Does the Wii U have a sleep mode?

My screen on the gamepad is constantly on if I'm keeping my wii on. Is there a sleep mode or anything? I hate to let the screen just run like that

Don't know if you've read the thread with a similar concern, but you just need to push the Home button, look under Controller Settings, and then select Display Off.
