Hello out there,
I´m writing from germany, so please be patient with my english 😉
I got a problem with the touchpad on my new Sony FE41S. It worked fine at the beginning, but for now it simply refuses to respond (buttons AND pad). Only way to make the cursor move is to use an external mouse (which I normally do anyway, however, for usage in the train or any other short sessions I´d like to use my pad!).
The device-manager in the system area says, that the only input/pointing device installed right now is my external MS-mouse. Probably need to reinstall some drivers for the pad, but where do I find them (on harddisk / in Sony support / in the system area?). How are these driver called there?
Thanks a lot for your help!

Welcome to ClubVAIO
All the preinstalled drivers for your VAIO are in C:\drivers
Find the one that says pointing and run "DPinst.exe" and this should reinstall your drivers for it.
Does this help?

Hi,
thanks a lot for the fast answer.
I reinstalled the drivers, drivers are active in task-manager - however, the touchpad STILL does not respond. Running out of ideas 😞
Is there any keyboard-combination, that puts the pad out of action?
Thats what we are here for!
Try C:\Program Files\Sony\Setting Utility Series\VCCpointingdevice.exe
and check that the enable box is ticked.

It IS enabled. However, if I click on the "settings" button besides, the following window shows the settings of my mouse again, not of the touchpad. Seems like the Notebook does not "know" at all right now, that it hast any pad. Frustrating 😞

I think you will find that this model uses the Alps pointing device, in which case it will be Apoint.exe that needs to be run.
If that has no affect then try updating the device driver (possibly showing as a PS/s mouse?)in Device manager (right click and select update driver) and then point the wizard in the direction of either C:\Drivers\Pointing (if it exists) or download the pre-installed drivers for your model from Vaio-Link and point the wizard at the downloaded and extracted Pointing folder.
Maybe worth a full recovery to see if it is a hardware problem. If it is a hardware problem then Sony will fix it for you.
Back up all your data to DVD or CD etc.
Restart your VAIO and on the boot screen with the VAIO logo showing press F10 several times until the recovery utility starts.
Follow the instructions and this will return it to the factory settings.
If the pad still doesn't work then you will have to contact sony to repair it.

Is this a USB/wireless or PS2 mouse Calem?
Try rebooting your machine without this mouse attached and see what happens. If Device manager still reports no mouse/pointing device then you may very well be correct in your diagnosis that it is a hardware failure
