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

I'm not running Chrome. I have it installed, but I'm not running it. I have Mail, Calendar, Address book, Firefox running and that's it. I did have Fusion running the first time it happened, but I've terminated it... and am still seeing the problem.

When closing the lid of your notebook, always make sure the light starts pulsing before leaving it. If it doesn't, try to determine what is keeping it from sleeping. If you don't have time for diagnostics, just power it off.

What light? There does not appear to be a light on the MacBook with retina. (My old MacBook has a light). Is there a light I may not be aware of?

The problem appears to be something associated with xcode. I'm noticing that I have some misc problems with system hangs when I use xcode and exit out of it. It maybe coincidental but there is some sort of correlation.

Apparently not. Since it has an SSD and Lion can autoresume (almost) everything, I say you should shutdown any notebook without a sleep indicator light before storing it for more than a couple of minutes. It isn't common for sleep to fail, but it happens enough for me to worry about.

I'm sorry, but after spending $3K for a laptop I should be able to expect it to do at least the same thing as a $1200 model. I'm not willing to shut down everytime I store it. I'll get a PC if I need to that!

Then you're in luck. Because a dead MacBook Pro Retina probably has at least as much value as a working PC. Just close it and hope for the best. If it melts the screen, you can sell the parts on eBay. Personally, I suggest AppleCare. If there is no sleep indicator light then Apple is assuming responsibility for successful sleep. If it doesn't sleep and melts, Apple should fix it.

Most/all laptops have temperature sensors that would shut the system down way before it "melts". Do you have any idea how hot it would need to get to melt glass?? Apple already takes responsibility... and there is no light on McBook Air as well.

Thanks for your help, but I really don't need advice on how to live with this problem... I'm looking for a solution.

It is called hyperbole. What is more likely is that your fans will run fast enough to get your machine airborne if it weren't in your backpack. (Another funny example of hyperbole for those of you keeping score at home). Then, when you arrive at your destination, you will have to work tethered to your brick just like all the PC losers.

It is rare for a Mac not to sleep when the lid is closed, but it does happen. Apple even used to recommend the same thing: http://support.apple.com/kb/TA25026 I think that is good advice even with SSD drives. If you don't have a light but do have an SSD and Lion, I think a shutdown is a safe, convenient alternative.

If you read the article, it is focused on the safety of the HDD. The entire reason why Apple put the light on their laptops was to inform the user as to when the HDD was cycled down, so you know when it safe to move the laptop. Once there was no HHD... there was no light. That's why there is no light on the MacBook Air and MacBook Pro Retina...

MBPR's don't have the pulsing light. Make sure it's securely closed and the apple light goes out. Also make sure there's no way it can open *after* it's in your backpack or case. That happened on my old MBP because the hinge was a little loose and it flopped open on its own.

Yes.... This past week, it happened once again. I've deleted Chrome. I suspected it has something to do with xcode, but it now does not seem related. Is anyone else still seeing the problem?
