I am experiencing strange issue with my MacBook Air (2011, with Mavericks):

  • I don't like to turn off my machine, so I usually just close the lid and put my laptop to backpack before I go to sleep
  • I take it off the bag in the morning at the work, do only basic work (email etc. - no suspicious things in Activity Monitor), but my MacBook Air will get to high temperatures (90℃ for CPU, runs fan at 6000 RPM).

I can 'solve' that by putting computer to sleep, wait a while (~30 sec), wake it up again and temperatures will get back to normal. I already tried resetting the SCM.

Notes:

  • I don't keep MagSafe connected to my Macbook Air during the night
  • I usually have plenty of running apps on my laptop (4GB of RAM, but Virtual Memory usually tops 10 GB)
  • I always run 1 instance of CentOS in VirtualBox (with Oracle database)
  • The VM would be the first place I'd check. What happens if you pause it before sleeping? If you save state and close? – zigg Jan 21 '14 at 14:41
  • I will try tonight and update this post. – Xorty Jan 21 '14 at 15:26
  • Unfortunatelly I was able to reproduce the same problem even with paused VM. Any other suggestions will be appreciated. – Xorty Jan 22 '14 at 9:12
  • I tried disabling deep sleep and see if that helps: pocketpccentral.net/blog/2011/08/02/disable-safe-sleep-lion – Xorty Jan 23 '14 at 9:12

Disabling the deep sleep seemed to have fixed the issue for me.
