Simon, I just had a notebook touchpad "problem" - the cursor 'arrow' was dead center - but would not 'move'. So, I tried several 'complicated' efforts to 'repair' the 'problem', all of which were made difficult by the fact that, duh, although I could get online with the 'windows' key, and could get to certain topics by using the tab and the < or > key, I could not use the cursor to select exactly what I wanted. Likewise, I could get to the control panel, and the mouse, but could not select the tab on the mouse file that I thought might give me an answer to why the touchpad was not functioning. Then, I checked with PCGuide dot com. I entered 'touchpad not functioning', where I found that what had happened was, the bar-type switch that's on the notebook keyboard face, just above the touchpad, had gotten 'clicked' to the 'off' position. Because I use my notebook in a faily bright area, the 'blue light' that indicates touchpad function was not noticed as being 'dark'. I never even realised that the 'bar' style button that's between the touchpad and the spacebar HAD any function!! So, silly as it might seem - give a look at your pc, and see if there's a similar button! Good luck!!
