I have a Vaio Series F laptop (less than 2 years old) and I've just started to have a problem with the touchpad. Every once in a while (it seems to be around every 5-10) it becomes unresponsive to any movement (I move my finger on it and the cursor stays in the same place). If I tap it or click de 2 buttons below it (left click / right click) that still works, but not the movement of the pointer.
It's something that just started to happen today, never happened before. This unresponsiveness seems to last for like a minute, then the mouse works normally again, and then the same problem happens again, over and over, making it totally unusable.
I've restarted the laptop several times, updated Windows 7, unistalled and reinstalled the driver... but the problem still happens. I've also deleted to programs that I recently installed, but still the same issue.
Any ideas of what might be going on? Or were should I start looking?
