Inspiron mini shuts down by external dvd play

Hello,

I purchased a brand new inspiron mini laptop and an external dvd player from dell manufactirers. Everytime i try to play a dvd it shuts the laptop off, i disconnect the external dvd player and the laptop starts up from scratch. Its very frustrating as i cannot return anything and dall said it sounds like a software problem and i have to pay for even talking to someone. Please help me.
