Your touchpad lagging, stop working? click and drag, left click, right click just do whatever they want essentially or are unresponsive? There is only one real fix. It is not software related, it is hardware related but there is a simple fix..
I have done it and a lot of others have as well.

Do this and your touchpad will work flawlessly. Or you can keep reinstalling drivers and hitting FN +F11 until your fingers bleed and make no difference what so ever..
