heres what its doing, when I plug in the charger it beeps but shows nothing on the screen. I connected it to iTunes and it locates the iPad bit gives a warning that iPad needs updated or restored but still shows nothing on the iPad. I did a complete restore through iTunes but then gives the same warning that there is a problem with iPad and may need to be updated. still shows nothing on screen. I've held power and home button at same time, different chargers. any more ideas?
