Resetting casio FX-115W

Casio fx-115W was locked into some sort of mixed-up engineering output but without the exponent. There is no reset method to my knowledge but by removing the battery and putting the calculator in a drawer for 30 minutes then re-installing the battery the calculator reset to default values and works properly.

I am having trouble finding a button on my calculator . The button that raises to a power greater than cubed.

Standard it says x^y or x with y superscripted. Insert the base, press that button, insert the exponent, press =.
