My fiancee got a Dell Latitude E6510 and all of a sudden the touchpad stopped working. I tried a lot of things, but the touchpad just won't work. I tried updating the drivers, downloading and installing the driver "DELL_MULTI-TOUCH_TOUCHPAD_A04_R269801" from Dell consumer support, and even updating the bios. I am really frustrated and don't know what else to do. Can someone please give me a hint on what I could do to get the touchpad to work? Thanks a lot.
