Inspiron 7573 2-in-1 Touchpad issue

For several months, my touchpad has been behaving erratically. Every few days, the screen cursor disappears. When I restart the computer, the touchpad is able to move around and click things but I am no longer able to use multiple fingers to scroll or zoom. In addition, when this problem occurs, my cursor also randomly moves to the left whenever I am typing. Typically, after a few days, the touchpad will return to normal operation, but then return to the erratic state a few days later.  I checked the drivers each time this problem happens, and it appears that the PS/2 mouse driver is working properly, but that the HID compliant touchpad is a hidden driver because 'the touchpad isn't connected to the computer', which it very clearly is. 

Some notes about my computer: It was purchased in August 2018. The screen was replaced early this year after being damaged. A few weeks ago, I was having a similar disappearing driver problem with the wifi network adapter, but this problem was fixed when I updated the BIOS software. 

I would appreciate any assistance on how to solve this problem.
