MBA 13 (new model 2011) heats up rapidly after wake up from sleep

Hi! I bought the MBA in August and I have installed all the firmware and software updates. After installing the EFI 2.1. in September I have the following issue. When opening the lid of the MBA after several hours of sleep, the CPU temp rises very fast without doing anything on the MBA (no Internet, no wordprocessinh, no nothing). I have Temperature monitor installed and after 4-5 minures CPU gets 70-80 Celsius with fan working very loud. When I close the lid for 3-4 second and then open it again the CPU temperatures gets normal - between 40-45 degrees. With Internet it is around 50 degrees - no fan, absolutely calm.


I have made two Lion installs yesterday - one a clean install (erasing HDD), and one with preserving programs and data. No result, same behavior. I suspect that it has something to do with the deep state sleep in hybernate status. And I suspect it is problem with EFI 2.1., because prior to this the MBA reacted normally after wake up frim sleep. I goodled around, checked English and German forum, but not a hint or solution.


I can get accustomed to this second opening of the lid, but I don't think it's normal. By the way, when I shut down the MBA and start up after a night or so, there is no such behavior. Only after wake up after many hours of sleep.


Any ideas or solutions?

I am seeing exactly the same symptoms but the trigger seems to be different. For example this morning my MBA (i7, 1.8) was doing a lengthy Time Machine backup and the fan started to run fast. When the backup ended, the fan kept on running fast and the temperature stayed high. Something was still clearly generating heat but virtually no CPU activity reported in Activity Monitor. I"m no expert but I guess that does point to an EFI issue...?

I just want to let you guys know that I received a replacement from Apple a couple of weeks ago. A MBA 2014 i7.


I had a 2011 Macbook Air i7 11". Under only one month the motherboard was replaced, the SSD was replaced, the I/O board was replaced, the heatsink and fan was replaced, even the trackpad... nothing solved the issue.


It was hard to replicate the problem, more than a month repairing, bringing in and out of the workshop, only a couple of times the techs were able to do it. At home I replicated the problem every time nevertheless. It was rather annoying, about 7 times in a month I had to go this small Apple workshop.


The issue wasn't hardware related, it has to do with the OS and some of its EFI updates. The charger has nothing to do with it, I even had a brand new one.


I had Apple Care and was about to expire, made some phone calls to Apple, someone took care of my case, I had to kindly explain that it was not the hardware, rather OS related. A couple of days had gone by, heard nothing from Apple, made a phone call again explainig the frustrating experience and that no matter what they replaced, the issue was there.


That solution about disconnecting the power adapter, waking up the computer and plugging it in a couple of minutes later or shutting off Safesleep isn't really acceptable if you paid that much money. That kind of "BETA" testers' work can go to Apple and it's their thing if they want to find out about bugs and how to bypass them, etc etc. It isn't "us" as users that pay a rather high price for a laptop who should resolve this.


Stand up for your rights, push and make a claim for something that works.


Good luck!

I know this is an old thread, but it appears to be the best one concerning the hot battery issue. I disabled TimeCapsule at once because of the memory it was using. The battery issue has not annoyed me until now. Each time I play a certain game on my MBA 2011 i7 1.8 I have to close the lid because of the heat. Are you saying, Chewbaccair, that your MBA 2011 was replaced with a 2014 model?
