Wii U Disc Reader

Up until now, my Wii U has been able to read discs perfectly fine. But today I turned it on, and it can't read any disc that I put into it, Wii or Wii U game. Is there any known way to fix this? Or am I going to have to send it in for repairs. I also severely hope that warrantee covers this, in case I do have to send it in.

Thanks for any help on the subject,
