Date: 2012may10 Product: Acer Aspire One, ELAN touchpad Q. Why is the touchpad / mouse on my Acer Aspire One not working? A. Perhaps it was disabled by function key... Press function - F7 to enable it. In the control panel there's an option to disable the touchpad when a USB mouse is connected... make sure that isn't checked (if you have a USB mouse). Finally the good old standbys: - Uninstall and re-install the driver - Reboot
