My Casio fx-991ES plus just suddenly went off and few minutes later, it started displaying the 'casio' logo on its screen. Whenever I press any of the keys, it's the logo that still remains on display but whenever I press the 'on' button, the calculator goes off and few minutes later again.. it starts displaying the Casio logo again. It's a new calculator. Pls help.

Probably the battery contacts are loose and are not making good contact.
