Different Boot sequence on diferente MPC Live Units

When my friend boots his MPC it says "make good music"(or a similar sentence) with the START button at the center of the screen you should press to acces to the demo, templates and recent project Window.

In my case the START button with the "let's make some beats" text is not present

Does everybody has that windows saying that text?

you can see the sequence im talking about in this video at 2:20.

and in this other video at 3:40 you can check in some cases it does not appear.

Why is this?

Because its Plugged in. If Im not mistaken, The Start button appears when its on Battery Power

That's right!

How did you notice that's the reason?

Thank's a lot!

Lol Because I have a MPC LIve. I noticed it because I don't like to keep the Live Plugged up all the time. It Kills the Battery over time. And everytime its plugged up, it goes right into it. A safety feature in case the Power Button is engaged while in a bag or somethin
