Turn off Frozen TP2 without taking out Battery?

[Cmk618]

Hi I have a verizon Tp2 and Im currently running Mighty Rom on it. Every once in a while my Tp2 freezes (not very often I admit) and when it does the only way for me to get back and running was by restarting it by taking out the battery which used to be no big deal but now I have a case on it that snaps on and is a real pain to get off. So i was wondering if there was a way to turn it off when its frozen without taking the battery out.

Any help is appreciated and Thxs in advanced.
