My partner's goes to sleep instantly, mine takes about 30 seconds - most obvious difference is that I have MS Office installed (but not running).  I've tried resetting SMC but no benefit.  Help would be much appreciated.


MacBook Air (11-inch, Mid 2012), OS X Mountain Lion (10.8.1)

    any peripherals connected?

    No, nothing whatsoever.  Have just upgraded to the latest OS (10.8.2? Don't have the MacBook to hand, but was latest a few hours ago :-D), but hasn't helped.  Presumably some process is running that takes a while to close - but wary of closing down processes without knowing for sure what they're doing!

     

    In the *past* I had an external DVD drive attached - used it when installing MS Office - but hasn't been connected for months, and MacBook has been switched on and off and restarted several times since.

     

    Grateful for any help you can give!

     

    cheers,

    I agree that it's likely a piece of software that's taking longer to go idle. MS office has an auto-updater that causes this behavior. Printer software does too. I would be sure that it's third party software by booting the computer into Safe Mode. That entails holding down the Shift key as you boot the computer. You'll know you're doing it right when you see a progress bar under the Apple logo and spinning gear during boot, and the computer will stop at the login screen, and in red it will say Safe Boot. Then test.

     

    Other things to consider: Does it only happen when sleeping on the the timer, or does it also happen when putting the computer to sleep from the Apple menu? And does it happen in a new user?

    Thanks, logging in as "Guest" doesn't make any difference, even though MS Office isn't (apparently) running when logged in thereas.  From safe mode it enters sleep mode instantly when requested.  It's when putting to sleep on the Apple menu that I notice it - about a 30" lag between clicking the item and it actually going to sleep.  Haven't actually noticed it from the timer - indeed I'm not sure mine's ever inactive and on long enough for sleep timer to kick in - and of course it would be less noticeable under timer.

     

    Thanks again,

    ...additional news - since putting it in safe mode (whereupon it slept instantly on request) I've rebooted ordinarily, and wonder of wonders, it now sleeps quickly again!  Not sure what's happened but am not complaining - thanks for all your help.

     

    cheers,

    I was just getting ready to suggest booting into Safe Mode   Among other things, booting with Safe Mode deletes a number of cache files and it might have been a very large cache or a damaged cache that was causing the slow sleep. Keep Safe Mode in mind - it is a useful troubleshooting tool.

    Thanks, that makes sense - probably heresy here, but reminds me why I prefer Windows to Mac - much easier to find out/modify what's going on inside!  But again, many thanks - will remember for the future (and have to admit, the MacBook Air 11" is by far the most useful notebook when travelling!).

     

    cheers,

    Well, as a tech I'd agree that I have many more diagnostic tools to figure out what is going wrong with a Windows machine. But I need them. I have fewer software and configuration related issues with Macs than Windows. Plus it may be just a matter of familiarity.
