Are iTunes and the iPad not getting along? An iPad needs to connect to iTunes for important system updates and backing up your applications and data. But before you run out and buy a new cable, there are a few things we can check.
First, let's make sure the computer is recognizing the iPad. When you connect your iPad to your computer, a small bolt of lightning will should appear in the battery meter located on the upper right-hand side of the screen, which signifies that it is charging. However, not all USB ports are capable of charging the iPad, in which case the words "Not Charging" will appear next to the battery meter.
If you see the lightning bolt or the words "Not Charging," your computer recognizes the iPad is connected and you can proceed to step three.
