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.
