My touchpad is not working after upgrading to Windows 8 Professional. I have a Lenovo Ultrabook u300s, the touchpad i believe is Cypress Trackpad. The mouse cursor simply doesnt move but I notice if I click the button it will response. I have installed the latest driver from manufacturer support website. The only way i can get it work is to remove the driver, but the standard drivers by Windows doesn't have the palm detection. Notice also the key button (F6) to disable the touchpad doesnt work anymore?
I didn't find the right solution from the Internet.
