Apple Event: May 7th at 7 am PT
I used to be able to close the lid with whatever was running when i went to bed at night and wake up and lose 3-5%. Now when i wake up the computer has lost 40-50% if not more. I have tried the following.
1. reset SMC
2. reset energy preferences
3. change pmset hibernation type.
Any help would be greatly appreciated.
MacBook Air, OS X Mavericks (10.9.2), 2013 Model
I went ahead and bit the bullet - a virgin install of 10.9.3. No joy. Same battery burn problem if you forget to quiet Windows. This is a very unpeasant situation.
The trouble is that it isn't just Parallels and Windows 8. For me, I suspect that it is VMWare Fusion and Ubuntu.
It appears that Apple messed up power management for virtual machines in 10.9.2
Question to any Apple person who reads this -- does Apple recognize that this is problem? If not, then what process should we follow to make it clear that this is a problem?
This problem occured on my Macbook Air 13 Mid 2013 right after the upgrade from 10.9.1 to 10.9.2
Before i never experienced this problem. Now with 10.9.3 its still the same problem.
Just today i came back from work and the MacBook Air was running hot in my bag with full speed fans.
It was extremely hot to touch. This will reduce the life of my battery and hardware in no time.
The only workaround for this is to shutdown the Macbook completely, which costs me a lot of time for shutdown
and startup evertime during work breaks or while i am on the road.
I follow this support thread since 2 months and the problem exists since 3 months!
Apple Company never commented about this problem and never tried to help the customer!
What a lousy and unprofessional support is that from Apple?
I paid over 2500 USD for this notebook and they can't provide a fix for this problem within 3 months?
I exspect they release a fix for this problem immediately.
I'm working in a large IT company and it is unbelieveble to me, that they not even raise a bug information
or reply in this message thread.
Usually, if many customer experience the same problem and report it, a bug track should be started and the troubled customers should be informed about the bug fix progress.
I was also at the Genius Bar in the Apple Shop and they didnt know about this problem and were unable to help, other than replase the MacBook because they think it's hardware related.
If they not release a fix within 2 weeks, i will return the notebook and ask for a full refund and i would suggest
everyone bring back their MacBook Air until they fix this serious problem.
Well, help MAY have arrived! I installed the MacBook Air SMC Firmware Update (App Store) this morning and after a 45 minute "I just have to see if this works" sleep test, the machine awoke with 100% battery left. A miracle?
Since I upgraded to 10.9.3, things have been much better. However, I also had to reset my PRAM twice as the display on my MBP stops working. One of these two things seems to have helped.
By the way, resetting the PRAM seems harmless and is easy to do (http://support.apple.com/kb/ph14222) and it might help.

I figured I would loop back to report that the problem still exists. It seems more intermittent but is unmistakably present most times I snap the MBA closed with something "active" like MS Outlook still open. It's worth noting this same process works flawlessly before 10.9.2.
I am on a new track now since I recently opened my bag to find the MBA cooking-hot and the display malfunctioning. Sending the unit in under AppleCare and pressing for a replacement. Will advise.
Has ANYONE found light in this tunnel (MBA plus 10.9.3 plus Parallels plus Windows) or are we all just dancing around the problem by closing programs before sleeping?
Mavericks 10.9.2. drains my 2013 MBA's battery incredibly fast while sleeping.
