This might just be a thing that I have to put up or (hopefully) something that can be corrected. I bought my wife an E310 about 5 years ago, and she always used to tell me that it went through power very fast. I would check it over and not see anything wrong. However a month ago, I was checking it over again, and switched it off, 4 minutes after, it switched itself on again, then 30 seconds later it switched off, then 4 minutes later on again, and this repeated all night. Does anyone know why this is happening and how to stop it. (It does this even after a factory defaults hard reset too)
