Inspiron 1720 Touchpad under Windows 7

Currently I am having the serious problem related to which I need quick help from you guys. Recently I have a Inspiron 1720 and installed Windows on Saturday 7 Professional 64bit. Now makes the touchpad "trouble" Work. But it does not scroll the scroll areas. I have tried both older and newer but nothing seems to work in my case. Not even with the compatibility function. Contact the support and I cannot stop there my warranty has expired and therefore I must not even write an email. Someone has experience or any solution? For as long as I am desperate to find.

I had now found someone of you ever ne solution? I have the whole day trying everything possible. it does not work. If I take the drivers from the 1750 I have numerous options at least schonmal the dell touchpad. There I can only click the mouse pointer adjustment and external. With the scroll and touchpad setting, nothing happens when you click on it.

It is really like madness. I am already excited regarding this. I had read about it somewhere that there are also problems with the Alps drivers, but am not assume that one can simply take the Alps driver. I was even in on the Dell Inspiron driver side nerve only thought, that's the wrong touch pad. Well, now it works and I'm happy.

Oh, and one thing I still have. I have a basic device in the device manager that he did not recognize. Location: PCI bus 3, device 1, function 3. I have no idea what it can be. And ya I am requesting others if they have any solution regarding this issue then please help me as soon As it is possible for you guys. I just want to thank you in advance.

Any unfortunately not at all? As I said the only thing I remembered what is still built into the laptop and perhaps no driver has the express card slot is. Or do you mean driver for the slot where special comes in a sony memory card into the card reader? Where I would get for, or how hot? Please if anybody know about it then please help me as soon as it is possible.
