I have a 3000 y410...lately, whenever I am typing emails, (which are web-based..yahoo mail, gmail, etc.), the cursor jumps randomly to a new location. I have been very careful not to touch the touchpad, and have checked "disable pointer when typing," in the mouse settings thru control panel (as recommended by Lenovo tech support). I've updated to the latest Alps driver on the website, with no change.
Did you tried turning off the touchpad? I have experienced this problem. Even though I took utmost care about not touching the touchpad while typing, I felt that I uknowingly touched it a lot of time. So, to verify this I turned off my touchpad and then typed and didn't experienced any problem.
So, turn off the touchpad once and then see if the problem still exists.
