Manok, what exactly do you mean by "it decided it wasn't going to work anymore"? How did it fail? How long have you had this iPad? Since the iPad has been out less than a year, and it has a one year warranty, it seems as though the warranty has not run out.

How long have you left it plugged in for before turning it back on again?

You must have taken your iPad to the low charge shutdown previously from your response so you know what that is like. When mine hits that point the shutdown is very fast, little warning except for the nag dialog boxes that keep coming up below 21% charge. Did you get any of those nags before this occured? Have you plugged your iPad into a wall outlet to recharge?

You may need to do a hard reset: hold both the sleep/poer button and home button until the Apple Logo appears and they unit goes through a restart sequence. If that doesn't work, have you connected to a computer and used iTunes to see what it says about the iPad? If so, what iformation/lack of info did it give?

If my warrenty has run out by now

It hasn't.
iPads (& most/all Apple products) have a one year warranty.
