Hi

I hope someone can help. I have bought two PCG-71312M series laptops.

Both seem to have the same problem - the touchpads seem to have minds of their own. This is most annoying when connected to the internet - pages skip back & change seemingly on thier own. The magnification settings also change on their own. Sony support suggested reinstalling the drivers which I did and it has made no difference. If you use an external mouse via USB there is no problem.
