Trackpad issue

2015-07-21, 7:13 AM

I'm sure that this question has been asked on this forum before, but I can't find a solution. So please direct me!


My trackpad and trackpoint on my S1 Thinkpad Yoga randomly stop working. Sometimes the cursor disappears, sometimes not. Sometimes closing the lid and reopening it (logging back in after sleep) bring the trackpad functionality back. Sometimes not. Sometimes restarting fixes it. Sometimes not. 


I have seen Yoga (non thinkpad) owners complaining about a service called "YMC," which apparently turns off the mouse and keyboard when the device is rotated, causing this behavior. But I don't have such a service on my Thinkpad Yoga, so am stumped as to how to address this.


Please help!
