Some times back I was unable to use my laptop mouse for a period of not more than six months and after soughting various sources I finally found a solution (I used solution number 4 as listed below).These are some of solutions to mouse or trackball poblems I propose: Install Axiotron-done by vendor who sold you you latop-they just put insulation to the motherboard. Undervolt your machine-using a cookbook ($10-cost) to run at lower voltages/higher processing speeds than the default. Restart pen driver using Activity minitor. Disable pointing devices in your BIOS(Click F2 on boot)Ref:sumsung np-x1 Solution number 4 solved my mouse/trackball problem for my sumsung np-x1 model laptop so I hope this would of some help to someone else who might be having related problem. Please let others know if this works by commenting after trying them out.
