Thanks a lot for that reply,I attached a usb wired mouse and it seems to have worked,took a while to find out how to disable the touchpad,quiet simple once you know just use fn button+f7 I have just typed a long letter and have had no problems,but very strange not to have a touchpad,I will look to see if it is possible to make the touchpad less sensitive and try that at least I have a solution,thanks again.
