So, I've got a first generation 3DS system. Sometimes when I close it and put it in sleep mode, it will shut itself off at that time instead of going into sleep mode, and I have to hit the power button to turn it back on. Not always a big deal, but sometimes I'm at work and carry it around with me for streetpasses (hence, not always being able to check and see if it's in sleep mode or shut itself off).
Does anybody else have this problem, or what did you do to fix it?
