I have it broken now too. It can be replaced by desoldering and soldering a new one. They are cheap on eBay. If you can't fix it yourself take it to a phone/computer shop.
My phone autostarts when connecting the USB port because i am using devil kernel, and i have slim bean ROM, with hardware keys enabled and the function to turn off the screen assigned to long press menu button. I can also turn off the phone using this ROM via another touch controls in the drawer (long press over turn off touch button). So i don't have to take the back cover off.
P.S: i supposed that you were talking about the screwed internal back cover. If not, and the problem is with your plastic material then another solution should be possible.
