Hi there and welcome
You do not ever power off the iPad fully, its not like a computer, you just press the power button once which powers off the screen but leaves the iPad running (it uses little power)
It is designed to work this way, and will work fine in this manner.
The power button is the one at the top right that turns the screen off and on.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
