Repost: Fix MacBook Air Sleep Problem

I’ve posted previously about problems that I’ve had with my MacBook Air 13” (2011 edition). 

An additional one that crept up was its maddeningly random inability to wake from sleep.  I typically take it to a client site everyday (or elsewhere when I’m travelling) and put it to sleep for the commute each way, and on too many numerous occasions, it failed to wake up, requiring a full power cycle, and then hope I remembered to save everything before it slept.

This post details a fix that, after a week or so, appears to have resolved the issue.  You have to go into System Preferences and select a startup disk.

Why does this work?  I don’t know, and neither does the original poster, but it appears to work, at least for some.
