I have an early 2011 MBP running Mountain Lion.
Most of the time when I shut the lid of my laptop, and then reopen it , everything works fine.
However on an increasing number of occasions, when I re open my MBP, all I see is a black screen, which takes anything from 10 seconds to 5 minutes to come to life.
Why is this happening and what can I do about it, I can live with the 10 seconds, but 5 minutes is just too long.
