You have several options if you are having trouble with your iPad 2. You can go directly to an Apple store, contact technical support online or by phone, or look for a solution online.
If there is an Apple store or Apple authorized service center in your local area, you can take your iPad 2 in for a live person to diagnose the problem. Apple also provides technical support over the phone or online chat. Apple's website provides support documents for their products, allowing you to search for the answer independently. Finally, there are support communities on the Apple website that allow you to get answers from fellow iPad users. All of these options can be found on Apple's support website at www.apple.com/support.
