Recently the track-pad stopped working so I started carrying a mouse around. Annoying but not life-threatening. But
I tried quite a few things and after some frustration and trial and error I came up with
1. Turn off the laptop
2. Remove AC power if plugged.
3. press and Hold Power button for more than 60 seconds.
4. Then, Start the Laptop as Usual.
I know, I know.. It makes no sense but it does resolve the problem. Both trackpad and keyboard are back to work now. I was about to start a search for the next “Top Model”
Let me know if this was helpful in the comments
