if you dropped it and cracked the digitizer the warranty most likely does not cover this damage

Try holding down power on switch for 5-10 seconds and see if you get a power down screen popup. If that doesn't work, look for a small hole on the back of the tablet or side that seems to have a piece of metal at the bottom of the hole. Poke this reset switch gently with a toothpick and see if the tablet resets (You can also check the manual for reset information).

Patty, I'm first assuming you can at least boot the tablet to the menu screen. Scroll over to the settings menu. Scroll down the settings menu to backup and reset. You then have two options given: Back up my data or Factory data reset!

Be sure nothing is pressing against the volume button when you turn it on, and that the volume button isn't being jammed down by anything.

in settings there is a section that you can turn auto rotate off you need to do this if you want it to stop rotating , you might be able to access the setting from dragging the menu bar from top of screen down like on a samsung
