I plugged in a Logitech usb stock which allowed me to run a wireless keyboard and mouse.,,The laptop set up the software itself. I took the stock out and the keyboard and mouse wouldn't work. Plug it back in and everything works. Turned the laptop off, pulled the stick out turned it back on and the keyboard works but the mouse wouldn't. Silly me disabled the mouse and now nothing works. Even tried control alt and delete, and nothing. Any ideas before it goes back to the shop in pieces. Rossco.PS...IT.ag still under warranty.
