I can't get my Leappad 2 to come on.

My Leapfrog Leappad 2 32610 will not power on. With batteries in, or plugged into the wall with the power cord. What could be wrong with it. Maybe the on/off switch is broken? I was given this device by a friend that said it worked, but needed batteries. New batteries, and plugged in to wall with power cord, and it still does not come on. Suggestions?
