Help. Every time I try to open an Internet page it closes before opening all the way up. Last night I didn't realize my ipad 2 wasn't charging then in my attempts to shut it down I "overdrained" the battery. To less than zero. So I have rebooted. I have gone into settings and reset back to defaults but I still can't open a page all the way up. The bar that shows its opening gets about half way then it shuts down and I am back on my home screen. I use safari.
