Can I replace the battery to my ipad myself or do I have to send it in?

see if this helps you out..
To resolve this you need to alter the port that your iPhone or iPad uses to send mailwhich can be done as follows. Go to Mail, Contacts, Calendars and select the account you wish to change. On the next screen, scroll down to the "Outgoing Mail Server" section and select the SMTP server that is listed.

Incorrect port part, Wrong polarity for wires connected to the port or poor connection of wires to the port.

Go to settings / Mail, Contacts, Calendars then find Always Bcc myself and switch it off.

My ipad has done this twice. Both times it has been due to the battery going totally dead and a bad charger cord. Take it to a radio shack or to someone and have them to use one of there chargers wait a few mins. See if it begins to show any signs of taking a charge at all. It may take 20 mins. or so. If it doesnt then you will more than likely have to replace the battery inside the ipad. There have been some ipad batteries that havent lasted very long. Good luck and I hope this helps you.

You probably locked the screen rotation,
to fix this:

1. Rotate iPad so the display is in the desired orientation.
2. Double-click the Home button to display recently used apps.
3. Flick from left to right along the bottom of the screen.
4. Tap the Screen Rotation Lock button on the bottom left of the screen.
5. The lock will disappear

I just answered this for someone else. You can see how to improve your battery life here.
Since I'm nice I will post here too.

• Turn down screen brightness
  
• Don't play graphics heavy games
  
• Turn off location services
  
• Quit applications you are not using
  
• Turn off push notifications
  
• Set email to manual update
  
• Don't use 4G internet connection if possible
  

Does its battery is full or not? Try to charge it then turn on it, if not work, suggest you send it back to Apple , they will be helpful. Or get a new table pc if it was damaged.LOL
