Hey There I have Recently Unboxed My Hp Probook 4520s notebook pc .
When I Connected Battery . Connected Power. And Turned On The Power Button
It loader windows and showed home screen .
But when i tried to use the touchpad it does not worked
I also tried to double tap the corner light but it again not worked
i also checked out the control panel foe enabling the touch pad but there it is showing in synaptics corner that there is no such hardware installed
I also tried to update driver software but nothing happened
