe this is what's going on. You pop the laptop into your bag in sleep mode and something crashes, even though it should be sleeping, aand the machine restarts.

Wishing Apple would figure out what's going on here.

Same here with MBPr running 10.8.2. fan running without reason when lid closed, and even after put it into observation (deep sleep) using Deepsleep. Fan will still start itself after a couple of minutes with lid close

Fix this lousy bug please Apple. This is the prolem with soft key to turn off and on the machine. Never happen before with MacBook Pro hat have hard mechanical on/off key

This happened to me as well. 13" Retina Macbook Pro purchased mid-October running OSX version 10.8.1. Run it normally in clamshell mode connected to a Thunderbolt display. Disconnected power and display cables. Put the computer into my carrying bag (cushion also acts as insulator). Went to concert and then home. Computer was in bag for about 5-6 hours. Heard noise coming from bag. Reached in and computer was almost too hot to touch with fans blazing. Pulled it out of bag and made video of fans on turbo. Took it to Mac store and they tried to run diagnostics. Diagnostics hung so they gave me a new one. Satisfactory from customer service perspective but I don't want to have to do this every month or so. Seems like it would be in Apple's interest to fix this to avoid having to give away a bunch of hardware replacements.

...where is "wake for network access" in System Preference?

Hi there

I'm in desperate need of upgrading my system and was thinking of a new 27-inch iMac, keeping my old 17-inch MBP for presenatations only. However, with the new iMacs still yet to be released, potential production issues with the new-design and the general reluctance to be an early adopter ...I've been checking out alternative strategies.

I have decided to invest in a 15-inch MacBook Pro with Retina Display (fully loaded) and have this power two third-party 24-inch displays, such that the MBPr would operate with the lid closed.

I understand that most of what's been discussed so far concerns putting the machine to sleep, particularly before storing it in a bag during transit. I'm wondering whether anyone has had heat issues with running a MBPr in the kind of set-up I'm suggesting?

This happened to me this morning. I closed the lid of my rMBP then placed inside the macbook case, and then into my rucksack alongside an iPad with Smartcover. I checked my rucksack at lunchtime and my bag was really warm.. I checked the macbook and it was scorching hot with fans on full blast.

This is the first time it has happened.. and the only time I've closed the lid and placed alongside an iPad with Smartcover...

I'll do some tests this evening with and without a Smartcover in proximity..

I tested with a smartcover in proximity of the macbook on sleep and this didn't affect it. I guess that rules out the smartcover theory..
