I've just installed Windows 7 on an Alienware D900T and can't get the touchpad to be recognized. I've installed the original drivers and some Vista drivers for the D900K and tried the latest Synaptics drivers without seeing the touchpad device show up. I'm at the point of buying another touchpad on eBay and see if it works. Does anyone here have any experience installing Windows 7 and getting the touchpad to work?
