why won't my ipad switch on?

Without more details we have no idea. Is it charged?

The following are some common steps to fix the problem. Hope it is also helpful.

1. Try to reset. Hold both the home button and the wake/Power button down at the same time. You should see the Apple logo appear on your screen after holding these buttons down a couple of seconds.

2. The iPad comes with both a 30-pin connector and an adapter that allows you to plug it into a wall outlet. Use this to charge the iPad rather than plugging it into your computer. After letting it charge for at least thirty minutes, try repeating step one.

3. If your iPad still won't turn on, there may be a hardware failure. The easiest solution is to locate the nearest Apple store.
