Satellite ls7008. I have a laggy mouse when moving it with the touch-pad only. Every 4-6 seconds it stops then goes again. This is also happening when using the arrow keys on the keyboard when scrolling in a long web page. Now I am noticing input lag while typing. It does not do this when using a USB mouse(the mouse lag only). I have tried to restore, uninstall drivers, install new drivers(synoptics and Toshiba ones) and it still does it. I tried with and without a battery. I Turned off virus protection. Nothing has changed the input lag yet. Wondering if I need to reinstall windows 7 64bit as this really annoys me.
