Hello,
First time posting on here. So I have a limited edition animal crossing 3dSXL that I got in July. About a month ago, I started noticing problems with the system. When it is in sleepmode, sometimes the system just shuts off or when I open the lid of the DS to leave sleep mode, it turns off. I have also noticed that the date and time keeps resetting. It charges fine, and it was not water damaged... I don't understand what is wrong 
Please help me!
Thanks
