My sansa clip won't turn on...HELP!!!

I was recharging it on the computer and I unplugged it to check how much it was charged.  I turned it off so i can plug it in again to charge it but i plugged it into the computer before it fully turned off.   Now it won’t turn on and doesn’t re-act when I connect it to the computer.  The computer also doesn’t re-act to my sansa clip.  What should I do?

Nevermind, I just connected it to the computer (about 20 minutes later) and now it’s fine, but thanks to anyone who read this wanting to help.
