My switch displays the logo on a black background and won't respond to input. How do I fix this?

The other day, I pulled the switch from its dock, and it had the logo on it. I said "Oh, its probably just resetting itsellf." Twenty minutes later, I look at it again. It hasn't changed. I start to get worried. Can any one find out how to fix this? I would be very grateful.

do a hard reset. Hold down the power button until it turns off then continue to hold it down for another 30sec. then turn it back on.
