I have a Toshiba Satellite C55 A, and the cursor freezes ALL THE TIME. The F5/FN key thing works some of the time to get it going again. Usually I end up doing a restart. But I need a more permanent solution, as it is impossible to get any work done when you have to interrupt what you're doing every 5-10 minutes or so. The other solution I've read about is turning the computer off and on again, removing the battery and replacing it again, etc. Do I want to do that every 5 or 10 minutes or so ????? NO. Has anybody else found a more permanent solution to this problem, or is getting a new computer the only solution? THIS PROBLEM HAS BEEN MAKING ME CRAZY.
