Ran into an odd issue after installing SP1 for Windows 7 x64 on a Dell D630, the touchpad / pointing stick stopped responding.
Looking at driver download page for the D630 / D830 (Windows Vista 64-bit) on Dell’s support site shows there are no drivers provided for the touchpad / pointing stick.
I find the lack of updated drivers to be a common problem with Dell’s support site, the solution is usually very simple – look for a similar model system with the correct drivers. In this case the driver page for the D430 provides us with a 64-bit install package for the Dell touchpad / pointing stick.
You can go to Dell’s support site here and download it. Or you can also download it here:
