My iPad is completely locked up
I've been using ios devices since they came out, long before they were called ios, and this is a first for me. I have an ipad 2 that is completely locked up. the two button restart doesn't work, and itunes doesn't see the device when connected. it almost seems to me like there an an internal fault like the battery has became disconencted or something of that nature.
aside from going to visit a genius, is there anything else I can do on my end to try to recover the ipad?
