I think I may have found a solution for this. It's got to be an over-heating issue, because for the past 3 weeks I've charged mine overnight and it hasn't locked up...and before that it was freezing like every 5 nights. What I do is I take the battery cover off, open the keyboard, rest it on an angle and keep the screen on. It seems to be working so far! It just has to be overheating.
