My music isn't returning back to life!

I was in my school library listening to my Sansa Clip+ like I usually do, typing a paper. I was listening to my song and it had suddent shut off! I charged it completely Saturday night. Didn’t use it, or touch it. I only use my music when I am at school and all of a sudden, it died? What’s wrong?

I plugged it into my laptop when I got back from school and it’s not flashing, or returning back to life! Oh my gosh! Can it possibly die out that fast? I haven’t even had it for a year! Did it die? It’s full charged. Do I have to get a new music player? D:

HELP MEEEEEEEEEEEEEE!

Relax . . . just reset it.

How do I do that?
