There is an issue with my 2011 MBP display. How should I handle this?

I've had my new computer for 10 days. I marked this thread urgent because I want to figure this out while I'm still in the return window.

I have my display screen set to sleep after 1 minute. When I put on iTunes to go to sleep to, and dim the screen all the way to darkness manually, the screen lights back up after 30 seconds. Then 30 seconds later (at the 1-minute point since the computer has been idle), the screen does go to sleep.

I tried setting the display screen to sleep after 2 minutes. When I put on iTunes, then dim the screen all the way, it again pops back on after 30 seconds. Then it takes 90 more seconds (until the 2 minute point) to go to sleep, just the way I've set it.

My computer isn't working right if it won't stay dark manually.

Would you bring it in to Apple to look at if you were me? Could they do anything here? I don't want these flaws in my computer, and since I'm still in the return window I want to know if anyone thinks it's an issue unique to my computer that I could remedy by returning it and getting another one. Maybe someone could see if this also happens with their computer.

Thanks a lot.

 

Yes, changing that makes the display not do that. Is that common in other people's computers as well?

So this is a standard thing, then? If it is that makes me much less concerned. Thanks for your info

 

Looks like it shuts it off/sleeps it completely, since it doesn't have that slight, infinitesimal glimpse of the screen you still have when the brightness is put to its lowest setting.
