NDS - Hardware, Devices and Utilities -> Wii - Hardware, Devices and Utilities?
If you haven't messed with it physically as putting in a modchip, or messed with the drive in any way.
Then no. But who cares? They still have to replace it if you send it no matter what.
I recently sent a DS in that has been opened tons of times. Even had Flashme installed. They still fixed it.
Don't worry. They won't care.
