My friend recently opened his laptop (Lenovo 3000 V100) to see if he had a dedicated graphics card. After opening it up, he found his Touchpad no longer works (including buttons). The keyboard works fine, the system can recognize the touchpad and says it is working fine. It also says there are no driver updates. We attempted to uninstall the driver, but it didnt actually uninstall anything.

The operating system is Windows 7 Profession.

Any suggestions?
