Two months ago I bought a Dell Latitude e5530 running Windows 7 64-bit. About a month ago the Alps multi touchpad stopped working out of nowhere. The buttons were the first thing to stop responding, followed shortly (minutes) later by the touchpad itself. After trying many fixes including uninstalling and reinstalling the driver, updating the driver, uninstalling the driver and letting it reinstall automatically on restart, doing a system restore, I finally had to reinstall the OS, after which it worked. Since then, it has stopped again about 5 or 6 times, completely at random, out of nowhere (i.e., not on a restart - just when I'm web browsing, etc). Each time I have eventually gotten it working again after trying a bunch of different things, and so far there isn't a reliable pattern to what makes it stop and start again. Sometimes it starts after I do a system restore, sometimes it doesn't. Sometimes it stops right after a Windows update, sometimes not. So I don't think it's a hardware problem, but beyond that I have NO idea what the problem and/or solution is. Halp???
