About the first week I got my Ipad 2 two My cat chewed my charging cable. She has a habbit of chewing small cables for some reason. Anyway I went and bought a generic charging cable that was apple aproved and It has worked just find since I got it. The only draw back is its that it comes unplugged from the ipad often. I think I have used it for just under a year. Well this morning I was using it and every thing was fine I unplugged it for a bit and when I needed to charging it again I got the not charging thing poping up. I know that it means that its not getting enough power to charge something but I don;t know why all of a sudden its doing it. I even borrowed my mom's charging cord that came with her Ipad and its still doing the same thing. Its never been dropped or had any moisture poured on it or anything so Im not sure why all of a sudden its doing this. I don;t even use it that often usualy I will just watch a few movies on netflix or something and thats it. I know that when the screen is off it will charge but I would like to get it back to full charging power.
