My Sony VAIO laptop's (SVE14A2M1EB) touchpad freezes once in a while (say every 2-3 minutes, but it's very variable). It suddenly stops responding completely for 0.5-10 seconds and then spontaneously works absolutely fine. When it freezes, no feedback anywhere on the touchpad makes it work again, ie. there isn't a dead spot somewhere in the touchpad.

I have Synaptics Clickpad V8.1 for modifying mouse properties (ie. SmartSense, sensitivity etc.), and one of the options shows me the cursor location/input location (see the last picture in this thread posted by japzone - the map on the left shows, when activated, the location of the curser Use touchpad while "typing"?), and here's the thing: While the mouse is completely frozen, the "cursor location"-map actually shows, that the mouse is working, ie. it follows the touchpad input. That makes me think, that it's not a hardware problem, but more of a software problem.

Other than that, the multifinger gestures and the tapping doesn't work sometimes. Both when the touchpad is frozen and isn't. That isn't a problem for me, but it might be helpful trying to diagnose the actual reason for the problem.

I've tried to:

  • Install drivers (and other things) from the laptop's support http://www.sony.co.uk/support/en/product/SVE14A2M1EB/updates
  • Try toinstall drivers directly from Windows by letting Windows search for the drivers itself
  • I've also tried to change the settings in Synaptic Clickpad by increasing/decreasing the different values like sensitivity
  • I've also tried to change the settings in Synaptic Clickpad by increasing/decreasing the different values like sensitivity
  • Reinstall Windows 8
  • Turn the laptop off, remove battery+charger, keep pressing the on/off button for a while, and then plug everything back and turn it on.

EDIT: I've plugged an external mouse and it works fine. It doesn't solve the touchpad problem though.

What about the Windows 7? did you have same problem in win7? –  Sam Aug 17 '13 at 13:11
    
I don't know since the laptop comes with Windows 8. Do you think that the OS might be the problem? –  Ali Aug 17 '13 at 18:56
    
hard to follow you, but if you attach an external mouse will it work while your touch pad freezes? Can you maneuver with keyboard shortcuts while your touch is frozen? I would remove all traces of the touch pad utilities and drivers, and start from scratch and add software slowly until it acts up. –  Logman Aug 18 '13 at 1:45
    
@Ali, such a nice name, I love that :) , you know, Windows 8 has many problem with some hardware, so if it possible,change your windows or check it via compatible mode... –  Sam Aug 18 '13 at 5:08
    
@Logman: I've edited the post: External mouse via USB works, but doesn't solve the touchpad problem. –  Ali Aug 18 '13 at 12:24
