Ipad disabled itself?

My Ipad mini has been dead an un used for a few months due to moving. It has been in my suitcase untouched for 4 months. I charged it and when it turned on, it was disabled for 26,134,324 minutes. I do not have a computer to back it up, nor has it been updated because my ipad would not allow me to do so. How do i fix this? I have priceless notes, photos and videos on this device. And i do not want to reset my ipad.
