I got my first mac (13 in MBP) a few weeks ago & I'm not sure if the issue I'm having is hardware or software related. Pretty much the first day I got it I was setting it up, installing programs and such, and I went out to lunch and left it sit. When I got back, the screen wouldn't toggle back on. I'd seen it go in to sleep mode before, but I never let it sit for very long. I was out for a few hours this time & I ended up having to restart it to get the screen to come back up. After that I tested it a few times, shutting the lid and lifting it back up, and the first few times, it did the same thing. I pressed lightly on the frame where the lid and bottom meet and once the screen powered back up from that.
I ended up letting it go & taking it with me to class that night and since then I haven't experienced that issue to that extent. Rarely the screen won't toggle back on right away, but if I shut the lid and open it back up the screen comes back (usually with a two or three second delay).
What say you mac users, should I take it in to my local Apple store? I'm less inclined to now just because I have the whole thing set up & I really don't feel like having to do that for a third time (my first MBP had dead pixels). As long as I'm under my 1 year warranty I'm fine in case it does that again, right?
