I have an Acer netbook for the last 14 months. Suddenly today, the touchpad barely works at all. I checked the control panel, nothing strange there, nothing disabled. There is no mouse attached.
This is the strangest hardware failure I have ever seen. Also, for most of the time, the mouse cursors/pointers are invisible and stuck to the bottom left on the screen. I can hit CTRL to reveal location of mouse pointer. The point settings for the default Windows pointer set.
