I have a new Lenovo Y410p that came with Win 8 but i downgraded to Win 7. The problem is that sometimes when i leave the computer on but dont use it, it starts randomly clicking on things. It's like if some1 is randomly using the touchpad and clicking. Is there any program or app that locks the touchpad so I can just do that while my laptop is idle? I usually put it to sleep but sometimes when i leave the room to go to the bathroom or to eat, ill leave it on. Any suggestions?
