After a hard reset because of non responsive behavior, the phone won't respond at all. Why is this and what do I need to do?

Q: why when connected to the computer does the phone shut down?
No, that simply does not, or rather should not happen.
If the device is unresponsive, try a reset by pressing and holding the home and power buttons for 15-20 seconds until the white Apple logo appears.
