I would say this is NOT normal. Shouldn't be happening.
Certainly implies it is not really "sleeping", but instead actually running something (other than the clock). If the screen goes black when you enter sleep mode, it shouldn't be the screen that is draining power.
I would contact Cowon, and request an RMA replacement if they can't help to resolve it.
