Can you just replace his power button and use that to turn it off? I've done that with my iPod Touch 4th gen, and it works just fine (I could have been lucky). Of course, if you don't have the parts then that's not an option. If you don't have the parts could you pull one off of a working/broken extra? Without a power button physically attached I don't know of any ways to turn it off though, sorry.
