I have a Lenovo Flex 3 running Windows 8.1, and I can't find a way to make my touchpad stay off. The hotkey to turn it off at F6 does work, my trackpad will stop working for a time only to randomly turn on by itself or when I restart the computer.
I've uninstalled and reinstalled the touchpad driver, which didn't help. And, when I go into mouse settings in the control panel and go to 'change settings' when I select 'Lenovo pointing device' the option to disable the touchpad is grayed out. My account is administrator, so I have no clue why I can't click the disable button. Even Lenovo support couldn't fix this, I will be forever grateful if you can help me! I'm at the end of my rope here.
