My samsung intensity wont turn on?

[saam]

Okay so first of all, there was this problem about my qwerty, everytime i slide it my screen would just turn off, like the screen but not the phone, so i would have to turn it off. And the end button dont work that good. Cause i dropped it many times hah. But i went to turn it off because i accidently opened the keyboard, but now it wont even turn back on? It's been an hour, usually it turns in in like 5 minutes, but its like an hour and it wont turn back on? Like it charges, but it wont turn on? HELP ME, is there like any other way to turn it on? UGh, HELP. PLEASE. :'(
