Hi, after 10-15 minutes working on my computer, the touchpad freezed. It won't move. The pointer is stuck. Not working eather right or left button. This is happening every time. But when i put my usb mouse, than seems to be ok, it's working. Without usb mouse works for 10-15 (than freeze) - with usb mouse is working perfectly fine. What seems to be the problem with my touchpad? Thanks.
