Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. You can then do a backup

Try a rest: Simultaneously hold down the Home and On buttons until the iPad shuts down. Ignore the off slider if it appears. Once shut down is complete, turn the iPad back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.
Also, as soon as you have WiFi connectivity and the time, manual do an iCloud back up (Settings App > iCloud > Storage and Backup > Back Up Now. You should have it pluged in when you back up (you can also set up the automatic back up setting from here.
