I have a mid 2012 MacBook Pro 13 inch. 10.8.4
Every so often when I open the lid to wake the MacBook from sleep (or without a lid on) it wakes momentarily, then the screen goes BLACK in like 2 or 3 seconds.
I have to wait for several seconds more and then i press a random button and the screen is resumed.. Any ideas on how to fix this? and do you think if it is a serious issue?
p.s.
i have read online that it might be caused by internet sharing but i am having it off
