pure i20 charging on Ipad3

Hi Water_Lover,

It sounds like you have a dock for your iPad that does nto seem to be functioning correctly. I would use the troubleshooting in the following article to help troubleshoot the iPad side of the equation, named:

If you need help with iPhone, iPad, or iPod touch accessories

Check the compatibility

Make sure the accessory is compatible with your device. If the accessory is on the Apple Online Store, you can see if your iPhone, iPad, or iPod touch model is listed as compatible.

If your accessory uses the 30-pin connector, you might be able to connect it to your device using the Lightning to 30-pin Adapter or Lightning to 30-pin Adapter (0.2 m).

See if your accessory's compatibility is limited. For example, some accessories might not charge iOS devices if they use FireWire instead of USB to charge.

Update your software

Install the latest version of iOS. You can see which version is on your iPhone by going to the About screen.

Disconnect and inspect the accessory, then restart your device

1. Disconnect the accessory and turn it off, if possible.
2. Inspect the connection between the accessory and device and make sure that no debris or other damage is present.
3. Restart your iOS device by turning it off, then back on. When the Home screen appears, reconnect the accessory.

Try a different device

Make sure the issue is with the accessory, if possible. Always use an identical or similar, compatible device with the accessory you're troubleshooting.

• If there's static coming from the left audio channel when you use headphones, try connecting the headphones to a similar device.
• If the device isn't syncing when connected to the dock, connect it directly to the computer using the Apple 30-pin to USB Cable or try another USB port.
• If you're using Lightning to 30-pin Adapter in a connection chain, try using the same adapter on a similar or identical device.

• Restore iPhone, iPad, or iPod touch

  Restore your iOS device. You should rarely need to use this step with an accessory issue. If the issue only affects a third-party accessory, contact the manufacturer before restoring the device.

Thank you for using Apple Support Communities.

Cheers,
