7250 Won't turn on/off??

Just got my first BB last week, and loving it so far. One problem I seem to be having - the on/off button doesn't seem to work on my used 7250. I can turn it off using the icon, but can't turn it back on with the button.

I have to take the battery out and put it back in to reboot the device. :confused: Any ideas??

Does the screen go black? If it does, the BB doesn't turn off completly. Its like a standby mode times two.

No, it doesn't do anything. Doesn't go off, doesn't turn on. Only way to restart is to remove the battery and put it back in.
