Simple, you can't but you can turn it off and then back on by sliding across the power switch, and then changing the settings!
Edit:
you can also put your battery out of your DS, wait 45 secs, then put it back in.

There are two different ways to reset your DSi; A soft reset and a hard reset.
A soft reset can be performed by pressing L+R+Select+Start. This will return you to the title screen of whatever game you're playing at the time. (This works for any DS system.)
A hard reset can be performed by quickly tapping the power button. This will return you to the DSi menu. (Holding the power button will shut it down instead.)
