Without warning my laptop touchpad and mouse started having a mind of it's own today. The pointer randomly scanned the screen making its own choices. First it was the touchpad. I looked up suggestions online and removed the battery. That did not work. I plugged in an external mouse which worked for about 10 minutes then started dong the same thing. I am running on AC Power only right now. Battery is still out and power cord in. About 10 minutes ago 6 downloads popped up on my screen so I loaded them. It is acting better but still allows mouse cursor to float wherever it wants. Any suggestions? Thanks.
