Sony VAIO touchpad malfunction
The mouse works normally and after some random time of using the system, if starts to fail, meaning click buttons not working.

If I do:

rmmod psmouse
modprobe psmouse

it goes back to normal operation.

Using the search function I found this (very similar) post but unfortunately without a solution.

My system:

I have a Vaio too. If yours is still under warranty you could give Sony a call:
1-877-865-7669. Here's their website for support:

If not still under warranty you could have a computer shop (of course for a fee) to check it-
Or have Sony repair or replace it. They replaced mine but it was still under warranty.
It wasn't the mouse pad in my case; it was the corrupted recovery partition-

I'm not the expert on hardware but you could run Memtest86 to rule out hardware failure-

You said when you use these commands:

rmmod psmouse
modprobe psmouse

It goes back to normal.....but for how long till the mouse pad (click) stops working again?

Also which make and model of the Vaio do you have? The E series or enhanced?
And how old is your Vaio?

In some cases if people have performance problems with their computers hardware a newer versions of the kernel installed solves these problems. I'm not sure but maybe rolling back to an older version may help too-
Like I said I'm not the expert but giving you information that I have learned can help.

I see in your output you are running 3.2.29; version of the kernel-
Did you recently install the newer version of the kernel; 3.6.6?
Knowing what distro you have might help too-
What distribution are you running?

I have had the kernel disable an interrupt on suspend or while running. As I never used dsp1 in one box(hdmi soundcard), it regularly was disabled at some point. Is there suspends/hibernates involved, or is this powered off every time?

I never had to look beyond getting the synaptics driver in there before the evdev. I see 3.2.29; Slackware?

goossen 11-20-2012 04:45 AM

Yes I'm using Slackware 64 bits.

Ztcoracat: The model is VGN-CS290 and it is not more in warranty, its a pretty old machine.

business_kid: The NB is powered all the time, not even screen saver involved.

I found repair parts/replacement parts for your Vaio if your interested-
Here is the manual for "Troubleshooting"

I'm not sure if the mouse pad can be ordered/replaced but I'd give it a go if it were me.
If your not really up for replacing the pad yourself you could have a computer tech replace it for you; that is if you want to at this point. (Be careful with your hands not to stir up an electro-static charge) Not sure if (eventho it's not under warranty anymore)Sony would repair/replace the mouse pad or not....I'd call them and ask.

The only other idea I can think of; Goossen is purchase a wireless mouse that comes with a dongle that plugs into the side of your Vaio and try that. As soon as I purchased my Vaio that's the first thing I did-
