can't turn on my fully loaded Meizu SL 8 GB

Would some please so kind an help me?
Yesterday I think my meizu had a hang-up.
I loaded the Meizu over night. But I am not able to turn the Meizu on, there is no reaction. If the Meizu is connected with my laptop, I have access to everything. But if I disconnect, I am not able to turn the Meizu on. Has anybody an idea, what I can do? With the manual I couldn't solve the problem. Thank you for your help!

If you do this:

firstly you have to turn your Meizu on, and after it can you have access to everything.

But try to hold enter button down for 30 seconds, after it, turn on.

Thank you very much. I pressed it for 45 seconds, then the Meizu turned on!

Next time I'll write a minute. I know, it's much time, but so much?!?!
