RE: Touchpad issues in Dell Inspiron 11 3147 (Windows 10)

This fixed my problem:

1. Search for "update device drivers" without the quotes in the taskbar

2. open up the "system devices" tab

3. double click on "intel serial IO I2c es controller

4. click "update driver" in the drivers tab

5. select "browse my computer.."

6. select "let me pick from a list of device drivers on my computer

7. select "intel i2c Controller"

8. Restart computer

That fixed it for me, but I'm not sure if it will work for you.
