Hello. I shut my ipad 2 down ths afternoon to save some battery life like you do, but when i did it, it didnt shut down prperly. ts stuck on the little round curcle that you get when something is loading. I cant turn it off and i cant turn it back on. Its just frozen wth this little annoying curcle constantly going round. Ive tried to connect to itunes to do a master reset but it comes up with there is an error on your ipad connot connect. Ive also tried holding the power button for upto 30sec at a time to see if that would work, but it failed. I could really do with some help. Does anyone have any ideas on what i can do please?
