Check the I/O port for any debris. Sometimes dirt will confuse and freeze the calculator.

You can try an OS reinstall. Take out one battery then hold [Stat] while putting the battery back in. It should say something like 'send OS new' or 'waiting for OS'.

Now plug the calculator into your computer using the USB cable and send the OS. You can download it from TI's website or directly from TI-Planet: http://ti-pla.net/a2111

It will take a few minutes to install.
