Help Power/Lock button no longer works


I haven't seen this reported yet.

My power/lock button no longer works. Phone hasn't been dropped, only had it for 3 days and it's been babied. I hoped pulling the battery and rebooting might help, but it didn't. In fact, after that the only way to get it to reboot was to plug it into my computer via USB.

I probably just got a rare issue here, but wanted to report it.
