I have an Averatec 3150 laptop and the keyboard is going crazy. Page up and page down no longer work; sometimes several letters of the alphabet don't work; sometimes the delete key gets stuck and deletes everything it can. I tried uninstalling the driver and re-installing it. I tried attaching an external (USB) keyboard, which solves the problem somewhat. However, the original keyboard remains active also and so when the delete key decides to do its thing -- there's nothing I can do but reboot. Is there any way to completely disable the built-in keyboard? Any suggetions?
