My problem is that my left click button for my mouse control activates by itself. If the cursor is over a clickable button or another screen, it will activate that button or open that screen. If I'm typing, my text will suddenly transfer to where ever my cursor happens to be.

I'm not using an external mouse, just the one below the keyboard. My computer is a Sony VAIO VGN-T150P.

Contacted the Sony people once, and they suggested downloading and re-installing my mouse driver in Safe Mode, which I did (file name SODOTH-00201205-US, Sony PCG-UMS1 USB Mouse Driver for Microsoft). That did not help, assuming I did it correctly. After that they suggested restoring my computer to a time before the problem started. I really don't want to that if I can avoid it, since I have this problem for a while now.

Any suggestions?

Are you sure you aren't accidentally brushing it with your shirt or something as you type? Touchpads are notorious for this.

If you shut off the internal touchpad and then use an external mouse, does it still happen?

Billy3, I'm sure I'm not touching either the left-click button or the touch-pad when this happens. And unfortunately, I have no external mouse to plug in.

Alright.... Sorry, had to ask. I had an issue like this, but it was because my wrist kept touching the pad, making it click.

I seriously doubt this is a software issue... My best guess would be that there is a hardware problem.

I agree, this is a hardware problem. In fact, I reinstalled a clean OS and it started acting this way shortly after the install. This is a problem that plagues many Sony laptop users, apparently.

Apparently, there is a problem with the design of the touchpad, in that it shorts on the aluminum palmrest because Sony decided not to put any insulation there between the aluminum and the touchpad circuitry. So, if your hand is heavy enough when it rests on the palmrest, it will cause the aluminum to touch the circuitry and make the touchpad seemingly go berserk.

Well, you can try this:

Or, if you have long fingernails (like me), you can hook them under the palmrest (between the touchpad buttons and the palmrest) and pull it up a bit.

Sony is just being irresponsible.

I find that some touchpads are just too durned sensitive to use and will disable them from starting (in the BIOS or as Windows boots).

Years ago I had an external touchpad - but haven't seen any of them recently.

As a workaround, I'll use a USB mouse - and I prefer a wired one so that I don't have to fuss with the settings/recognition of the device.

EDIT: Here's a link to a google for the external touchpads: http://www.google.com/products?q=external+...=1&ct=title
