Why does nothing happen when I press the power button on my Casio Cassiopeia E-200 Handhelds?

This issue may occur if the main battery is weak, in which case you should charge the battery pack. Alternatively, there may be an internal malfunction. Try resetting the unit. If resetting doesn't fix the problem, perform a full reset (memory initialize).
