did my one day old Sansa Zip just die?

the screen just went black when the battery still had more than half the bar, now it would not turn on at all. 

This is my second Sansa I bought and second Sansa that had problem…

don’t know what happened but reset it now it’s back, battery is like 90% full. Don’t know why it just temporarily died.

Reset. Hold Power Button over 20 Second. Leave the Power Button and Press Again the Power Button.
