Why does my computer "reboot" after sleeping?

[Ricky.Flores]

I have a MacBook Pro ( mid-2012) and I was wondering why does my computer do this when I open it. It has been doing this for awhile but not always. I would hate it if it is an internal problem and I don't want to go to an Apple store.

What happens is that when I open my laptop, it "boots" up and becomes laggy until about 15 seconds. How do I get rid of the booting?

If this thread is already circulating through the forum, I do apologize. It is not easy to describe something that you don't know.

That is restoring from hibernate. Happens when your battery gets low or if you have force-enabled it to do so all the time.

Yeah that happens when your battery was / is almost dead.
