My track pad was working intermittently and having a mind of it's own. Instead of going to a repair shop for a pricey fix, I followed this guide and removed the track pad, cleaned it up and hey presto it's fine now! Thanks for the guide, very easy to follow!!

How did you clean the track pad? Did you just clean the connector. I'm also having similar issues, my tack pad starts having a mind of its on randomly after few minutes/hours.

dirt can get trapped around or under the trackpad, causing touch malfunctions. removing this dirt usually fixes touch issues and maybe sometimes a click issue if dirt is under the trackpad

Does anyone have anymore information on the adjustment screw mentioned by John Tipton on Nov 6? I have made some adjustments to it and found tightening it actually locks out the ability of a USB external mouse from operating, and does not correct the problem of the internal track pad click function failing to operate. I suspect adjusting it properly may fix some of our track pad issues, but I have not discovered the proper way of making this adjustment.
