I bought DELL VOSTRO 2420 laptop 2 years ago. now a days, i'm facing a irritating problem. When i turn my laptop on, i see my touchpad not working. after using external mouse, i uninstall the touchpad driver i again install it . after restart it, everything becomes ok.
But , after shutdown when i turn on, the same thing occurs, mouse pointer gets freeze -_- .
what should i do ?
ps - some buttons of my laptop's keyboard (qweruiop) stopped working before the touchpad incident.
