This guide will show how to open and locate the battery connectors . You don't need to remove the battery just disconnect it . that said you also do not need to remove the video cables in steps 5 6 and 7 so skip straight to step 8 once you have your tablet open . Hope this helps
try disconnecting the battery and leave it unplugged for five minutes or so . this will wipe the cache and give you a fresh boot
