My nintendo 2ds wont turn on

My 2ds doesn't turn on when I press the 'On' button, it was working fine the night before, but the next morning when I tried to turn it on it didn't work.

I tried charging it, and the charging light turns on, but it still doens't start. I also tried exchanging the bateries with my brother's and it still wont turn on.

I haven't dropped it, it hasn't been exposed to water, I don't know what could have happened.
